Displaying Acquired Data
Speed Interval
(
RPM
,
%
, or
NA
, as specified by the
Spacing
setting) – If applicable,
specifies the speed interval (in RPM or % of RPM) used when FFT spectra are calculated
from the recording.
Time Interval
(
sec
or
NA
, as specified by the
Spacing
setting) – If applicable, specifies
the time interval (in seconds) used when FFT spectra are calculated from the recording.
Display Units
(
Accel (g), Accel (m/s
2
), Vel (mm/s), Vel (ips), Disp (mils), Disp (
µ
m)
) –
If necessary, allows integration of the recorded signal to specified measurement units
for display purposes.
Detection
– (
RMS
,
Peak
,
PkPk
) – Specifies Detection type for display purposes.
Lines
–
Specify the FFT lines of resolution, typically 400 lines. Note that higher
resolution settings cause longer delays before waterfall plot display.
X-Axis
– (
Hz
,
CPM
, or
Orders
) – Specify the plot’s frequency / x-axis units. Determines
units for subsequent
Freq Range
and
LF Cutoff
settings.
Freq Range (Hz)
– Specify the plot’s frequency / x-axis range.
LF Cutoff (Hz)
– From the drop down list, specify a cut-off frequency to filter low
frequency noise from the waterfall plot’s displayed spectra.
Waterfall Plot Display

After setting
Waterfall Setup
options, press the
Display
function button to process
spectral data and display the
Waterfall Display Setup
menu.
The larger the acquired data .wav file, the longer the processing
time required.
