Delivering clean pulses- even at the maximum frequency of 50 MHz- and timing changes that are free of dropout and other glitches is the HP 81101A programmable pulse generator. The instrument also features fast, variable transition times as well as flexible amplitude and duty cycles. Users can save test settings and program the unit for automated test routines. In addition, settings for the HP81101A can be used on other pulse/pattern generators in the firm's 81100 family.The single-channel instrument generates all of the standard pulses required to test current logic technologies. Timing values can be swept without danger of spurious pulses or dropouts that can cause measurement errors. Other features include a clear graphical display, autoset capability, a help mode, selectable units and load compensation. Frequency accuracy is specified at 0.01%.
