conditions if an over-temperature or power
supply fault has occurred. The unit can be re-
turned to operate when the condition has been
cleared.
All amplifier control functions and status indi-
cations are available remotely through the
included Remotes Package. The Remotes Pack-
age includes GPIB/IEEE-488 format, RS-232
hardwire and fiber optic, USB, and Ethernet.
The bus interface connector is located on the
back panel and positive control of local or
remote operation is assured by a Local/Remote
switch on the front panel of the amplifier. Also
included with the Remotes Package is a safety
interlock circuit for use with external safety
switch interlocks. This circuit prevents the am-
plifier from going into operate mode unless the
external connection is made. A jumper plug is
provided for cases where this functionality is
not needed.
The export classification for this equipment is
EAR99.
The Model 175A400 is a solid-state, self-
contained, air-cooled, broadband amplifier
designed for applications where instantaneous
bandwidth, high gain and linearity are re-
quired. Available in a stylish, contemporary
cabinet for benchtop use or with cabinet re-
moved for rack mounting.
The Model 175A400, when used with a sweep
generator, will provide a minimum of 175
watts of RF power. Included is a front panel
gain control which permits the operator to
conveniently set the desired output level. The
175A400 is protected from RF input overdrive
by an RF input leveling circuit which controls
the RF input level to the RF amplifier first stage
when the RF input level is increased above
0dBm. The RF amplifier stages are protected
from over-temperature by removing the DC
voltage to them if an over-temperature condi-
tion occurs due to cooling blockage or fan
failure. The Model 175A400 is equipped with
a Digital Control Panel (DCP) which provides
both local and remote control of the amplifier.
The DCP uses a color LCD touch screen dis-
play to indicate the operate status and fault
