Programming
Program Timing
The next example processes trace information with a marker command,
MKPK HI (marker peak highest), which selects the highest amplitude
level in the trace. Because the program changes the measurement
range, the trace information must be updated with TS before MKPK HI
is executed. E
XAMPLE. Use TS to update trace information before using
the marker commands.
Connect the calibrator signal to the analyzer INPUT 50Ω before
performing this example.
