In the case of an external clock source (selection
ARB:CLOCk:SOURce EXTernal
)
the clock for the external source must be entered with this command.
Parameters:
<Clock> float
Increment: 0.001
Example: BB:ARB:CLOC:SOUR INT
selects the internal clock source for generating waveforms.
BB:ARB:CLOC 0.5 MHz
sets the clock rate to 0.5 MHz.
Manual operation: See "Clock Frequency" on page 376
[:SOURce<hw>]:BB:ARBitrary:CLOCk:MODE <Mode>
The command enters the type of externally supplied clock (
:BB:ARB:CLOCk:SOURce
EXTernal
). When MSAMple is used, a multiple of the sample clock is supplied via the
CLOCK connector and the sample clock is derived internally from this. The multiplier is
entered with the command
:BB:ARB:CLOCk:MULTiplier
.
Parameters:
<Mode> SAMPle | MSAMple
*RST:
SAMPle
Example: BB:ARB:CLOC:MODE SAMP
selects clock type "Sample", i.e. the supplied clock is a sample
clock.
Manual operation: See "Clock Mode" on page 390
[:SOURce<hw>]:BB:ARBitrary:CLOCk:MULTiplier <Multiplier>
The command specifies the multiplier for clock type "Multiple Samples"
(
:BB:ARB:CLOCk:MODE MSAM
) in the case of an external clock source.
Parameters:
<Multiplier> integer
Range:
1 to 64
*RST: 4
Example: BB:ARB:CLOC:SOUR EXT
selects the external clock source. The clock is supplied via the
CLOCK connector.
BB:ARB:CLOC:MODE MSAM
selects clock type Multiple Samples, i.e. the supplied clock has a
rate which is a multiple of the sample rate.
BB:ARB:CLOC:MULT 12
The multiplier for the external clock rate is 12.
Manual operation: See "Sample Clock Multiplier" on page 390
