Example:
TRAC? TRACE1
The number of results depends on the currently selected number of sweep points. For
each sweep point, the command returns one level value. The unit depends on the
measurement and on the unit you have currently set.
The trace has to be active for the command to work.
Querying bargraph results
The SCPI parameters SINGLE and PHOLD return the results of the bargraph measure-
ment.
SINGLE returns the current bargraph results for each active bargraph detector.
The order of detectors is as shown in the user interface: maximum peak, minimum
peak, quasipeak, average, RMS. Inactive detectors are ignored.
Example:
TRAC? SINGLE
PHOLD returns the bargraph maxhold results for each active bargraph detector.
Each result is made up out of two values:
●
Absolute level
●
Frequency
The order of detectors is as shown in the user interface: maximum peak, minimum
peak, quasipeak, average, RMS. Inactive detectors are ignored.
Example:
TRAC? PHOLD
Querying scan characteristics
The SCPI parameter SCAN returns the scan characteristics while the scan is running.
The amount of returned results depends on the scan settings.
The type of returned data is as follows:
●
4 byte, trace status:
➙ bit 0 to 9 represent the subscan
➙ bit 10 represents the last block of a subscan
➙ bit 11 represents the last block of the last subscan
➙ bit 12 represents the last of all blocks (for multiple scans after the last scan)
●
4 byte, number n of measurement results contained in one trace
●
4 byte, bit 0 represents the state of trace 1 (0/1)
●
4 byte, bit 0 represents the state of trace 2 (0/1)
●
4 byte, bit 0 represents the state of trace 3 (0/1)
