HP 70703A Digitizing Oscilloscope, 500 MHz

The HP 70703A oscilloscope was designed for use in ATE systems. In repetitive measurements, it provides 500 MHz of bandwidth. A 20 mega-sample-per-second sampling rate allows single-shot measurements to 2 MHz. Dual-time-base windowing allows for closer inspection of pulse edges. Automatic measurements, autoscale, and waveform math make for very fast test development and execution. A wide range of vertical sensitivity (1 mV/div to 5 V/div), a full function attenuator, and 8-bit vertical resolution provide ample amplitude freedom. All inputs can be switched between 1 M ohms and 50 ohms, and ac or dc coupling. Any two channels can sample simultaneously. Four non-volatile waveform memories can store digitized channel data or data downloaded from a controller. Two independent functions can operate on digitized channels or stored waveforms. The operators available for these functions are plus, minus, times, versus, invert, and only. Routine calibration is performed electronically and only requires connecting the calibration signal provided on the front panel to each input in turn. No external test equipment is required. Calibration data is stored in non-volatile memory. An extensive diagnostic self-test is built into the HP 70703A. This self-test can be initiated, and the test results queried, remotely. Error reporting occurs for both the functional block level and the assembly level to expedite repair, if necessary.
