Tektronix TBS1042 Digital Storage Oscilloscope, 40 MHz Bandwidth, 500 MS/s Sample Rate, 2.5k Record Length, 2 Channels, TFT Color Display Review
The Tektronix TBS1042 is a 40MHz, 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, 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 8.8ns 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) 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 an oscilloscope education resource CD featuring primers, instructor's guides, and student labs. 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, 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.

This little scope is perfect for my little projects. Yes I didnt' want to spend all the money for decoding serial bus signals and such on their MSO/DPO series... I don't have that kind of money. But this little thing does a great job for my electrical hobbies. I'll always buy a Tektronix these guys practically invented scopes.
