5.2.3.12 User Marker / AUX I/O Settings
The R&S SMJ provides four "USER" interfaces which can be freely assigned a selec-
tion of signals and which can be configured as both inputs and outputs.
The following table gives an overview of the signals that can be applied at the USER
connector.
Table 5-1: USER Connector Signals
Signal Description
"Marker 4" A broad selection of suitable marker signals is offered in the marker
menus of the "Baseband" block. In addition, they can be freely config-
ured in the "Custom Dig Mod > Control List Editor" and "GSM/EDGE >
Slot Marker Editor". The selected markers are activated when switch-
ing on the "Baseband" block. When using markers defined in a control
list ("Marker" = "CList") the related control list must be loaded in addi-
tion ("Custom Dig Mod").
"CW Mode Out" This signal marks the CW mode in which digital modulation ("Custom
Dig Mod") is deactivated and the RF signal is output in unmodulated
form. The CW signal is defined in a control list and activated by load-
ing the control list and setting the "Modulation<-> CW Switching State"
to
On in the "More" submenu.
With standards where it is possible to change between various modu-
lation modes, the signal indicates the active modulation mode (stan-
dard GSM: signal high (1) = modulation mode GMSK and signal low
(0) = modulation mode 8PSK EDGE). In this cases, the signal is gen-
erated automatically when the standard is switched on.
"No Signal (Blank) Marker" This signal marks the blank time in the List mode. The signal is gener-
ated automatically when the list mode is switched on.
