----------------------External Power Control-----------------------------------------------------------------------------
EXTERNAL POWER
CONTROL STATE
Switch for activating or deactivating the external power control mechanism of
all enhanced channels.
In the OFF state, the following menu parameters are not effective:
POWER UP RANGE,
POWER DOWN RANGE,
POWER STEP,
IEC/IEEE-bus command :SOUR:W3GP:MST:ENH:EPOW:STAT
ON
POWER STEP
Step width (0.25 to 6.0 dB) by which – with the external power control
mechanism switched on – the channel powers of the activated enhanced
channels in the timeslot grid are increased or decreased within the set
dynamic range.
IEC/IEEE-bus command :SOUR:W3GP:MST:ENH:EPOW:STEP
1.0
POWER UP RANGE
Dynamic range (0 to 30 dB) in which – with the external power control
mechanism switched on – the channel powers of all the activated enhanced
channels can be increased. The value POWER UP RANGE can be changed by
POWER STEP. If the dynamic range is exceeded, the warning "MAX. POWER
UP REACHED” is displayed.
The resulting external power control dynamic range (= POWER UP RANGE –
POWER DOWN RANGE) must not exceed 30 dB. For this reason, the
POWER UP RANGE is limited as a function of the POWER DOWN RANGE.
IEC/IEEE-bus command
:SOUR:W3GP:MST:ENH:EPOW:RANG:UP 10.0
POWER DOWN
RANGE
Dynamic range (0 to 30 dB) in which – with the external power control
mechanism switched on – the channel powers of all the activated enhanced
channels can be decreased. The value POWER DOWN RANGE can be
changed by POWER STEP. If the dynamic range is underranged, the warning
"MIN. POWER DOWN REACHED" is displayed.
The resulting external power control dynamic range (= POWER UP RANGE –
POWER DOWN RANGE) must not exceed 30 dB. For this reason, the
POWER DOWN RANGE is limited as a function of the POWER UP RANGE.
IEC/IEEE-bus command
:SOUR:W3GP:MST:ENH:EPOW:RANG:DOWN 10.0
