3.7 WLAN MIMO Modulation Analysis Measurement
3.7.7 Frequency
The Freq key opens the Frequency menu, which contains controls that allow you to
control the Frequency and Channel parameters of the instrument.
3.7.7.1 Settings
The Settings Tab contains controls that pertain to the X axis parameters of the
measurement. These parameters control how data on the vertical (X) axis is
displayed and control instrument settings that affect the horizontal axis.
Center Frequency
Sets the frequency that corresponds to the horizontal center of the graticule (when
frequency Scale Type is set to linear). While adjusting the Center Frequency the
Span is held constant, this means that both Start Frequency and Stop Frequency
will change.
Remote
Command
[:SENSe]:FREQuency:CENTer <freq>
[:SENSe]:FREQuency:CENTer?
Example
:FREQ:CENT 50 MHz
:FREQ:CENT UP
changes the center frequency to 150 MHz if you use FREQ:CENT:STEP 100 MHz to set the center
frequency step size to 100 MHz
:FREQ:CENT?
Notes Preset and Max values are dependent on Hardware Options
If no terminator (e.g., MHz) is sent the terminator Hz is used. If a terminator with unit other than
Frequency is used, an invalid suffix error message is generated.
Preset Depends on instrument maximum frequency, mode, measurement, and selected input
State Saved Saved in instrument state
Min Depends on instrument maximum frequency, mode, measurement, and selected input
Max Depends on instrument maximum frequency, mode, measurement, and selected input
Center Frequency Segment1
This key is only available when radio standard is 802.11ac/ax 80+80MHz.
This parameter sets the center frequency of Segment 1.
Note that the SCPI command will set this center frequency even if radio standard is
NOT 802.11ac/ax 80+80MHz.
