. [:DATA] <trace_name>
Query of trace data
Error message:
If the trace name is unknown, an error -141,"Invalid character data" will be generated.
Parameters:
<trace_name> name of desired trace as <Character Data> (MTRACE, ITRACE, IFPAN or
SSTART, SSTOP)
Result:
The following is valid for MTRACE:
Output of measured values of all sensor functions switched on. If no function is switched on, NaN (Not a
Number) is output.
If FREQ:OFFS is switched on, only the offset value is output. If VOLT:AC is switched on, only the level
value is output. If FREQ:OFFS and VOLT:AC are switched on, first the level value and then the offset
value are output.
The INF value 9.9E37 is entered into the result buffers MTRACE and ITRACE for MSCAN, FSCAN or
DSCAN to identify the range limit.
The following is valid for ITRACE:
Output of channel number and receive frequency.
Depending on the setting, the output format is defined by the FORMat:DATA command:
ASCii -> normal ASCII output:
• level in dBuV
• offset in Hz signed
• field strength in dBµV/m with sign
• channel number without unit
• frequency in Hz
PACKed -> <Definite Length Block>: (see "Block data" on page 11)
• level in 1/10 dBuV (2 bytes)
• offset in Hz (4 bytes)
• field strength in 1/10 dBuV (2 bytes)
• channel number (2 bytes)
• frequency in Hz (4 bytes)
Note:
The sensor function FSTRength will only provide results if the SW option EB200FS is fitted. Also see
Annex H.
Notes:
• INF (range limit flag) will be coded in the PACKed format as follows:
INF level = 2000
INF offset = 10000000
INF FSTR = 0x7FFF
INF freq = 0
INF channel = 0
