Agilent / HP 81104A Pulse Pattern Generator, 80 MHz

When the Agilent 81104A Pulse Pattern Generator Mainframe is combined with one or two Agilent 81105A output modules (single and/or dual channel) builds on the performance of the 81101A and is also backward-compatible. Each Agilent 81104A single-channel Pulse Pattern Generator requires one Agilent 81105A output module. For the dual-channel configuration, two Agilent 81105A output modules are required. If two Agilent 81105A Output modules are available, the outputs can be added. This allows elaborate pulse shapes for simulating glitches, testing clock-recovery circuits or generating 3- or 4-level codes. 

The Agilent 81104A  produces all the standard pulses and digital patterns needed to test current logic technologies. By using the internal channel addition feature provided by the optional second channel, multi-level and multi-timing signals can be produced. The Agilent 81104A  Pulse Pattern Generator provides high quality signals and flexibility that meet virtually all application needs.
