1090.3123.12 E-6 4.18
Source
Sel
ection of the modulation source. The sources cannot be used
simultaneously.
Off The stereo modulation is witched off.
Ext L, R Selection of the L and R inputs for external analog
modulation signals.
Ext S/P DIF Selection of the S/P DIF input for the external digital
modulation signal.
LF Gen The modulation signal is generated by the internal
LF generator.
IEC/IEEE-bus command :SOUR:STER:SOUR LREX; STAT ON
Mode
Selection of the operating mode.
L Audio signal only in the left-hand channel.
R Audio signal only in the right-hand channel.
L=R Audio signals of same frequency and phase in both channels.
L=-R Audio signal of same frequency but opposite phase in both
channels.
LPR Different and independent audio signals in both channels (not
possible with internal LF generator).
IEC/IEEE-bus command :SOUR:STER:MODE LEQR
LFGen Freq
Input value of the frequency of the LF generator.
IEC/IEEE-bus command :SOUR:STER:INT:FREQ 1kHz
Ext L,R Impedances
Selection of the input impedances of the analog audio inputs l and R. Both
input impedances are switched simultaneously.
IEC/IEEE-bus command :SOUR:STER:EXT:IMP 100kOhm
Preemphasis
Selection of the preemphasis.
Off Preemphasis switched off.
50 µs Preemphasis 50 µs
75 µs Preemphasis 75 µs
IEC/IEEE-bus command :SOUR:STER:PRE 50us
Pilot State
Switching on/off the pilot tone.
On Pilot tone switched on
Off Pilot tone switched off
IEC/IEEE-bus command :SOUR:STER:PIL:STAT ON
Pilot Deviation
Input value of the frequency deviation of the pilot tone.
IEC/IEEE-bus command :SOUR:STER:PIL:DEV 6.75kHz
Pilot Phase
Input value of the phase of the pilot tone (with respect to to 38 kHz subcarrier). .
IEC/IEEE-bus command :SOUR:STER:PIL:PHAS 0 DEG
