8 2321-20 WAVEFORM MODULE
Example of using a few the Model 2321-20 to perform
parallel simultaneous measurement
To take parallel simultaneous measurement, connect 2321-20 (A)
[TRIG. CH1 OUT] to output trigger signal and 2321-20 (B) and
2321-20 (C) [TRIG. CH1 IN] to input trigger as shown in the dia-
gram. For 2321-20 (B) and 2321-20 (C) for inputting external trig-
ger, set the external trigger of the start trigger to [ON Fall].
When the trigger condition for CH1 of 2321-20 (A) is met and the
trigger is activated, trigger output terminal the signal for [TRIG.
CH1 OUT] will change. The [TRIG. CH1 IN] of CH1 of 2321-20 (B)
and 2321-20 (C) will receive the pulse signal of 2321-20 (A) and
start the measurement.
Output signal Open collector output Active LOW
Output Time Waveform retrieval / output time specification (range within
1 to 255 s)/PC Reset by application
