–
<parameter>
U
must be specified for uncertainty data files. If a parameter is not specified, S
is implicitly assumed and as a result an error message is triggered.
–
<format>
This value is ignored in uncertainty measurement files. The entry is therefore
irrelevant.
–
<R n>
R is optional and followed by the reference impedance in
Ω
. If no entry is
made, R50 is implicitly assumed.
The option line therefore reads:
# [HZ | KHZ | MHZ | GHZ] U [MA | DB | RI] [R 50]
.
●
Measurement frequencies
The measurement frequencies are listed in ascending order and are specified as
follows:
f
i
unc[s
11
( f
i
)]
unc[s
21
( f
i
)]
unc[s
12
( f
i
)]
unc[s
22
( f
i
)]
where
f
i
is the i-th frequency and
unc[ s
jk
( f
i
)]
is the uncertainty of the S-parameters
that is forwarded as follows:
–
As extended absolute uncertainty ( k = 2 ) for the magnitude of reflection
parameters s
11
and s
22
–
As extended uncertainties ( k = 2 ) in dB for the magnitude of transmission
parameters s
21
and s
12

Comments
Any line starting with an exclamation mark (
!
) is interpreted as a comment line.

Querying measurement results
After the measurement, you can query the measurement results with a command from
the
FETCh
subsystem.
Remote commands:
FETCh<Sensor>:ARRay[:POWer][:AVG]?
.......................................................................... 75
FETCh<Sensor>[:SCALar][:POWer][:AVG]?
........................................................................75
FETCh<Sensor>:ARRay[:POWer][:AVG]?
Queries the last valid measurement result of a measurement with enabled data buffer
mode.
Usage:
Query only
FETCh<Sensor>[:SCALar][:POWer][:AVG]?
Queries the last valid measurement result of the measurand that was configured
before.
Usage:
