Each channel must be programmed to accept a REFERENCE signal from either the external or the optional
internal.
When the button is pressed, for CH. 1, the Reference Source is selectable
between “INT” (Optional
Internal Reference as source),
“FRT” (External reference source through the front panel) or “BCK” (External
reference source through the J1 connector. For CH. 2, the Reference Source is selectable
between “INT”
(Optional Internal Reference as source) or
“EXT” (external reference source). NOTE: CH. 2 External reference
source is only applicable through the J1 connector.
V
REF

When an external reference is specified, the anticipated V
REF
must be entered by pressing the V
REF
button and entering the appropriate voltage. This needs to be done in order to let the Simulator set a
transformation ratio (or proportion between R
EF
voltage input and output voltage V
LL
) when the
“RATIOMETRIC”
output mode is selected.
Internal Reference Setup
If internal reference option is installed in the 5330A, press the
Internal Ref
button that will bring
up the sub-screens for controlling the reference:
