occurred. The unit can be returned to oper-
ate when the condition has been cleared.  
All amplifier control functions and status 
indications are available remotely in GPIB/

IEEE-488 format, RS-232 hardwire and fi-
ber optic, USB, and Ethernet.  The bus inter-
face connector is located on the back panel 
and positive control of local or remote op-
eration is assured by a Local/Remote switch 
on the front panel of the amplifier. 
The low level of spurious signals and linear-

ity of the Model 60S1G6 make it ideal for 
use as a driver amplifier in testing wireless 
and communication components and sub-
systems.  It can be used as a test instrument 

covering multiple frequency bands and is 
suitable for a variety of communication 
technologies such as CDMA, W-CDMA, 
TDMA, GSM etc. It is also suitable for EMC 
Test applications where undistorted modu-
lation envelopes are desired.  
The export classification for this equipment 

is 3A001.  These commodities, technology 
or software are controlled for export in ac-
cordance with the U.S. Export Administra-
tion Regulations. Diversion contrary to U.S. 
law is prohibited. 

The Model 60S1G6 is a solid-state, Class A 
design, self-contained, air-cooled, broad-
band amplifier designed for applications 
where instantaneous bandwidth, high gain 

and linearity are required.  Housed in a 
stylish contemporary cabinet, the unit is de-
signed for benchtop use, but can be re-
moved from the cabinet for immediate 
equipment rack mounting. 
The 60S1G6, when used with a sweep gen-
erator, will provide a minimum of 60 watts 

of  RF  power.  Included  is  a 
front panel gain control 
which permits the operator to 
conveniently set the desired 

output level.  The 60S1G6 is 
protected from RF input over-

drive by an RF input leveling circuit which 
controls the RF input level to the RF amplifi-
er first stage when the RF input level is in-

creased above 0 dBm. The RF amplifier 
stages are protected from over-temperature 
by removing the DC voltage to them if an 
over-temperature condition occurs due to 
cooling blockage or fan failure. There is a 

digital display on the front panel to indicate 
the operate status and fault conditions if an 
over-temperature or power supply fault has
