The 81110A is a used Pulse Generator from Agilent. A pulse generator is a piece of electronic test equipment that engineers use to generate rectangular pulses. An electromagnetic pulse generator is best for digital, not analog, circuits. The Keysight (Agilent) 81110A with one or two Keysight (Agilent) 81111A output modules is a single/dual-channel 165 MHz Pulse Pattern Generator. In comparison to the Keysight (Agilent) 81104A, the 81110A offers the same performance on a wider frequency range. Modul PXI switch microunde DC-26.5GHz Agilent M9156C pret, The Agilent / HP 81110A 330/165 MHz Pulse/Pattern Generator generates all standard pulses, digital patterns and multi-level waveforms needed to test all current logic technologies (such as TTL, CMOS, ECL, PECL, LVDS, GTL) and other digital designs up to 330 MHz.
