Port selection
The port selection lists in the upper part of the dialog contain all analyzer ports or
external generators which can provide the RF signal (left side) and local oscillator (LO)
signals (lower signal(s)). The fractional numbers in the rectangles indicate the fre-
quency conversion settings from the "Frequency" tab. The receive port for the IF signal
is selected on the right side of the diagram.
Note:
are part of the RF connection configuration, opera-
is
not
supported. In this case only external generators
can be used as local oscillators.
Generators must be configured explicitly in the "External Generators" dialog before
they appear in the list. Use
to open it. "None" means that the input signal
at LO (if available) is not controlled by the analyzer.
Remote command:
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:RFPort
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:IFPort
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:LOPort<Stg>
Frequency tab
The "Frequency" tab controls the frequency of the RF and the LO signal(s) and the
analyzer (IF signal) frequency.
The table in the "Frequency" tab contains the following columns:
●
"Type" specifies how the frequency for each signal is defined. One of the mixer
input and output signals is at the analyzer's channel base frequency ("Base Freq";
the signal is swept if a frequency sweep is active; it is at fixed frequency (CW) for
the other sweep types). One or two signals are at "Fixed" frequencies. The last fre-
quency or frequency range is calculated automatically ("Auto"), depending of the
other dialog settings.
●
"Port" assigns the input and output ports to the predefined port frequency types.
The table contains one or two LO ports, depending on whether the "2nd Mixer" is
selected.
●
"Start/CW" defines the start frequencies or fixed frequencies at the ports with
"Base Freq" or "Fixed" frequency type and overwrites the "STIMULUS" settings.
For frequency sweeps, the "Base Freq" is the frequency sweep range.
●
"Stop" defines the stop value of the frequency sweep range with "Base Freq" type
(for frequency sweeps only).
