●
4 byte, bit 0 represents the state of trace 4 (0/1)
Note:
If more than 4 traces are active, the state of trace 5 and 6 is indicated by an addi-
tional bit (bit 8) in the UINT32 field of trace 1 and 2.
●
n*4 byte, measurement results for trace 1; only if trace 1 is active
●
n*4 byte, measurement results for trace 2; only if trace 2 is active
●
n*4 byte, measurement results for trace 3; only if trace 3 is active
●
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 (
).
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.
