SQR
Returns the root mean square value of
the trace in measurement units.
Places the square root of the source
into
the destination.
STDEV
SUB
Returns the standard deviation of the
trace amplitude

measurement units.
Subtracts source 2 from source 1, point
by point, and sends the difference to
the destination.

WlRKERS
Allows you to specify the channel
bandwidth used for the adjacent
channel power (ACP), adjacent channel
power extended (ACPE), and channel
power (CHP) measurements.
Changes the spectrum analyzer’s sweep
mode to continuous sweep, and then
performs the previous power
measurement (occupied bandwidth,
adjacent channel, or channel power) at
the end of every sweep.
Performs the adjacent channel power
extended measurement.
Computes and displays an adjacent
channel power (ACP) graph.
Determines if the spectrum analyzer
settine
used for the adjacent channel
power (ACP), adjacent channel power
extended (ACPE), channel power (CHP),
or occupied bandwidth (OBW)
measurement are set manually or
automatically.
Changes the spectrum analyzer’s sweep
mode to single sweep, performs a take
sweep (TS), and then performs the
previous power measurement.
Allows you to specify the frequency
spacing between channels.
Performs the channel power
measurement.
Performs a discrete fast Fourier
transform on the source trace array and
stores the result in the destination array.
Performs a fast Fourier transform
(FFT)
on the signal on which the marker is
placed.
Indicates if the FFT results are valid.
Performs a fast Fourier transform
(FFT)
continuously on the current signal.
Activates the FFT markers and displays
the FFT annotation on the spectrum
1
analyzer display.
