R&S SMB LF Generator and LF Output - Mod Gen Block
1407.0806.32 4.81 E-2
SOUR:LFO:SWE:FREQ:DWEL 10ms
Ext Trigger Input Slope - LF
Sweep
Sets the polarity of the active slope of an applied instrument trigger.
This setting affects the INST TRIG input (BNC connector at the rear of
the instrument).
Positive
The rising edge of the trigger signal is active.
Remote-control command:
SOUR:INP:TRIG:SLOP POS
Negative
The falling edge of the trigger signal is active.
Remote-control command:
SOUR:INP:TRIG:SLOP NEG
LF Output Menu
The LF Output menu is opened in the Mod Gen function block or using the MENU key under Mod
Gen.
The LF Output menu provides access to the configuration of the internal modulation generators. In
addition, the LF output is configured in this menu. The available settings depend on the source selected
and on the installed options.
In the upper section of the menu, the LF output is switched on. The configuration of the internal source
is performed in the lower section of the LF Output menu or in the individual modulation menus of the
Mod block (e.g. Amplitude Modulation menu). These settings affect all modulations which use the same
modulation sources and the LF output.
State - LF Output
Activates/deactivates the LF Output.
The modulation signal is output at the LF output connector at the front
of the instruments.
Remote-control command:
SOUR:LFO:STAT ON
Output Voltage - LF Output
Sets the output voltage of the LF output. The entered value
determines the peak voltage.
Remote-control command:
