The HP 8991A peak power analyzer provides complete and accurate characterization of complex pulsed signals. It is capable of performing seven automatic timing measurements (rise time, fall time, pulse width, PRI. PRF, duty cycle, and delay) and five automatic power measurements (peak power, average power, pulse top/base amplitude, and overshoot) with pushbutton ease. Front-panel operation is intuitive and straightforward. Data entries can be typed in or made with the front panel knob; automatic measurements are made with simple keystrokes. The HP 8991A offers two sensor channels plus two external triggering/oscilloscope channels, allowing the simultaneous measurement of modulating signals and detected power envelopes. Powerful measurement and display routines put you in control of your most demanding pulse applications. Measurement statistics, high-speed/ high-sensitivity triggering, amplitude and time markers, dual-timebase windowing, measurement limit test, waveform storage, and waveform math. Specifications.
