WLAN User Interface IEEE 802.11 (a/b/g)
26 Operating Manual 1171.5283.12 ─ 18
Sequence Length
Sets the sequence length of the signal in number of frames. A (physical layer) frame
consists of a PPDU burst including the subsequent idle time.
Remote command:
[:SOURce<hw>]:BB:WLAN:SLENgth
on page 56
Idle time
(based on standard chip rate)
(This feature is available for Framed Mode only).
Sets the idle time, i.e. the time between two PPDU bursts. Idle time is given in µs; the
packets can also be joined to each other directly with idle time
0. Please note that the
idle time refers to the chip rate as defined in the standard (11 Mcps for 802.11b/g CCK/
PBCC and 20 Mcps for 802.11a/g OFDM). Only at this chip rate does the idle period
correspond exactly to the time set. If the chip rate is doubled, for instance, the real idle
time is halved.
Remote command:
[:SOURce<hw>]:BB:WLAN:ITIMe

PPDU Configuration
(This feature is available for Framed Mode only).
Calls the menu for configuration of the PPDU. The menu differs for the physical layer
modes.
The menu is described in Chapter 3.2, "PPDU/Sequence Configuration" , on page 27.
Remote command:
n.a.
Sequence Configuration
(This feature is available for Unframed Mode only).
Calls the menu for configuration of the signal in unframed modes.
The menu is described in Chapter 3.2, "PPDU/Sequence Configuration" , on page 27.
Remote command:
n.a.
Filter/Clipping
Calls the menu for setting the filter parameters and the clipping. The current setting is
displayed next to the button.
The menu is described in section Chapter 3.5, "Filter/Clipping Settings" , on page 38.
Remote command:
n.a.
Trigger - Marker
Calls the menu for selecting the trigger source, for configuring the marker signals and
for setting the time delay of an external trigger signal (see
Chapter 3.6, "Trigger/
Marker/Clock Settings" , on page 40).
The currently selected trigger source is displayed to the right of the button.
