Data List Management
Calls the "Data List Management" menu. This menu is used to create and edit a data list.
All data lists are stored as files with the predefined file extension *.dm_iqd. The file
name and the directory they are stored in are user-definable.
Note: All data lists are generated and edited by means of the SOURce:BB:DM subsystem
commands. Files containing data lists usually end with *.dm_iqd. The data lists are
selected as a data source for a specific function in the individual subsystems of the digital
standard.
Example: Creating and editing the data list:
SOUR:BB:DM:DLIS:SEL "GPS"
SOUR:BB:DM:DLIS:DATA 1,1,0,1,0,1,0,1,1,1,1,0,0,0
SOUR:BB:DM:DLIS:DATA:APP 1,1,0,1,0,1,0,1,1,1,1,0,0
Set to default RF and Level
(For instruments with RF output only)
Calls the default RF and level settings for GPS signals.
The frequency is set to the GPS carrier frequency selected by parameter "RF Band" (L1
of 1.57542 GHz respectivelly L2 of 1.2276 GHz) and the output level is set to –115.0
dBm.
Note: To avoid any damage to connected receivers, the user must ensure that the signal
level used is not too high. A downstream attenuator pad must be connected to generate
output levels below -145 dBm.

Generate Waveform File…
(R&S WinIQSIM2 only)
Calls the "Generate Waveform" menu. This menu is used to store the current GPS signal
as ARB signal in a waveform file.
This file can be loaded in the "ARB" menu and processed as multicarrier or multisegment
signal.
