– <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

8.8.1 Setting the power unit
The
UNIT
subsystem contains commands for setting up the power unit.
UNIT:POWer <unit>
Sets the output unit for the measured power values.
Parameters:
<unit> DBM | W | DBUV
