The Frequency Scan measurement is intended to be used for compliance or precompliance EMI
measurement. The display consists of a conventional spectrum graticule display, meters, and signal list at
the bottom.

Returns a comma separated list containing detailed information in
the following format:
• Number of Peak Signal in the following list (integer)
[Repeats the following for each peak]
• Signal#
• Trace# where peak is located
• Frequency
• Amplitude of Detector 1
• Amplitude of Detector 2
• Amplitude of Detector 3
• Detector 1 vs. Limit Delta (A positive value denote a fail point)
• Detector 2 vs. Limit Delta (A positive value denote a fail point)
• Detector 3 vs. Limit Delta (A positive value denote a fail point)
If there is no value of amplitude or detector limit delta in the signal
list, value 9.91e37 ("not a number") will be returned.
This query returns Trace 1 data as a list of x,y pairs. The y-values
are in the current Y Axis Unit of the instrument. The x-axis values
are the values of the trace, in the x-axis scale units of the trace (Hz
for frequency domain traces, seconds for time domain traces).
When querying trace data, it is best if the instrument 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.
Returns Trace 2 data as a series of x,y pairs
Returns Trace 3 data as a series of x,y pairs
