AR 10036390, Operating And Service Manual

Page: 21 / 56

All amplifier control functions and status indi-
cations are available remotely in GPIB/IEEE-
488, RS-232, RS-232 Fiber Optic, Ethernet
and USB. The buss interface connectors are
located on the back panel and positive control
of local or remote operation is assured by a
keylock on the front panel of the amplifier.
The 800A3B amplifier is intended for applica-
tions where the load impedance is not neces-
sarily 50 ohms. The selectable output imped-
ance provides the capability to drive loads that
would otherwise cause a high SWR and limit
the delivered power. The impedance matching
transformer uses high-voltage/high-current
vacuum relays so the user can “hot switch”
between impedances without damage.
The Model 800A3B is housed in a cabinet and
designed to provide complete standalone per-
formance for RF testing.
The export classification for this equipment is
EAR99. These commodities, technology or
software are controlled for export in accord-
ance with the U.S. Export Administration Regu-
lations. Diversion contrary to U.S. law is pro-
hibited.
The Model 800A3B is a self-contained, air-
cooled, broadband, solid-state amplifier de-
signed for applications where instantaneous
bandwidth and high gain are required. The
Model 800A3B, when used with an RF sweep
generator, will provide a minimum of 800
watts of swept power.
The Model 800A3B is equipped with a digital
control panel which provides
both local and remote con-
trol of the amplifier. The
DCP uses a color LCD touch
screen and a single rotary
knob to offer status reporting
and control capability. The
display provides operational
presentation of forward
power and reflected power,
plus control status and re-
ports of internal amplifier status. Special fea-
tures include a gain control, RF output level
protection, and a transformer with selectable
taps for matching to different load impedanc-
es.
