2.2.12 Spurious Emissions The spurious emissions measurement identifies and determines the power level of
spurious emissions in certain frequency bands. For more information see “Meas Setup
(Spurious Emissions)” on page 213.

n Results Returned
n=1 (or not
specified) Returns a variable-length list of values containing detailed spur
information. The total number of data values returned is (1 + 6x spurs),
where x is the number of spurs identified. You can have up to 121 data
entries if you have the maximum 20 spurs identified. The values returned
are in the following order:
1. Number of spurs in items 2 through 6 in this list
[Repeat the following for each spur]
2. Spur number
3. Range number in which spur was located (integer)
4. Frequency of spur (Hz)
5. Amplitude of spur (dBm)
6. Absolute limit (dBm)
7. Pass or Fail (1|0)
n=2 through 21 Returns trace data values for the selected frequency range (where range
number = n − 1). If the selected range is not active, then 9.91E37 is
returned for each non-active trace data element.
n=22 Returns the number of spurs found.
n=23 through 42 Returns a comma-separated list of the trace data for the selected range
(where range number = n - 22). If selected range is not active, SCPI_NAN
is returned for each trace data element (where SCPI_NAN = 9.91E37).
