•
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
The level can be measured any time.
•
NaN is output as #110 in the PACKed format
•
To ensure that for the two traces the same number of points is output, the two queries have to be
one directly behind the other in the same command line (eg TRACE? MTRACE;TRACE? ITRACE).
Example:
TRACe? MTRACE -> 23.4, -2500, 18.5, 1500
The following is valid for the IFPAN trace:
Output of the spectrum data. If there are no data available then a NaN (Not a Number) will be output.
The output format of the IFPAN trace depends on the settings made by command FORMat:DATA.
ASCii -> normal ASCII output:
• level in dB µ V
PACKed -> <Definite Length Block>:
• level in 1/10 dB µ V (2 bytes)
The following is valid for the suppress trace:
List of frequencies contained in the trace. The suppress-trace output format is defined, according to the
relevant setting, through command FORMat:DATA:
ASCii ->Normal ASCII output:
•
list of frequencies in Hz
PACKed -> <Definite Length Block>
•
list of frequencies in Hz, 4 bytes per frequency
Example:
TRACE? SSTART -> 123475000, 118000000, 98550000
4052.2000.02
no k- factor defined on this frequency
