Rear-Panel Connectors
The followingis an overview of rear-panel connectors.
Figure 2-3 shows the 1760--Seriesrear pa nel.

Loop-Through Inputs

HINPUTS A, A1, A2, A3, B, B1, B2,and B3 are passive
loop-through video inputs, compensated for 75 Ω.
The front-panel INPUT switch settings determine
which channel(s) are displayed. Inputs 1, 2, and 3
are designed for component signals. All inputs can
be used with composite signals.
HEXT REF is a 75 Ωcompensated loop-through
synchronization input. Internal or external reference
is selected through the front-panel REF EXT switch;
the LED lights to showwhen external is selected.
The instrument will operate from external referenc es
of composite video or black burst.

Outputs

HPIX OUT is a 75 Ωcompensated out put of the video
signal selectedby the front-panel INPUT switche s.
This signal has bright-up in LINE SELECT mode, and
is usedto drive a picture monitor. PIXOUT strobe is
not present below line 11.
HGBR provides a GBR output for a picture monitor.

Multi-Pin Conne ctors

HREMOTE is a 25-pin subminiature D-type connector
which uses TTL signal or ground closures to provide
remote control of many front-panel functions. For
more information about the remote connector, see
page 2-8 and page B-1.
HRS232 is a 9-pin subminiatureD-type connectorthat
provides a serial interface for remote control.
