Specifications This section begins with a general description of the traits of the TDS 500C, TDS 600B, and TDS 700C oscilloscopes. Three sections follow, one for each of three classes of traits: nominal traits, warranted characteristics, and typical characteristics. Product Description The TDS 500C, TDS 600B and TDS 700C Digitizing Oscilloscopes are portable, four-channel instruments suitable for use in a variety of test and measurement applications and systems. Table 2–1 lists key features.
Specifications Table 2–1: Key features of the TDS 500C, 600B and 700C oscilloscopes (cont.) Feature TDS 600B TDS 500C & TDS 700C Storage Floppy disk drive: 1.44 Mbyte, 3.5 inch, DOS 3.3-or-later floppy disk drive Internal hard disk drive (option HD available on the TDS 500C and 700C) 170 MByte capacity Subject to change due to the fast-moving PC component environment.

Specifications general purpose knob to adjust some function, such as the position of measurement cursors on screen, or the setting for a channel fine gain. GUI The user interface also makes use of a GUI, or Graphical User Interface, to make setting functions and interpreting the display more intuitive. Some menus and status are displayed using iconic representations of function settings, such as those shown here for full, 250 MHz and 20 MHz bandwidth.
Specifications Table 2–2: Record length and divisions per record vs.
Specifications Trigger System The triggering system supports a varied set of features for triggering the signal-acquisition system. Trigger signals recognized include: H Edge (main- and delayed-trigger systems): This familiar type of triggering is fully configurable for source, slope, coupling, mode (auto or normal), and holdoff. H Logic (main-trigger system): This type of triggering can be based on pattern (asynchronous) or state (synchronous).
Specifications H Use sample, envelope, average and peak detect modes to acquire signals. With the TDS 500C/700C, also use high-resolution mode. H Set the acquisition to stop after a single acquisition (or sequence of acquisitions if acquiring in average or envelope modes) or after a limit condition has been met. H Select channel sources for compliance with limit tests. You can direct the TDS to signal you or generate hard copy output either to a printer or to a floppy-disk file based on the results.
Specifications For time measurements, units can be either seconds or hertz (for 1/time). With the video trigger option installed (Option 05), you can measure the video line number using the vertical cursors. You can measure IRE amplitude (NTSC) using the horizontal cursors with or without the video trigger option installed. Measure Digital Signal Processing (DSP) Measure can automatically extract parameters from the signal input to the digitizing oscilloscope.
Specifications The oscilloscope can also output copies of its display using the hardcopy feature. This feature allows you to output waveforms and other on-screen information to a variety of graphic printers and plotters from the TDS front panel, providing hard copies without requiring you to put the TDS into a system-controller environment. You can make hardcopies in a variety of popular output formats, such as PCX, TIFF, BMP, RLE, EPS, Interleaf, and EPS mono or color.
