Low-Cost DSOs Surpass Bandwidth And Sample Rate Standards

The TDS2000 and TDS1000 digital-storage oscilloscope (DSO) families boast high performance in the low-cost marketplace. The five models in the TDS2000 line deliver 60- to 200-MHz bandwidths and a 1- or 2-Gsample/s rate in both two- and four-channel instruments. The TDS-1002 and TDS1012 two-channel devices have a maximum 1-Gsample/s rate and 60- and 100-MHz bandwidths, respectively.

All of the scopes come with a 2.5-kpoint record length. A P2200 200-MHz 10x-1x switchable passive probe is supplied for each channel. The TDS2000 instruments feature a standard color LCD for easy reading and interpretation of waveforms, especially when multiple traces are displayed.

Both families have fast-Fourier-transform (FFT) capability for easy and precise analysis, characterization, and troubleshooting of circuits. Advanced triggering—including pulse-width triggering, line-selectable video triggering, and an external trigger—speeds complex characterization and debugging. An autoset function offers automatic detection as well as a choice of different views of sine waves, square waves, and video signals. These views include rising and falling edges, video lines and fields, and FFT. The autoset function also provides up to four automatic measurements for the displayed signal.

Optionally, the TDS2CMA communications module provides communication with other instruments, peripherals, or systems through RS-232, GPIB, or a parallel printer port. The WaveStar software package lets users capture, analyze, document, and control measurement results by transporting data from the oscilloscope to the PC desktop.

The TDS1000 and TDS2000 series DSOs are priced from $995 to $2795. The TDS2CMA communications module, the WaveStar software package, and an operator training kit are priced at $265, $319, and $295, respectively.
