Remote-Control Commands IEEE 802.11 (a/b/g)
58 Operating Manual 1171.5283.12 ─ 18
[:SOURce<hw>]:BB:WLAN:STATe <State>
Activates the standard and deactivates all the other digital standards and digital modu-
lation modes in the same path.
Parameters:
<State> 0 | 1 | OFF | ON
*RST:
0
Example: SOURce1:BB:WLAN:STATe ON
Manual operation: See " State " on page 22
[:SOURce<hw>]:BB:WLAN:TDWindowing:STATe <State>
The command activates/deactivates the time domain windowing. Time domain window-
ing is a method to influence the spectral characteristics of the signal, which is not stipu-
lated by the standard. However, it does not replace oversampling and subsequent sig-
nal filtering. The command is only available for physical layer mode OFDM
(
SOURce:BB:WLAN:MODE OFDM
).
Parameters:
<State> 0 | 1 | OFF | ON
*RST:
OFF
Example: BB:WLAN:TDW:STAT OFF
deactivates the time domain windowing.
Manual operation: See " Time Domain Windowing Active " on page 33
[:SOURce<hw>]:BB:WLAN:TTIMe <Ttime>
The command sets the transition time. The transition time defines the overlap range of
two OFDM symbols when time domain windowing is active. At a setting of 100 ns, one
sample overlaps. This command is only available in physical layer mode OFDM
(
SOURce:BB:WLAN:MODE OFDM
) and with active time domain windowing
(
SOURce:BB:WLAN:TDWindowing:STATe ON
).
Parameters:
<Ttime> float
Range:
0 to 1E-6
*RST: 100E-9
Example: BB:WLAN:TTIM 10 ns
sets a transition time of 10 ns.
Manual operation: See " Transition Time " on page 33
