Parameters:
<Source> INTernal | EXTernal
INTernal
The CW signal in the control list is used for the control.
The internal signal can be output on one of the user interfaces.
EXTernal
The control signal on the CW pin of the AUX I/Q connector is
used.
*RST:
INTernal
Example: BB:DM:SWIT INT
the CW signal in the control list is used for the control.
Manual operation: See "Source Mod - CW" on page 348
[:SOURce<hw>]:BB:DM:SWITching:STATe <State>

[:SOURce<hw>]:BB:DM:CLOCk:MODE <Mode>
The command enters the type of externally supplied clock (
:BB:DM:CLOCk:SOURce
EXTernal
).
The bit clock and the symbol clock differ only in the case of modulations that have
more than two states, i.e. that require more than one bit for encoding each state. When
MSYMbol
is used, a multiple of the symbol clock is supplied via the CLOCK connector
and the symbol clock is derived internally from this. The multiplier is entered with the
command
:BB:DM:CLOCk:MULTiplier
.
It is not possible to select
BIT
and
MSYMbol
in the case of an external serial or exter-
nal parallel data source (
SOUR:BB:DM:SOUR SER
and
PAR
).
Parameters:
<Mode> SYMBol | MSYMbol | BIT
