Modulation Format
Lets you specify the modulation format of the input signal. You can select Auto
Detect to automatically detect the modulation format, or specify modulation format
for your testing.
Remote Command The values of <radio_std> and <options> in these commands depend on the desired Radio
Standard. For available options, see "Radio Standard Keywords & Options" on page 982 below
[:SENSe]:DEMod[:WLAN]:<radio_std>:FORMat <options>
[:SENSe]:DEMod[:WLAN]:<radio_std>:FORMat?
Example Radio Std = 802.11a/g/j/p (OFDM 20 MHz)
:DEM:AG:FORM AUTO
:DEM:AG:FORM?
Radio Std = 802.11b/g (DSSS/CCK/PBCC)
:DEM:BG:FORM AUTO
:DEM:BG:FORM?
Dependencies 4096 QAM is visible only if the license date is equal to or later than 2020.0630. It is enabled only in
11ac, 11ax and 11be and disabled in 802.11a/gj/p,802.11n, 802.11ah and 802.11af. When 4096
QAM is disabled, you cannot select this control and setting 4096QAM through the SCPI command
generates error message “QAM4096 is not a valid value”
If the license version is earlier than 2020.0630, 4096 QAM key is invisible. Setting it through SCPI
generates error message “Command protected; The enum item can be available while the corres-
ponding licenses installed”
