is lit up: IEPE power supply for the corresponding reference input (REF 1 to
REF 8) activated in the software
2 REF 1 analog input (BNC jack)
Analog voltage input for the reference signal. You can also connect a sensor
equipped with an integrated amplifier to this input, according to the IEPE concept,
also known as ICP® (4 mA / 24 V). Activating or deactivating the IEPE power
supply is described in your software manual.
REF 2 to REF 8 analog inputs (BNC jacks)
There are up to seven additional analog voltage inputs are available for reference
signals.
3 SYNC TTL output (BNC jack)
TTL output for the SYNC signal of the function generator
4 TRIG IN TTL input (BNC jack)
TTL input for an external trigger signal
5 AUX OUT TTL output (BNC jack)
TTL output for special applications (programmable via Visual Basic® Engine)
6 AUX IN TTL input (BNC jack)
TTL input for special applications and also to connect the PSV-A-430 acoustic
gate unit (programmable via Visual Basic® Engine)
