File
Instrument Functions: A - L
Example: MMEM:STOR:STAT 1,’C:\mystate.sta’ saves the current instrument
state to the specified file name. The .sta extension is required.
*SAV saves the current instrument state to a file name REGxxx, where xxx
= the register number. The available register numbers are 0 to 127.
MMEM:STOR:SCR ‘C:\myscreen.gif’ The file must have a .gif file
extension. The specified file extension determines which file format the
instrument will use to save the image. Only
Bitmap is available (not Reverse
Bitmap).
MMEM:STOR:TRAC TRACE3,’C:\mytrace.trc’ Saves trace 3 to the trace +
state file C:\MYTRACE.TRC
MMEM:STOR:CORR ANT, ‘A:TEST1.AMP’ saves the current antenna
correction to the specified file name. The .amp extension is required.
MMEM:STOR:LIM LLINE2,’C:mylimit.lim’ saves the current limit line
two data set to the specified file name. The .lim extension is required.
MMEM:STOR:RES ‘A:ACP.CSV’ saves the current ACP measurement
results to the specified file name. The .csv extension is required.
