Returns 0 when the output is not being edited.
Example:
Returns .250 when the output is being edited and the reference is, for example, 250 mV.
REFPHASE
(Reference Phase command) If two Calibrators are synchronized using 10 MHz
IN/OUT, sets the phase difference between the primary channel on the Calibrator relative
to the sync pulse on the 10 MHz IN or OUT terminal. The primary channel is the
NORMAL, AUX, or 20A terminal for single outputs and the NORMAL terminal for ac
power and ac dual voltage outputs. The sync pulse on the 10 MHz IN or OUT terminal is
the phase reference. The set range is 0.00 to ±180.00 degress, with + for a leading phase
difference and − for a lagging phase difference.
Parameter:
Example:
On either Calibrator, set the phase of the primary channel to lead the sync pulse by 1.5
degrees.
REFPHASE?
(Reference Phase query) If two Calibrators are synchronized using 10 MHz IN/OUT,
returns the phase difference between the primary channel on the Calibrator and the sync
pulse on the 10 MHz IN or OUT terminal.
Response:
Example:
REFPHASE_D
(Reference Phase Default command) If two Calibrators are synchronized using 10 MHz
IN/OUT, sets the power-up and reset default phase difference between the primary
channel on the Calibrator relative to the sync pulse on the 10 MHz IN or OUT terminal.
The primary channel is the NORMAL, AUX, or 20A terminal for single outputs and the
NORMAL terminal for ac power and ac dual voltage outputs. The sync pulse on the
10 MHz IN or OUT terminal is the phase reference. The set range is 0.00 to
±180.00 degrees, with + for a leading phase difference and − for a lagging phase
difference.
Parameter:
Example
On either Calibrator, set the power-up and reset default phase of the primary channel to
lead the sync pulse by 1.5 degrees.
REFPHASE_D?
x
(Reference Phase Default query) If two Calibrators are synchronized using 10 MHz
IN/OUT, returns the power-up and reset default phase difference between the primary
channel on the Calibrator and the sync pulse on the 10 MHz IN or OUT terminal.
