15 Power Control Measurement
FREQ Channel
Source Numerator, Source Denominator and Power Sweep.
Preset
See table above
State Saved
Saved in instrument state.
Min
–79.999995 MHz, unless Source Mode is set to Tracking, in which case it is limited by the
minimum frequency of the Source
Max
See table above. Basically instrument maximum frequency – 5 Hz. Note that, if the Source Mode is
set to Tracking, the effective instrument maximum frequency may be limited by the source maximum
frequency.
If the knob or step keys are being used, also depends on the value of the other three interdependent
parameters Span, Start Frequency and Stop Frequency
Initial S/W Revision
Prior to A.02.00

Ext Mix Center Freq
SCPI command for specifying the External Mixer Center Frequency. This command will set the Center
Frequency to be used when the External Mixer is selected, even if the External Mixer input is not the input
which is selected at the time the command is sent. Note that the Center Freq function in the Frequency
menu on the front panel always applies to the currently selected input.
Scope
Meas Global
Remote Command
[:SENSe]:FREQuency:EMIXer:CENTer <freq>
[:SENSe]:FREQuency:EMIXer:CENTer?
Example
:FREQ:EMIX:CENT 60 GHz
:FREQ:EMIX:CENT?
Notes
This command is the same in all modes, but the parameter is Measurement Global. So the value is
independent in each mode and common across all the measurements in the mode.
Couplings
When returning to External Mixing after having been switched to one of the other inputs (e.g., RF), you
will come back into the settings that you had when you left External Mixing. So you will come back
to the band you were in with the Center Frequency that you had. However, Span is not an input-
dependent parameter, therefore you will bring the span over from the other input. Therefore, the
analyzer comes back with the span from the previous input, limited as necessary by the current mixer
setup.
Preset
When a Mode Preset is performed while in External Mixing, the Start frequency of the current Mode
is set to the nominal Min Freq of the lowest harmonic range in the Harmonic Table for the current
mixer setup. Similarly, the Stop frequency of the current Mode is set to the nominal Max Freq of the
highest harmonic range in the Harmonic Table. The Center Freq thus presets to the point
arithmetically equidistant from these two frequencies.
If the current measurement has a limited Span available to it, and cannot achieve the Span shown in
the table (Span=Stop Freq – Start Freq), the analyzer uses the maximum Span the measurement
allows, and still sets the Center Freq to the midpoint of the Start and Stop Freq values in the
Harmonic Table.
