Average
:
Avg. Type, Avg. No., Overlap, Preview, Start Freq.
AverageType:
Select Off, Linear,
Exponential, Peak Hold or Time.
Note: Time average performs averaging in
the time domain. If the time signal is not
syncronized by an appropriate triggering, the
result will be incorrect.
Average Number
: Select 1,3,5, 10, 20, 30,
50, or 100, 200, 500, 1,000, 2,000, or 5,000.
Overlap
: Select 0%, 25%, 50%, 75%,
Maximum. Note- when maximum is selected,
the Fieldpaq will perform the maximum
overlap available at the time of measurement. This is done automatically, as the
Fieldpaq is a real time instrument and will allocate as many resources as possible
based on the setup parameters.
Preview
: Select either On or Off. When preview is on, the FFT program will
pause and show you the acquired time domain data for your preview. You will
then have to accept or reject it. For example, this is usually used for an impact
test. It enables you to preview the time waveform and screen out the bad data,
which might be caused by a double-hitting or overloading signal.
Overload/ Rejection
: Select On or Off. When Overload/Rejection is on, data
that is overloaded will automatically be
rejected during an averaging process.
Trigger
:
Type, Level, Slope, Delay %
Type
: Select Off, Ext, Ext, Ch 1, Ch 2, Ch 3 or
Ch 4 to specify the desired input channel for
triggering functionality. The trigger function
is used to control the timing of data
acquisition. If the trigger function is on, the
system will always wait for a trigger signal to
acquire data on the selected input channel.
