FUNDamental
Measurement of the fundamental signal (non frequency-convert-
ing mode). This selection cancels all port-specific frequency and
power settings (see example).
ARBitrary
Frequency conversion mode (arbitrary port frequencies). This
mode is automatically activated when a port-specific frequency
is defined.
MIXer
Scalar mixer mode. The mixer mode is configured using the
[SENSe<Ch>:]FREQuency:CONVersion:MIXer... com-
mands.
IMODulation
Intermodulation measurement mode, configured using the
[SENSe<Ch>:]FREQuency:IMODulation... commands.
*RST:
FUNDamental
Example: See SOURce<Ch>:FREQuency<PhyPt>:CONVersion:
ARBitrary:IFRequency
Manual operation: See "Reset" on page 534
[SENSe<Ch>:]FREQuency:CONVersion:ARBitrary <Numerator>, <Denominator>,
<Offset>, <SweepType>
Unused command.
The R&S ZNB/ZNBT doesn't allow to set a separate receiver frequency for Frequency
Conversion Measurements. Use SOURce<Ch>:FREQuency<PhyPt>:CONVersion:
ARBitrary:IFRequency to define the port-specific frequency (range or CW).
[SENSe<Ch>:]FREQuency:CONVersion:ARBitrary:PMETer<Pmtr> <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.
