and remote control of the amplifier. The DCP
uses a color LCD touch screen display to indi-
cate the operate status and fault conditions if
an over-temperature or power supply fault has
occurred. The unit can be returned 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 125S1G2z5 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 125S1G2z5, when used with a
sweep generator, will provide 125 watts of RF
power. Included is a front panel gain control
which permits the operator to conveniently set
the desired output level. The 125S1G2z5 is
protected from RF input overdrive by an RF
input leveling circuit which controls the RF input
level to the RF ampli-
fier first stage when
the RF input level is
increased above
0dBm. The RF ampli-
fier stages are pro-
tected from over-
temperature by removing the DC voltage to
them if an over-temperature condition occurs
due to cooling blockage or fan failure. The
Model 125S1G2z5 is equipped with a Digital
Control Panel (DCP) which provides both local
