Description

The PRL-350TTL-NIM-C001 is a ready-to-use, dual-channel comparator module derived from the PRL-350TTL-NIM, and modified for low-current applications. 

Each unit is supplied with a ±8.5 V AC/DC Adapter and housed in an attractive 1.3 x 2.9 x 3.9-in. extruded aluminum enclosure.

For the PRL-350TTL-NIM, very slight output waveform distortion and rise time degradation will occur when an unused complementary output is not terminated




.

(0° C ≤ TA ≤ 35° C)*

Unless otherwise specified, dynamic measurements are made with all outputs terminated into 50 Ω.

(1) If the switch is set to the center position (0 V threshold) a non-driven channel will oscillate and induce jitter in the driven channel. Connect any output to any input to stop the oscillation.

(2) 10%-90% for TTL.

For the PRL-350TTL-NIM-C001, very slight output waveform distortion and rise time degradation will occur when an unused complementary output is not terminated. For optimum performance, however, all outputs should be terminated.

(3) In order to reduce jitter near fMAX, terminate the non-driven input into 50 Ω when the input voltage is less than 20 mVPP.
