Note
Operations which are invalid when the output is ON are also invalid when
Deferred mode is active, even if the output is OFF. For example you cannot
change range in Deferred mode even if the output is OFF.
[SOURce]:OUTPut:RCLock(?) <dnpd>
This command allows a signal derived from the internal master oscillator to be routed to the
rear panel.
The following values are accepted:
0.0 - disable reference out signal.
10e6 - set reference out to 10 MHz.
20e6 - set reference out to 20 MHz.
The default value is 0.0 (i.e. reference out signal is off).
SOURce]:OUTPut:RAMP(?) <CPD>{ FAST | SLOW }
When the output is enabled, the output level is not instantaneously applied at its full
amplitude; instead it ramps up to this value over a short period of time. This normally takes
10 ms; it is possible to set this time to 2 s to provide a “soft start” for systems which might
trip the internal over-voltage/current detectors, if the default rate of change is too fast.
Select whether the output ramp up time is 10 ms or 2 s.
FAST - Ramp up within 10 ms,
SLOW - Ramp up within 2 s.
The default value is FAST.
Note: This command is depreciated in favour of OUTPut:RAMP:TIME
[SOURce]:OUTPut:RAMP:TIME(?) <dnpd>
When the output is enabled, the output level is not instantaneously applied at its full
amplitude; instead it ramps up to this value over a short period of time. This normally takes
10 ms. This command allows the setting of this time between 0 and 10 seconds to provide a
soft start for systems which might trip the internal over-voltage/current detectors, if the
default rate of change is too fast.
The default value is 0.
[SOURce]:OUTPut:VOLTage:NLIMit <CPD>{ LOW | HIGH }
This command allows the neutral phases’ voltage channel range limits to be extended from
33 V to 1008 V.
The parameters are:
LOW - Maximum amplitude is 33 V
HIGH - Maximum amplitude is 1008 V.
The default value is LOW.
Note: The HIGH setting is intended for use when the instrument’s neutral phase is being
used as an independent supply – i.e. not connected in a star or delta configuration. Damage
to the instrument can result if the N-phase voltage Hi is connected to any 6140A Lo
terminal when an amplitude greater than 33 V is selected.
