Command Syntax
SOURce:SYNChronize[:Input]:RANGe <nr2>
Description
Allows configuration of how much the synchronization engine is able
to deviate from the AFX programmed frequency. This helps to keep
the waveform frequency under control, even if the external source is
not present all the time. The synchronization engine is limited to
frequencies of FSE/- FRANGE.
Parameters
Range in Hz
Parameter Format
<nr2>
Example
SOUR:SYNC:RANG 5.0
Query Format
SOURce:SYNChronize[:Input]:RANGe?
Returned Data Format
<nr2>
Query Example
SOUR:SYNC:RANGe?
10.000
Command Syntax
SOURce:SYNChronize[:Input]:SOURce <cr>
Description
This command selects either the external sync TTL (1) or the internal
AC line sync (0) mode. The internal AC sync signal is derived from the
power sources three phase L-L voltages so a phase adjustment for
Phase A output will be needed using the
SOURce:SYNChronize[:Input]:PHASEshift command.
Parameters
[ 0 |AC | 1 | TTL ]
Parameter Format
<cr>
Example
SOUR:SYNC:SOUR TTL
Query Format
SOURce:SYNChronize[:Input]:SOURce?
Returned Data Format
<cr>
Query Example
SOUR:SYNC:SOUR?
1
Command Syntax
SOURce:SYNChronize[:Input]:SPeed <nr2>
Description
Allows accelerating the speed of the internal synchronization engine
(PLL) in case the external sync source is not constant and presents
periodic or continuous changes. A slower speed improves the stability
of the waveform frequency, so it is recommended to keep use the
smallest possible speed values.
Parameters
Speed (multiplier value)
Parameter Format

Range is 1.000 ~ 10.000
