125S1G6
 M1–M4
 125 Watts CW
 0.7GHz–6GHz
The Model 125S1G6 is a solid-state, Class A
design, self-contained, air-cooled, broadband
amplifier designed for applications where instantaneous bandwidth, high gain and linearity
are required. Housed in a stylish contemporary cabinet, the unit is designed for benchtop
use, but can be removed from the cabinet for
immediate equipment rack mounting.
The 125S1G6, when used with a sweep generator, will provide a minimum of 125 watts of
RF power. Included is a front panel gain control which permits the operator
to conveniently set the desired
output level. The 125S1G6 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 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 overtemperature 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 indications

are available remotely in 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.
The low level of spurious signals and linearity
of the Model 125S1G6 make it ideal for use
as a driver amplifier in testing wireless and
communication components and subsystems.
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 modulation envelopes are desired.
The export classification for this equipment is
3A001. These commodities, technology or
software are controlled for export in accordance with the U.S. Export Administration Regulations. Diversion contrary to U.S. law is prohibited.
