R&S ESU
Receiver mode
For reasons of compatibility with the ESIB test receiver, the data structure of the
status information is designed for 4 traces. However, only 3 traces can be acti-
vated and transferred.
SINGle is possible only as a query for single measurements in the receiver mode (bargraph). The
values of all activated detectors are transferred separated by commas in the following order: POS,
NEG, QPE, AVER, CAV, RMS, CRMS. For inactive detectors, the value and the comma are omitted at
the position(s) in question.
PHOLD returns the peakhold value or values of the bargraph measurements with the associated
frequencies. (DISP:BARG:PHOL ON).
SCAN is only possible in form of a query during scan measurements. The number of transmitted
measurement results depends on the scan settings.
FORMAT REAL,32 is to be used as format setting for binary transmission.
Structure of transmitted data:
– 4 byte: trace status: bit 0 to 9 subscan; bit 10: last block of subscan; Bit 11: last block of last subscan
of scan; Bit 12: last of all blocks (for multiple scans after the last scan)
– 4 bytes:number n of the transmitted measurement results of a trace
– 4 byte:trace1 active (0/1)
– 4 byte:trace2 active (0/1)
– 4 byte:trace3 active (0/1)
– n*4 bytes:measurement results of trace 1 if trace 1 is active
– n*4 bytes:measurement results of trace 2 if trace 2 is active
– n*4 bytes:measurement results of trace 3 if trace 3 is active
– n*1 byte:status information per measurement result:
bit 2: overrange trace1 to trace 3;
STATus is only possible in form of a query during scan measurements. 1 byte status information per
measurement result is transmitted:
bit 2: overrange trace1 to trace 3;
FINAL1, FINAL2 and FINAL3 are only possible in form of a query. The final measurement values
are transmitted.
TRACe<1|2>:COPY TRACE1| TRACE2| TRACE3 , TRACE1| TRACE2| TRACE3
This command copies data from one trace to another. The second operand describes the source, the
first operand the destination of the data to be copied.
The associated measurement window is selected with the numeric suffix of TRACe<1|2>.
Example:
"TRAC:COPY TRACE3,TRACE1"
Characteristics: *RST value: -
SCPI: conform
Mode: R, A
This command is an event and therefore has no query and no *RST value.
