58 Configuration Parameters
IEPE Buffer Power and
Signal Detection
Parameters Use these parameters to configure the IEPE and buffer power options and to
determine the measurement performed on the input signal to produce the
overall value.
IEPE Buffer Power and Signal Detection Parameters
Parameter Name Description Values/Comments
Controls whether to provide standard accelerometer
(IEPE) power to the transducer. The IEPE Power is
configurable in channel pairs: Channels 1 and 2,
Channels 3 and 4, and Channels 5 and 6.
Important: When mixing transducer types, such as
IEPE accelerometers and non-contact sensors,
non-IEPE powered transducers cannot be in a
channel-pair with IEPE transducers. For example, if
you plan to use a single accelerometer and a single
non-contact sensor, wire the accelerometer to
channel 1 and enable IEPE Power Channels 1 and
2. Wire the non-contact sensor to channel 3 and
disable IEPE Power Channels 3 and 4. See page
49 for wiring details.
Signal Detection The measurement (or calculation) performed on the
input signal to produce the Overall Value. See Data
Parameters on page 74.
• RMS - The Overall Value is the root mean squared
(RMS) signal level of the input signal.
• Calculated Peak - The Overall Value is the
measured RMS value multiplied by the square root
of two (1.4142).
• Calculated Peak-to-Peak - The Overall Value is
the measured RMS value multiplied by two times
the square root of two (2.8284).
• True Peak - The Overall Value is the output of a
peak detector applied to the input signal.
• True Peak-to-Peak - The Overall Value is the
output of a peak-to-peak detector applied to the
input signal.
Options: RMS

Note: This parameter setting applies
to all six channels.
