Program Timing
The previous program example does not measure with the new
analyzer settings as depicted by the data-invalid indicator "*" in the
upper right corner. To obtain valid trace information, the trace must be
updated with the TS command. Here is the program again, corrected to
include the TS command. E
XAMPLE. Change the measurement range,
then update trace information.
Connect the calibrator signal to the analyzer 50Ω INPUT before
performing this example.
10 CLEAR 718
20 OUTPUT 718;"IP;SNGLS;"
Initialize analyzer.
30 OUTPUT 718;"SP 1MHZ;CF 300MHZ;"
