<Numerator>, <Denominator>, <Offset>, <SweepType>
Defines the port-specific frequency for frequency-converting measurements. The port
frequency is either a range (for frequency sweeps) or a CW frequency (for power, time
and "CW Mode" sweeps).
Note:
The frequency formula is applied even if the analyzer returns an error message,
because the frequency is outside the allowed range.
Suffix:
<Ch>
.
Channel number
<PhyPt>
Test port number of the analyzer
Parameters:
<Numerator>
Parameters of the frequency formula. The port frequency f
p
is
calculated according to f
p
= <Numerator>/<Denominator> * f
b
+
<Offset> where f
b
represents the channel base frequency
(parameter
SWEep
). For parameters
CW
or
FIXed
, f
b
= 0.
Note:
The <Offset> parameter also includes the "Offset Ratio" in
manual control.
Range:
The converted frequency or frequency range must
be within the analyzer's frequency range, depend-
ing on the instrument model. In addition the
<Numerator> values are rounded to positive or neg-
ative integer numbers; zero is not allowed.
*RST:
The default frequency/frequency range corresponds
to the sweep range or CW frequency of the ana-
lyzer, i.e. <Numerator> = <Denominator> = 1, <Off-
set> = 0 Hz.
Default unit: 1
<Denominator>
See above, <Numerator>
Range:
The converted frequency or frequency range must
be within the analyzer's frequency range, depend-
ing on the instrument model. In addition the
<Denominator> values are rounded to positive inte-
ger numbers; zero is not allowed.
*RST:
1
Default unit: 1
<Offset>
See above, <Numerator>
Range:
The converted frequency or frequency range must
be within the analyzer's frequency range, depend-
ing on the instrument model. In addition the <Off-
set> values are rounded to (positive or negative)
multiples of 1 Hz.
*RST:
0
Default unit: Hz
