V
LL
(Voltage Line-to-Line) Output Select
Each channel must be set to a desired output voltage (V
LL
). When the
button is pressed, enter the
desired output voltage (V
LL
) for each channel.
Then specify either “FIXED” or “RATIOMETRIC” mode. (See next
illustration)

Output select & Fixed/Ratiometric mode
Fixed
/
Ratiometric (Voltage output mode select)
Each channel can be set for “FIXED” or “RATIOMETRIC” output. When the button is pressed, the
output mode will toggle between “FIXED” and “RATIOMETRIC”. When set for “FIXED”, the output voltage (V
LL
)
will remain constant at the set V
LL
voltage. When set for “RATIOMETRIC”, the output signal voltage (V
LL
) will vary
directly with changes in the applied reference voltage.
ANGLE set
Each channel can be programmed to various angles. When the button is pressed, enter the desired
angle using the touch screen, mouse, or incremental knob.

Angle Set
Alternatively, when the “ANGLE SET” icon is pressed, the unit will respond to the “Increment / Setup” knob
and will step the output angle according to the value set up in the “Delta screen” panel.
PHASE Offset
Each channel can be programmed to a specific phase shift between the output and the reference. Typically, this
is utilized to closely match the phase difference exhibited by a true Synchro.
When the button is pressed, enter the required phase shift between the output signal and reference
source. Press the
“Set” button to complete.
