●
n*4 byte, measurement results for trace 4; only if trace 4 is active
●
n*4 byte, measurement results for trace 5; only if trace 5 is active
●
n*4 byte, measurement results for trace 6; only if trace 6 is active
●
n*1 byte, status information for each measurement result
➙
bit 2 represents overrange for trace 1 to trace 6
The data is always returned in binary format (
FORM REAL,32
).
Note that the
SCAN
parameter only works while the scan is actually running.
Example:
TRAC? SCAN
Querying results for a peak search
The SCPI parameters
PLIST1
| ... |
PLIST6
returns the results of a peak search for a
particular trace or detector (1 to 6).
Each result is made up out of three values:
●
4 byte, frequency
●
4 byte, absolute level
●
4 byte, Delta between absolute level and limit line value at corresponding fre-
quency
If no limit line is active, the delta value is set to 0.0
The trace has to be active for the command to work.
Example:
TRAC? PLIST3
Querying results for the final measurement
The SCPI parameters
FINAL1
| ... |
FINAL6
return the results of the final measure-
ment for a particular trace or detector (1 to 6).
Each result is made up out of three values:
●
4 byte, frequency
●
4 byte, absolute level
●
4 byte, Delta between absolute level and limit line value at corresponding fre-
quency
If no limit line is active, the delta value is set to 0.0
The trace has to be active for the command to work.
Querying the status of the measurement results
The SCPI parameter
STATUS
returns the status information for each measurement
result. Thus, the number of returned values depends on the number of measurement
results
n . For each measurement result, the parameter queries 1 byte of status infor-
mation.
