Tektronix TBS1102 Digital Storage Oscilloscope, 100 MHz Bandwidth, 1 GS/s Sample Rate, 2.5k Record Length, 2 Channels, TFT Color Display Review


The Tektronix TBS1102 is a 100MHz, two-channel, portable digital oscilloscope with a maximum real-time sample rate of 1GS/s per channel, a record length of 2.5 kpts per channel, advanced triggering, three basic math functions and FFT, 16 measurement parameters, waveform limit testing, USB connectivity, and an oscilloscope education resource CD for electronics applications such as electrical engineering education and hobbyist projects, among others. The sample rate, which provides real-time sampling with a minimum of 6.7 times oversampling, and the record length enable long capture times for displaying detailed waveforms. Both channels can simultaneously run at the maximum sample rate. Rising and falling edge, pulse width, and line-selectable video triggers allow isolation of specific signals. Three basic math functions—add, subtract, and multiply—plus FFT (fast fourier transform) and 16 measurement parameters such as period, frequency, and peak-to-peak enable an in-depth analysis of waveforms. To aid troubleshooting, the waveform limit test provides a pass/fail comparison of a triggered input signal to a user-defined setting. The data logging feature automatically saves triggered waveforms to a USB memory device for up to 24 hours. Additional specifications include a rise time of 3.5ns and various triggering features. The oscilloscope has a 5.7" color TFT (thin film transistor) LCD with a resolution of 320 x 240 pixels and an anti-glare surface for viewing waveforms.

The oscilloscope has a USB host port for storing data on a 64GB-maximum USB flash drive (sold separately), a USB device port for connecting to a PC or compatible printer (USB cable sold separately), and OpenChoice PC communications software (compatible with Microsoft Windows 2000, XP PRO, Vista, and 7) for transferring and saving settings, waveforms, measurements, and screen images, and an oscilloscope education resource CD featuring primers, instructor's guides, and student labs. It meets EN (European Standard) and IEC (International Electrotechnical Commission) 61010-1:2001, UL (Underwriters Laboratories) 61010-1:2004, and CSA (Canadian Standards Association) C22.2 61010-1:2004 safety standards, and is rated for CAT (category) II installations to 300V, which covers energy-consuming equipment connected to a fixed installation, including household, office, and laboratory appliances. It has CE (European Conformity) marking. The unit comes with two 100MHz passive voltage probes, PC software, an oscilloscope education resource CD, a certificate of calibration, a 125VAC, 10 amp power cord, and a user manual.

Oscilloscopes are electrical testing devices used to verify the functionality of equipment that generates an electrical signal. Oscilloscopes measure the voltage of an electrical signal over time, and display the measurement as a waveform in a visual graph. The waveform shows the sweeps (or refresh) of voltage on a vertical (Y) axis, and the time on a horizontal (X) axis. Details of a waveform demonstrate the signal over time. Most oscilloscopes have two or four channels for inputting a signal. Some digital oscilloscopes offer more than four channels, allowing channels to be dedicated to specific signals and applications. Bandwidth is the maximum frequency of a signal that an oscilloscope can capture. A constant image will display if a signal is shown at a high frequency. Oscilloscopes may be analog, digital, or mixed signal. An analog oscilloscope directly displays an input signal as a continuous waveform, typically in a luminous phosphor on a cathode ray tube (CRT). A digital oscilloscope converts the input signal into a digital format and reassembles the waveform for display, typically on an LCD. A mixed signal oscilloscope (MSO) displays both analog and digital formats. Some oscilloscopes can display more than one channel and type of measurement simultaneously. Some oscilloscopes can capture waveform signals to memory, and recall them. They may provide real-time intensity grading, and may have the ability to adjust frequency of display. Oscilloscopes can be powered with batteries or electricity, or may have a built-in generator. They are commonly used for testing, measuring, and inspecting in science, engineering, telecommunications, automotive, and electronics applications.

Tektronix manufactures test and measurement equipment such as oscilloscopes, signal generators, and protocol, logic, and spectrum analyzers. The company, founded in 1946 and headquartered in Beaverton, OR, meets International Organization for Standardization (ISO) standards 9001 and 14001.

5The TBS1102 is a fabulous advance from my old Tektronix analog oscilloscope
By Jeremy H. Jordan
Having used analog oscilloscopes for years, this digital storage machine is so much easier to use, a real time saver, especially because it does a lot of the work to get an image on the screen and with all the X and Y axis scale information. I look forward to exercising this scope's capabilities.

5It's a great Oscilloscope, even for hobbyists
By Jorge A. Ventura
I was planning to buy other brand for the same bandwidth (100Mhz) but after watch some reviews I got worried to spend $400 and get something without the quality that I require from this kind of device. Then I decided to pay more for the brand that I trust and I didn't regret. I love the scope and in the future if I have to buy another one, I will not blink to pay for Tektronix.

5Very capable o-scope with all the features you could want.
By Theodore E. Gill
I've owned and used oscilloscopes since I was about 16 years old (starting with a Heathkit I built.) As a Navy Electronics Technician in the 70's and 80's I worked with the legendary behemoth Tektronix 'scopes with all of the interchangeable modules and was always impressed with their superb functionality, stability, and performance. So when I decided to get an up-to-date 'scope to support my continued experimentation with electronics and embedded computing I wanted to get the best combination of features and price in a very-high-quality oscilloscope. So a Tektronix was the obvious place to start.

I have not been disappointed. This oscilloscope has all of the functionality of the big old analog scopes and more in a small light package, and that functionality is rock-solid. The features all work and work well. Tektronix is not trying to stretch the limits of what the hardware can do (with the resulting flakiness), but instead delivering stable presentation, accuracy, and helpful features. The display is crisp and clear, with many helpful annotations and messages. The controls are well organized, smooth and precise in operation. There are a number of helpful control buttons like "Set trigger to 50%" and "Center horizontal display on trigger" that are very useful time-savers. It's clear that this 'scope was designed by people who have used them. The "Autorange" and "Autoset" buttons are extremely handy as well.

This is my first digital storage oscilloscope and there are a number of features new to me that I really appreciate. The on-screen help is a great idea. It is well-written and actually very helpful. The ability to store setup information, waveform images, and waveform data either in the scope or in USB memory stick is wonderful. Built-in FFT analysis, while not the forte of the instrument, is very handy and useful and it's limitations are clearly explained in the manual. The ability to deliver images and settings data to a computer or printer via (yet another) USB port on the rear of the instrument is very nice.

Speaking of the manual, this is another place for a company to skimp and Tektronix has, instead, delivered an excellent, detailed, well written product. It has a section which is essentially a general storage oscilloscope primer as well as detailed instructions for this line of oscilloscopes and very complete lists of specifications and control functions. Tips for getting the most out of the instrument are inserted where appropriate and are very helpful.

Complaints: I don't have many. The Tektronix software for data transfer and display on a computer is a little clunky. The drivers have some issues on Windows XP. I haven't tried them on Windows 7 yet, but this often solves such problems.This is a low impact issue to me because I don't depend on this feature and in any case you can write the files to a USB memory stick and manipulate them on your PC that way. The images can be stored in several lossless formats and the data can be brought in to spreadsheet software for detailed analysis and plotting. I don't appreciate the NI LabView software come-on where they give you full use of their software for 30 days, then it falls back to the minimal version unless you spend $800. This may just be my particular pet-peeve but it always rankles me so I thought I'd mention it. Not really Tektronix's fault.

Summary: There are more powerful 'scopes out there and for much less money. But if you want a solid, reliable, full-featured, well-designed Cadillac of an oscilloscope that will deliver all the functionality it promises this line of 'scopes is a great choice. If you are a Maker-Space, an educational institution, or a serious electronics experimenter/inventor looking to acquire an oscilloscope that will meet or exceed your expectations the Tektronix TDS-2000 line will deliver.

5Quality never goes out of style
By W. Buckles
I have owned a Tek TDS 2014 for more than 10 years and have always found it to be the best instrument in my collection.

It gives me answers to questions I never thought to ask, showing waveforms that give me information that I didn't know was there.

Reliable, easy to use, clear controls, tolerant of abuse (CAT II voltage class). This scope is a good friend who never lies to me.

On the other hand, if you don't know how to use a 'scope don't bother with it - it's not a hand-holder and won't teach you what you need to know - that's what technical schools and the university system is for. Basic theory isn't this 'scope's forte and it will make a fool of anyone with a thin layer of understanding - this is a professional tool, nothing else.

3Seems to work
By G-Man
This seems to work. That's about as good as I can put it. It comes with absolutely no documentation what-so-ever and that would help. There are labels on most of the controls. It seems to be easily locked up and you can get it to display all kinds of odd artifacts on the screen. At odd intervals some of the controls seem to be unresponsive while others maintain functionality. The test leads that come with it are quite short, very thin and a bit cheesy. BUT in the end, it's a great bit of functionality from a oscilloscope that costs less than 50 bucks... Just don't expect it to be a full featured o-scope. Lastly, even a cheapo one-paged instruction sheet would be a vast improvement... If nothing else, perhaps someone could tell me what the little white slide switch next to the coaxial connectors is supposed to do.

4Tiny screen, works if you are aware of limitaitions
By Engineering
Really tiny display, but it works, and seems to be the newest version.

Some caveats:

- The display is really tiny, much smaller than the pictures makes it look. The display resolution is fairly coarse, probably less than the ADC can support, so it will be interesting to try changing the firmware to stream raw data to a pc.

- Like many "pocket" digital scopes, it seems to be missing a decimation filter. Slower time/div settings are accomplished by reducing the sample rate, which leads to a risk of aliasing fast signals as if they were much slower. If looking at an unknown frequency, you will have to start at the fastest setting and then slow down, to be sure that you aren't viewing an alias caused by undersampling. Another clue you are looking at an alias is that it may be impossible to adjust the trigger to stability - but set the scope to an appropriate sample rate, and it will trigger fine. In contrast, a good digital scope would have a decimation filter in an FPGA, such that the ADC is alway run at a high sample rate, and the slower display settings produced by filtering the signal to a lower effective sample rate and bandwidth - precluding aliasing of signals which meet the ADC's ultimate nyquist limit. But the ATMEGA cpu probably doesn't have the horsepower to do that at 20 MSPS.

- The trigger, position, etc adjustment are one button push per click, it's too bad they don't continue to advance if the button is held down.

- It appears to be possible to change the firmware. On JYE tech's website there is source code only for a very minimal version, but hex files for the version which comes in the scope.

- It would be nice to have a marker for the trigger time position. Also to have some indicator flash whenever it triggers, as it's not always clear if you are looking at a rock-steady display, or if the display is frozen because the trigger condition isn't met. Of course it has run/hold functionality and single-shot trigger modes as you would expect from a DSO.

- It would be nice if there were another decade of voltage sensitivity available - especially if you wanted to use a 10x probe.

- Buy a BNC jack to use instead of the RCA jack (looks like one should fit as the footprint seems to be the union of both) or at least a BNC-to-RCA adapter so you can use a real probe.

Building is fairly straightforward, but instructions are sparse. It may be worth consulting a picture to make sure everything is going together right. Don't solder the pushbuttons on the wrong side of the board! (they go opposite most of the other components). The occasional component lead which connects to the ground plane can require a lot of heat to solder, suggesting that there may not be enough thermal relief on pads which connect to the ground plane. In a few cases I ended up using a hot air rework station to put some extra heat into the board as I soldered ground connections with an iron. Make sure to mount the regulator on its heatsink before soldering, and be very careful of that middle ground lead as it won't regulate without a connection there, and the joint will be hard to get at once the LCD is soldered on.

4Great first O-scope
By Eric Fossum
Took me about an hour to put this together as a 4 out of 5 solderer. Documentation is horrible, but what do you expect. After assembly I would put a pulse width signal from an Arduino or something and get familiar with the controls before using. Also consider a two channel, I love this, but I needed to measure two signals just after first use.
