<Numerator>,
<Denominator>, <Offset>, <SweepType>
Defines the receiver frequency of a power meter used for frequency-converting mea-
surements. The receiver frequency is either a range (for frequency sweeps) or a CW
frequency (for power, time and CW Mode sweeps). The receiver frequency is valid for
all ports.
<Numerator>, <Denominator> and <Offset> are parameters of the frequency formula.
The receiver frequency f
r
is calculated according to
f
r
= <Numerator>/<Denominator> * f
b
+ <Offset>
where f
b
represents the channel base frequency (parameter
SWEep
). For parameters
CW
or
FIXed
, f
b
= 0.
<Numerator>, <Denominator> and <Offset> values are rounded to positive or negative
integer numbers; zero is not allowed.
Note:
●
The default frequency or frequency range corresponds to the sweep range or CW
frequency of the analyzer.
●
The <Offset> parameter also includes the "Offset Ratio" in manual control.
●
The converted frequency or frequency range must be within the power meter's
receiver frequency range. Nevertheless, the frequency formula is applied even if
the analyzer returns an error message, because the frequency is outside the
allowed range.

<SweepType>
CW | FIXed | SWEep
SWEep - the full formula is applied. For frequency sweeps, the
command defines a sweep range.
CW | FIXed - the reduced formula with f
b
= 0 is applied; the com-
mand defines a fixed frequency.
