Tektronix TDS2001C Digital Storage Oscilloscope, 50MHz Bandwidth, 500MS/s Sample Rate, 2.5k Record Length, 2 Channels, TFT Color Display Review
The Tektronix TDS2001C is a 50MHz, two-channel, portable digital oscilloscope with a maximum real-time sample rate of 500MS/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, and USB connectivity for electronics applications such as product design, assembly lines, repair and servicing, and electrical engineering education. The sample rate, which provides real-time sampling with a minimum of 10 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 7.0ns and various triggering features. The oscilloscope has a 5.7" diagonal 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) and a USB device port for connecting to a PC or compatible printer (USB cable sold separately). It includes 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 SignalExpress software (compatible with Microsoft Windows 2000, XP Professional, and Vista) for analyzing measurements. It meets European Standard (EN) and International Electrotechnical Commission (IEC) 61010-1:2001, Underwriters Laboratories (UL) 61010-1:2004, and Canadian Standards Association (CSA) 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 European Conformity (CE) marking. The unit comes with two 100MHz passive voltage probes, communications PC software, measurement analysis PC software, 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.

I've owned a Tek 323 since the 1970's and kept waiting for it to break so I could buy an updated Tek scope. I've bought a few other brands along the way, but none of them lasted long enough for me to even remember their names. I've also had a BitScope for a while, but I've never warmed up to its PC based user interface and cumbersome network interface (I should have bought the USB version). But my diagnostic work has increased lately, so it was time to get a PC-friendly scope with which I could join the 21st century.
This time, I wanted a self contained scope that could also connect to a PC for data capture and analysis. The Tek TDS2001C had all the features and specs that I need, so I took the plunge. I used an inflation calculator to see how much this scope cost me as compared to the 323 I bought (second hand) in the 70's. Turns out that, comparatively speaking, this new Tek is a tremendous bargain.
This TDS2101C easily has 100x the capability of my old 323. The on-screen menus are easy and fast, and after just a few minutes I found myself twisting knobs and hitting buttons without much thought. Although this scope is a very modern design, old timers like myself can quickly make friends with this new way to do things. (ah hem, not so with the BitScope....)
My only disappointment is the low screen resolution; traces on the the built-in display are only 320x240, and much of that space is occupied by the information surrounding the traces. Screen shots sent to USB are the same low resolution. I don't understand why this modern scope has less resolution than a smart phone. But the built-in screen is adequate to see what's going on with the signals, and to help set up for a PC based test. The captures to USB are also rather slow---about 5-6 seconds per shot.
Although the built-in images are not sharp, the actual signal data is much higher resolution. PC-based acquisition using the included National Instruments Signal Express software generates much cleaner traces from scope data rather than from the scope image. The PC software is fairly easy to use, and I expect that is the real intent for this scope.
So overall I am pleased with the scope and its capabilities, but next time I'll study the screen resolution a bit closer. After all, this is the 21st century---I don't want a Pac Man display on my high-tech test equipment.
