Description
When the peak table is turned on, the spectrum analyzer screen displays two windows. The
upper window displays trace A, with the signal peaks of trace A identified and numbered
(the peaks are numbered according to their frequency or amplitude, see “PKSORT” for more
information). The lower window displays the peak table. The peak table displays the following
information about the on-screen signal peaks: the number of the peak, the frequency of the
peak, and the amplitude of the peak. A signal must be equal to or exceed the peak excursion
to be considered a peak. (See “MKPX” for more information about the peak excursion.) While
the peak table is turned on, the frequency and amplitude of each peak is updated at the
end of every sweep (PKTBL command uses the ONEOS command to update the peak table
information).
See “PKRES” for information about how to get the information in the peak table remotely.
You can execute the PKTBL command two different ways. You can either execute the PKTBL
command directly (for example, “PKTBL 1; ‘I) or use the MOV command to move the 1 or 0 into
the PKTBL command (for example, “MOV PKTBL , 1; ‘I). If you use the MOV command, no text is
displayed in the active function area during command execution.
Restrictions
Turning on the peak table turns off the following functions: windows display mode (WINON),
N dB point measurement (NDBPNT), the FFT menu measurements (FFTAUTO, FFTCONTS,
FFI’SNGLS), gate utility functions (GDRVUTIL), TO1 measurement (TOI), marker table (MKTBL),
percent AM (PCTAM), peak zoom (PKZOOM), and power menu measurements (ACP, ACPE, CHP,
and OBW).
You should turn off the peak table (set PKTBL to 0) when you are done with the peak table.
