HP 8082 Pulse Gen

The Agilent / HP 8082A is a 250 MHz dual channel pulse source with variable leading and trailing edge transition times as fast as 1ns. It also has variable pulse frequency, delay, width, offset and amplitude. The normal/complement relationship and the polarity of either output can be reversed. Single pulse, double pulse and square wave operation are available. There are also four trigger modes: Normal Mode. In this mode the 8082A operates as a self-contained pulse source with full control of the pulse parameters from the front panel controls. Ext Trig Mode. In this mode the pulse and trigger output frequencies are determined by the frequency of an externally applied signal. The other pub parameters are varied from the front panel controls. Gate Mode. In this mode a gating signal enables the pulse and trigger outputs. External Width Mode. In this mode the pulse frequency and width are determined by the frequency and width of an externally applied signal. The delay between input and output is fixed. The trigger output is the shaped trigger input signal. ECL OUTPUT: The 8082A has an ECL position on each of its amplitude range switches. When either or both of the switches are set to this position, both 8082A outputs automatically deliver a fixed voltage swing of -0.9V to -1.7V typical (into an open circuit) for driving ECL logic.
