is detected. The touch screen display on the
front panel indicates the operational status and
any pending fault conditions when an over-
temperature, over-current or power supply
fault has occurred. The unit can be returned to
normal operation when the condition has been
cleared. The unit also includes digital control
for both local and remote control of the ampli-
fier. The RISC microprocessor controller board
provides IEEE-488 (GPIB), USB, Ethernet and
asynchronous full duplex RS-232 communica-
tion control of all amplifier functions.
Two 350AH1A amplifiers may be used togeth-
er in a “bridged” output configuration by sup-
plying the same signal to both amplifiers and
using the internal signal inversion feature of
one amplifier. The amplifier output grounds
are connected and the load is placed across
the two amplifier outputs.

The Model 350AH1A amplifier is a portable,
self-contained, air-cooled, broadband, solid
state amplifier unit designed for laboratory
applications where instantaneous bandwidth,
high gain and moderate power output are
required. When used with an RF sweep gener-
ator, the 350AH1A will provide up to 350
watts of output power.
Housed in a stylish contemporary enclosure,
the unit provides instantaneous power for typi-
cal applications such as magnetic susceptibility
testing, 4–10 kHz require-
ment of CS114 of MIL-Std-
461F, antenna and compo-
nent testing, watt-meter
calibration and as a driver
for higher power amplifiers.
The 350AH1A is powered
by a high efficiency switching supply, with au-
toranging AC input circuitry which will auto-
matically accept voltages from 90 to 260 VAC
in the 47 to 63 Hz frequency range. The RF
amplifier stages are protected from over-
temperature and over-current conditions by
removing the DC voltage to them when a fault
