1693 RLC Digibridge
1.2 General Description
1.2.1 1693 RLC Digibridge Overview
The basic features of the 1693 are provided on the
vertical front panel. These include the keypad, dis-
play, and the power OK/OFF button. The set of four
bnc connectors for connection to the test fixture is
supplied on the front panel, but can be relocated to
the rear if that is preferred. The display-panel and
keyboard indicators serve to inform and guide the
operator in manipulating the simple controls, or to
indicate that remote control is in effect.
The 1693 instrument also stands on a table or bench,
where the bail provided under its front edge can be
used to tilt it back for operator convenience . This
model goes particularly well in a rack , with its ver-
tical front panel and cable connection (from either
front or rear) to a suitable test fixture. The sturdy
metal cabinet is durably finished, in keeping with the
long-life circuitry inside. Glass-epoxy circuit boards
interconnect and support high-quality components to
assure years of dependable performance.
Adaptability to any common ac power line is assured
by the removable power cord and the convenient line
voltage switch. Safety is enhanced by the fused iso-
lating power transformer and the 3-wire connection.
