Exits the fast Fourier transform (FFT)
measurement and FFT settings.
Turns the percent AM function on or
Off.
Returns the percent of amplitude
modulation (AM).
Changes the spectrum analyzer’s sweep
mode to single sweep mode (if
necessary), and then performs a fast
Fourier transform
(FIT)
on trace A.
Returns the status of the spectrum
analyzer’s
FFT
measurement functions.
Sets the FFT stop frequency of the
FFT
measurement.
Turns off the current measurement,
erases the display, and then displays the
menu accessed by (MEAS/USER].
Specifies the distance (in dB) from the
signal peak for the N dB points
measurement (NDBPNT).
Turns on or off the N dB points
measurement.

Returns the bandwidth measured by the

Performs the occupied bandwidth
measurement using the value for
occupied bandwidth percent (OBWPCT).
Specifies the percent of total power that
is to be used in calculating the occupied
bandwidth (OBW).
Turns on or off the percent AM
measurement.
PCTAMR
Returns the percent AM measured by
the percent AM measurement (PCTAM).

Computes the bandwidth around the
trace center, which includes signals
whose total power is a specified
percentage of the total trace signal
power.
Turns on or off the third-order
intermodulation
(TOI)
measurement.
TOIR
Returns the highest third-order
intermodulation product measured by
the third-order intermodulation
measurement (TOI).
AODE
MODE SPEC’IRUH
AHALYZER
Returns a “0” if the mode of operation
is spectrum analysis. A number other
than “0”
is
returned if the operating
mode (also called “personality”) is other
than spectrum analysis.
