80+80 MHz Mask (Only for WLAN)

The key “80+80 MHz Mask” is visible only when the license for 802.11 ac format is available, and is

only enabled when the radio standard is 802.11ac (80 MHz + 80 MHz). The mask lines could be drawn

in two different ways, according to the IEEE 802.11ac standard (entry 22.3.18.1) when the key’s value is

“Auto”; or by the user-defined specifications listed in the Offset/Limits menu.

Example: SEM:LIM STD
SEM:LIM?
Notes: You must be in the TD-SCDMA mode to use this command. Use
:INSTrument:SELect to set the mode.
Dependencies: See Couplings
Couplings: When the value of the “Limits” key is Std, the parameters displayed on the
Offset/Limits panel will be modified depending on the carrier power, which
corresponds to the measurement standard of the base station. All the keys
except “Offset”, “Relative Atten”, “Offset Side” and “Limits” displayed on
the “Offset/Limits” panel will be grayed out. All the keys displayed on the
“Limits” panel will be grayed out as well.
When the value of the “Limits” key is Man, all of the previous manual
specifications will be restored, and the keys that were previously grayed out
will be enabled again.
