SME LF-Output
1038.6002.02 2.133 E-13
Notes: If LF generator 2 (LFGEN2) is selected as source and
- STEREO operating mode is activated,
the voltage of the LF output depends on the setting of the
wanted and the pilot deviation and cannot be changed in this
menu. The output voltage is 6 dBu (1.55 VRMS at 600 ?) per
40 kHz of set sum deviation. The following is displayed:
VOLTAGE (STEREO) 6dBu / 40 kHz
- one of operating modes VOR, ILS-GS or ILS-LOC is activated,
the input of the output voltage of the LF output is effected
relative to the set sum modulation depth. The following is
displayed, e.g. in the case of VOR modulation:
VOLTAGE (VOR/ILS) per 100% DEPTH 1.000
V
LF SOURCE
Selection of the signal source for the LF output.
IEC bus short command :OUTP2:SOUR 0 (Selection of LF generator 1)
:OUTP2:SOUR 2 (Selection of LF generator 2)
LFGEN1 FREQ
Input value of the frequency of internal modulation generator 1.
IEC bus short command :SOUR0:FREQ 1kHz
LFGEN1 SHAPE
Input value of the signal shape for modulation generator 1. The signal shape of
modulation generator 1 can only be set if two modulation generator options are
fitted.
IEC bus short command :SOUR0:FUNC SIN
LFGEN2 FREQ
Input value of the frequency of internal modulation generator 2. This parameter
is only displayed if a modulation generator option is fitted.
IEC bus short command :SOUR2:FREQ 1kHz
Note: In operating modes Stereo, VOR, ILS... or LF-Sweep the value
indication is replaced by "STEREO", "VOR", "ILS.." or "SWEEP".
LFGEN2 SHAPE
Input value of the signal shape of modulation generator 2. This parameter is
only displayed if a modulation generator option is fitted.
IEC bus short command :SOUR2:FUNC SIN
Notes: - A selection of signal shape NOI in the LF-SWEEP operating
mode automatically leads to this operating mode being aborted.
- In operating modes STEREO, VOR, ILS.. an indication of this
parameter is eliminated. Instead, a selection between STEREO
OUTPUT MPX and PILOT is possible (see below).
STEREO OUTPUT
Selection of the stereo signal at the LF output. This parameter is only displayed
if STEREO modulation is activated.
MPX Output of the complete Stereo multiplex signal.
PILOT Output of the pilot tone.
IEC bus short commands :SOUR:STER:STAT ON;
:OUTP2:SOUR 2;
:OUTP2:SOUR:STER MPX
