553 Operating Manual 1407.6062.32 ─ 08
Example: BB:DM:CLOC:MODE SYMB
selects clock type Symbols, i.e. the supplied clock is a symbol
clock.
[:SOURce<hw>]:BB:DM:CLOCk:MULTiplier <Multiplier>
The command specifies the multiplier for clock type Multiple Symbols
(
BB:DM:CLOCk:MODE MSYM
) in the case of an external clock source.
Parameters:
<Multiplier> float
Range:
1 to 64
Increment: 1
*RST:
4
Example: BB:DM:CLOC:SOUR EXT
selects the external clock source. The clock is supplied via the
CLOCK connector.
BB:DM:CLOC:MODE MSYM
selects clock type Multiple Symbols, i.e. the supplied clock has a
rate which is a multiple of the symbol rate.
BB:DM:CLOC:MULT 12
the multiplier for the external clock rate is 12.
[:SOURce<hw>]:BB:DM:CLOCk:SOURce <Source>
The command selects the source for the digital modulation clock.
Parameters:
<Source> INTernal | EXTernal
INTernal
The internal clock reference is used.
EXTernal
The external clock reference is supplied to the CLOCK connector.
*RST:
INTernal
Example: BB:DM:CLOC:SOUR INT
selects the internal clock reference.
[:SOURce<hw>]:BB:DM:CLOCk:SYNChronization:MODE <Mode>
Selects the synchronization mode
This parameter is used to enable generation of very precise synchronous signal of several
connected R&S SMBVs.
Note : If several instruments are connected, the connecting cables from the master instru-
ment to the slave one and between each two consecutive slave instruments must have
the same length and type. Avoid unnecessary cable length and branching points.
