[SOURce:]ROSCillator
The [SOURce:]ROSCillator subsystem controls the reference oscillator’s
source and indicates the frequency of an external oscillator. The HP
E1340A uses the source and frequency information to generate the
waveform frequency for all waveform shapes.
Subsystem Syntax [SOURce:]
ROSCillator
:FREQuency
:EXTernal <
frequency>
:GATE
:STATe <

:SOURce <

:FREQuency
:EXTernal
[SOURce:]ROSCillator:FREQuency:EXTernal <frequency> indicates to
the HP E1340A the frequency of an external reference oscillator source.
The
SOURce:FREQuency subsystem uses this value to generate the
waveform frequency when
SOURce:ROSCillator:SOURce is set to
EXTernal.

MINimum selects 1 Hz; MAXimum selects 42.94967296 MHz.
Comments • AC amplitude correction can only be made if the current reference
oscillator frequency is 42.94967296 MHz, either internal or external.
CALibration:STATe:AC must be set to OFF when a different external
reference oscillator frequency is selected.
• Indicating an incorrect frequency for an external reference oscillator
will cause incorrect sample rate and waveform frequencies to be
generated by the
SOURce:FREQuency subsystem.
