cPCI/PXI - P635 8-channel 100 kHz Frequency Counter View Datasheet Request Ordering Information   ABOUT P635 The P635 is a single-width, 3U, PXI bus module with eight frequency measurement channels. This counter module can be used to monitor a variety of pulse sources. Moreover, its unique circuitry allows the monitoring of a wide range of frequencies without changing any module settings. TTL inputs are provided as well as differential input circuits, with filtering and hysteresis to provide high noise immunity. The switching threshold is programmable. The input voltage should be at least twice the threshold voltage for noise immunity. AC or DC coupling of the differential inputs is programmable on a per-channel basis.

Features Contains eight frequency counter channels Frequency range from 0.06 Hz to 100 kHz Differential and TTL input provided Differential input range ±20 mV to ±20V Programmable AC/DC differential inputs Programmable observation window :1ms to 1.024 sec Precision time base (±1 ppm, 10 deg.
