ProDAQ 3808
-
The ProDAQ 3808 function card, an enhanced version of the ProDAQ 3806 counter/timer function card, is designed to operate in one of three modes: pulse counter, frequency meter, or time interval counter. In the pulse counter and frequency measurement modes, users can process incoming signals of up to 25 MHz on each of the six channels. A time interval counter range is divided into six sub-ranges, covering times from 40 ns to 20000 s with a maximum resolution of 10 ns. For pulse-width measurements, the same ranges apply.

Power Limiters
-
Keysight's power limiters provide the best broadband input protection from excess RF power, DC transients and ESD, for a variety of RF and microwave instruments and components. For example, the input circuitry of spectrum analyzers, network analyzers, frequency counters or amplifiers can be protected from unintentional inputs up to 5 watts average power. At even greater power levels, failure mode for the limiter is either an open circuit or a short circuit to ground, thereby protecting the instrument from damage.
