Programming Command Cross Reference
Programming Command Versus Front Panel Key
OR Sets the origin.
OUTPUT Allows the spectrum analyzer to send data to other devices on
the GPIB.
PA Moves the pen to a vector location on the spectrum analyzer
screen relative to the reference coordinates (0,0).
PD Instructs the spectrum analyzer to plot vectors on the spectrum
analyzer screen until a PU command is received.
PDA Sums the probability distribution of amplitude in the
destination trace with the amplitude distribution function of
the source trace.
PDF Increments an element of the destination trace whenever the
corresponding element of the source trace exceeds a threshold.
PEAKS Sorts signal peaks by frequency or amplitude, stores the results
in the destination trace, and returns the number of peaks
found.
PR Moves the pen to a new plot location on the spectrum analyzer
screen relative to the current coordinates in display units.
PU Instructs the spectrum analyzer not to plot vectors on the
spectrum analyzer screen until a PD command is received.
RELHPIB Releases spectrum analyzer control of the GPIB.
REPEAT
UNTIL
Forms a looping construct.
RETURN Stops the operation of a user-defined command and returns
program operation to the point where the user-defined function
was called.
RMS Returns the root mean square value of the trace in
measurement units.
SADD Adds a limit-line segment.
SDEL Deletes the limit-line segment.
SDON Indicates that the limit-line segment is done.
SEDI Edits the limit-line segment.
SENTER Enters the limit-line segment into the limit-line table.
SETDATE Sets the date of the real-time clock.
SETTIME Sets the time of the real-time clock.
SHOWMENU Shows menu.
SKYCLR Clears user softkey.
SKYDEF Defines user softkey.
SMOOTH Smooths the trace according to the number of points specified
for the running average.
SQR Places the square root of the source into the destination.
STDEV Returns the standard deviation of the trace amplitude in
measurement units.
SUB Subtracts source 2 from source 1, point by point, and sends the
difference to the destination.
