Option Description
Off The analyzer does not use the CSI 2140 Four-Channel Input Adapter or external
multiplexer. The analyzer acquires all data through the same channel, and you
must manually start and accept each measurement.
On The CSI 2140 Four-Channel Input Adapter controls software that switches
between channels. The analyzer acquires all data on channels A to D, and you must
specify the input channel for each measurement point. You must manually start
and accept each measurement reading. The default is On.
Auto The CSI 2140 Four-Channel Input Adapter controls software switching between
channels. The analyzer acquires all data on channels A to D, and you must specify
the input channel for each measurement point. After you start the first reading,
the analyzer acquires and accepts each measurement when the value is good for
three consecutive averages (stable). The analyzer advances to the next step.
Ext An external multiplexer is used. The analyzer acquires all data on channels 1 to 8,
and you must specify the input channel for each measurement. You must
manually start and accept each measurement reading.

9.4.6 Set up the bandwidth
You can set the bandwidth (tracking filter) to attenuate all frequency components except
the desired 1x turning speed peak. A narrow bandwidth filter, with a low numerical value,
attenuates frequency components close to the equipment turning speed. A narrow filter
requires more time to take a measurement. The bandwidth of the filter is equal to:
(the frequency of the equipment turning speed peak) X (the bandwidth parameter)
For example, if the equipment speed is 1,800 RPM and the bandwidth parameter is 0.10,
the filter bandwidth is 180 RPM or +/- 90 RPM. Frequency components are not attenuated
between 1,710 and1,890 RPM.
Note
This is available only in Advanced Balance mode.
