2.3.1.1. – CHANNEL Ports
The vibration CHANNEL inputs will accept acceleration, velocity, or displacement sensor
signals. All vibration CHANNEL inputs are six-pin MS socket connectors. Any of the channels
may be specified in the SETUP function as the input for a single plane balance job. The six-pin
connector enables the analyzer to provide sensor power as required to the sensor being used.
2.3.1.2. – TACH Ports
The “TACH” inputs are three-pin female receptacle connectors. Both Gen II analyzers will
accept either a raw tachometer speed reference signal or a Transistor-Transistor Logic (TTL)
level speed signal. Power (+12V) is provided on one pin of the tachometer connector to power
optical speed sensors such as the Phototach or LASETACH

. The tach inputs available for each
analyzer version are outlined in the table below.
