Keysight-Agilent 5353A-011

The 5353A Channel C Plug-in consists of a third input to the 5345A Counter (sold separately). When the plug-in 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 the plug-in offers is the ability to count a specific group of events while ignoring others.
