Rockwell Automation 1440-VSE02-01RA XM-122 gSE Vibration Module - Manual (Page 75)

Publication GMSI10-UM013D-EN-P - May 2010
Configuration Parameters 65
Spectrum/Waveform Parameters
There are two instances of the spectrum/waveform parameters, one for each
channel. Use these parameters to set up the conventional spectrum and
waveform measurements.
TIP
Use the gSE Parameters to configure the gSE spectrum
measurements.
Spectrum/Waveform Parameters
Parameter Name Description Values/Comments
FMAX Sets the maximum frequency or order for the
spectrum measurement.
Note: The Sampling Mode parameter determines
whether the measurement is frequency or order.
Note: You can enter any FMAX. The
module will automatically use the next
higher supported maximum frequency.
Supported maximum frequencies in
Hz:
Single integrated/ Double
Non-integrated Integrated
10 to 5000 10 to 5000
6250 6250
7500 9375
8000 18750
9375
10000
12500
15000
18750
20000
Number of Lines The number of lines or bins in the spectrum
measurement. This determines the frequency or
order resolution of the spectrum measurement.
Note: When Sampling Mode is set to
"Synchronous," the Number of Lines must be
evenly divisible by the FMAX value (no remainder).
See example table below. Note that the maximum
number of orders possible is equal to the Number of
Lines.
Options: 100
