(Reference Output query) Returns the present value of the reference when editing the
output (error mode). If not editing the output using the INCR command, the return is 0
(0E+00). The reference value is set with the OUT, NEWREF or MULT commands. To
determine which quantity is being edited, use the EDIT? and OUT? commands.
Response: <reference value>
Example: REFOUT? returns 0E+00
Returns 0 when the output is not being edited.
Example: REFOUT? returns 2.500000E−01
Returns .250 when the output is being edited and the reference is, for example, 250 mV.

(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: Phase with optional multiplier and DEG unit
Example: REFPHASE 1.5 DEG (1.5 degrees)
On either Calibrator, set the phase of the primary channel to lead the sync pulse by 1.5
degrees.

(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: (float) Phase in degrees
Example: REFPHASE? returns 1.50E+00 (1.5 degrees)
