n Return Value
1 or omitted Returns a variable-length (1 + 6 * Spurs – up to 1201 entries) comma-separated list containing detailed
information in the following format:
Number of spurs in following list (Integer)
[Repeat the following for each spur]
–
Spur #
–
Range # Spur was located (Integer)
–
Frequency of Spur (Hz, Float64)
–
Amplitude of Spur (dBm, Float32)
–
Absolute Limit (dBm, Float32)
–
Pass or Fail (1|0, Boolean)
2 – 21 (Average
Trace)
Regardless of the Trace selection, returns a comma-separated list of the average trace data for the
selected range (where range number = n – 1) using Detector 1. If selected range is not active, SCPI_
NAN is returned for each trace data element
22 Returns the number of spurs found for the selected Measured Trace
23 – 42 (Average
Trace)
Regardless of the Trace selection, returns a comma-separated list of the average trace data for the
selected range (where range number = n – 22) using Detector 2. If selected range is not active or
Detector 2 selection is off, SCPI_NAN is returned for each trace data element
43 – 62
(Maximum Hold
Trace)
Regardless of the Trace selection, returns a comma-separated list of the maximum hold trace data for
the selected range (where range number = n – 42) using Detector 1. If selected range is not active,
SCPI_NAN is returned for each trace data element
63 – 82
(Minimum Hold
Trace)
Regardless of the Trace selection, returns a comma-separated list of the minimum hold trace data for
the selected range (where range number = n – 62) using Detector 1. If selected range is not active,
SCPI_NAN is returned for each trace data element
83-102 Reserved
103-122 Reserved
123-142
(Clear/Write
Trace)
Regardless of the Trace selection, returns a comma-separated list of the clear/write trace data for the
selected range (where range number = n – 122) using Detector 1. If selected range is not active,
SCPI_NAN is returned for each trace data element
143-162
(Clear/Write
Trace)
Regardless of the Trace selection, returns a comma-separated list of the clear/write trace data for the
selected range (where range number = n – 142) using Detector 2. If selected range is not active or
Detector 2 selection is off, SCPI_NAN is returned for each trace data element
163-182 (Trace
1)
Returns a comma-separated list of the trace data of Trace 1 for the selected range (where range
number = n – 162). If selected range is not active, SCPI_NAN is returned for each trace data element
183-202 (Trace
2)
Returns a comma-separated list of the trace data of Trace 2 for the selected range (where range
number = n – 182). If selected range is not active, SCPI_NAN is returned for each trace data element
203-222 (Trace
3)
Returns a comma-separated list of the trace data of Trace 3 for the selected range (where range
number = n – 202). If selected range is not active, SCPI_NAN is returned for each trace data element
223 Returns "Marker Table" on page 1358 data as a series of comma separated values in the following form:
