3.6 Modulation Analysis Measurement
Note that the SCPI command will set this center frequency even if radio standard is
NOT 802.11ac/ax 80+80MHz.
Remote
Command
[:SENSe]:FREQuency:CENTer:SEGMent1 <freq>
[:SENSe]:FREQuency:CENTer:SEGMent1?
Example
:FREQ:CENTer:SEGM1 5.53 GHz
:FREQ:CENTer:SEGM1?
Notes For an 80+80 MHz channel, the Segment 1 will be the lower or upper segment. The center frequency of
this Segment1 is independent from the center frequency of Segment2
SEM measurement will rearrange the Segment 1 and Segment 2 based on their center frequency, and
will generate a “setting conflict” error message if the spacing between the two segments is less than 80
MHz
Preset 5.21 GHz
State Saved Saved in instrument state
Min Depends on instrument minimum center frequency
Same as Center Frequency
Max Depends on instrument maximum center frequency
Same as Center Frequency
Center Frequency Segment2
This key is only available when radio standard is 802.11ac/ax 80+80MHz and when
the active measurement is SEM, CHP or Modulation Analysis.
This parameter sets the center frequency of Segment 2.
Note that the SCPI command will set this center frequency even if radio standard is
NOT 802.11ac/ax 80+80MHz.
Remote
Command
[:SENSe]:FREQuency:CENTer:SEGMent2 <freq>
[:SENSe]:FREQuency:CENTer:SEGMent2?
Example

:FREQ:CENTer:SEGM2?
Notes For an 80+80 MHz channel, the Segment 2 will be the lower or upper segment. The center frequency of
this Segment2 is independent from the center frequency of Segment1
SEM measurement will rearrange the Segment 1 and Segment 2 based on their center frequency, and
will generate a “setting conflict” error message if the spacing between the two segments is less than 80
MHz
Preset 5.45 GHz
State Saved Saved in instrument state
Min Depends on instrument minimum center frequency
