Attenuation
Specifies the settings for the attenuator. This field is only editable if the "Auto Lvl"
option is deactivated. If the "Auto Lvl" option is activated, the RF attenuator setting is
coupled to the reference level setting.
Remote command:
INPut:ATTenuation on page 177
Sample Rate
Specifies the sample rate used for IQ measurements.
For IEEE 802.11a, p: the Input Sample Rate can be chosen continuously.
For IEEE 802.11n: 20 MHz, 40 MHz, 80 MHz*
For IEEE 802.11ac. 20 MHz, 40 MHz, 80 MHz*, 160 MHz*
*) requires bandwidth extension option

Meas Range (IEEE 802.11b, g)
Defines the measurement range for the peak vector error.
"All Symbols"
Peak Error Vector results are calculated over the complete PPDU
"PSDU only"
Peak Error Vector results are calculated over the PSDU only
