Mode - Stereo Modulation
Selects the mode for the audio signal. If the internal LF generator is selected as audio
source, the signal is generated according to the selection here. For external signals,
the signal type has to be entered.
"Mono Left"
A mono signal containing the left channel is generated/fed in.
"Mono Right"
A mono signal containing the right channel is generated/fed in.
"Stereo R=L"
A stereo signal with right and left channel is generated/fed in. The
channels have the same frequency and phase.
"Stereo R=-L"
The signal on the left external audio input is used for both channels,
left and right. The right channel is inverted.
"Stereo R!=L"
(External source only)
A stereo signal containing different, independent right and left chan-
nels is fed in. It is possible, for example, to feed a fixed audio fre-
quency to the first channel while a frequency sweep is being per-
formed in the second channel.
Remote command:
[:SOURce]:STEReo:AUDio:MODE on page 410
LF Gen Freq - Stereo Modulation
(Audio source "LF Gen" only)
Sets the frequency of the LF generator signal.
This setting affects all analog modulations which use the LF generator as the internal
modulation source.
Remote command:
(two alias commands are available)
[:SOURce]:STEReo:AUDio[:FREQuency] on page 412
[:SOURce]:LFOutput<ch>:FREQuency on page 349
LF Gen Shape - Stereo Modulation
(Audio source "LF Gen" only)
Selects the shape of the LF generator signal.
This setting affects all analog modulations which use the LF generator as the internal
modulation source.
Remote command:
[:SOURce]:LFOutput:SHAPe on page 357
External R/L Impedance - Stereo Modulation
(External analog audio signal input only)
Selects the input impedance for the external analog audio signal inputs L and R.
Remote command:
[:SOURce]:STEReo:EXTernal:IMPedance on page 413
Preemphasis - Stereo Modulation
Activates and sets the pre-emphasis used for signal generation.
