Agilent / HP / Keysight 5353A
5353A CHANNEL C
This Channel C Plug-in consists of a third input to the 5345A Counter.
When this unit counting capability is combined with the mainframe gating capability it becomes quite easy to make frequency sum and frequency difference measurements.
For high speed digital applications, the greatest benefit this unit offers is the ability to count a specific group of events while ignoring others.
