Time Base Accuracy
When module’s internal clock is selected
Same as the reference clock accuracy of the measuring station (
±
100 ppm for 707001/
707002)
When FFT time base (selectable only on the WE Control API (sold separately,
model: 707741) is selected
±
50 ppm
Trigger Source
Input signal (including input signals from other digitizer modules that are linked) or the
bus trigger signal (BUSTRG1/BUSTRG2) of the measuring station
Bus Trigger (BUSTRG1/BUSTRG2) Signal Output Source
The trigger detected from the input signal can be output

)
Trigger Type
Edge trigger, state trigger, and combination trigger (AND/OR of the input signal)
Amount of Pretrigger
Set in the range from 0 to (the record length – 2)
Sensor Connection Test Function
Checks the opened or shortened condition of the sensor (only when acceleration
sensors are connected)
*1 The typical value is a representative or standard value. It is not a warranted value.
*2 The full scale value is the measurement range between 0 and the positive full scale value.
