IFPAN
If there are no data available then a NaN (Not a Number) will be output.
1. “VOLTage:AC"
Suppress Traces
Output the list of frequencies contained in the trace.
1. Frequency
Remark:
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
NINF (no measurement possible) will be coded in the PACKed format as
follows:
NINF offset = 10000000-1
NINF FSTR = 0x7FFE
NINF AM = 0x7FFE
NINF FM = 0x7FFF FFFE
NINF PM = 0x7FFE
NINF BW = 0x7FFF FFFE
NaN is output as #110 in the PACKed format
To ensure that for the two traces MTRACE and ITRACE the same number of
points is output, the two queries have to be one directly behind the other on
the same command line (e.g. “TRACE? MTRACE;TRACE? ITRACE”).
Example:
TRACe? MTRACE -> 23.4, -2500, 18.5, 1500
TRACE? SSTART -> 123475000, 118000000, 98550000, 0, 0, 0, .........
