n Return Value
n/a n/a
n/a name of current measurement: "APD"
n/a n/a (selects the APD measurement in Meas Preset state)
n/a n/a (selects the APD measurement without affecting settings)
not Returns a comma separated list containing detailed information in
specified the following format:
or n=1
• Number of Peak Signal in the following list (integer)
[Repeat the following for each peak]
• Signal#
• Trace# where peak is located
• Frequency
• Disturbance Level (E meas)
• Probability of Time (ρ meas)
• Disturbance Level to Limit Delta
• Probability to Limit Delta
2 Returns a series of 1024 points Trace 1 data as a list of x,y pairs. x
is the Probability of Time, while y is the disturbance level. The y-
values are in the current X Axis Unit of the instrument.
When querying trace data, it is best if the analyzer is not sweeping
during the query. Therefore, it is good to be in Single Sweep, or
Update=Off when querying trace data from the instrument.
3 Returns a series of 1024 points Trace 2 data as a series of x,y
pairs.
4 Returns a series of 1024 points Trace 3 data as a series of x,y
pairs.
