1. GENERAL INFORMATION
1.1 GENERAL DESCRIPTION
The Model 10U1000 is a self-contained, broadband solid-state amplifier designed for laboratory applications
where instantaneous bandwidth, high gain, and moderate power output are required. A GAIN control, which
is conveniently located on the unit’s front panel, can be used to decrease the amplifier’s gain by 20 decibels
(dB) or more. Solid state technology is used exclusively to offer significant advantages in reliability and
cost. A Model 10U1000, used with a frequency-swept signal source, will provide 10 watts of swept power
output from .01–1000 megahertz (MHz). Typical applications include antenna and component testing,
wattmeter calibration, and electromagnetic interference (EMI) susceptibility testing, as well as usage as a
driver for frequency multipliers and high-power amplifiers. The Model 10U1000 can be operated locally by
using the unit’s front panel controls, or remotely by using the unit’s IEEE-488, RS-232 interface, USB, or
Ethernet interface.
Special features incorporated into the Model 10U1000 include the following:
•
A Control Panel that allows both local and remote (via a computer interface) control of the amplifier
(including adjustment of the amplifier’s RF Gain during CW mode operation) and provides graphical
displays of the amplifier’s Forward and Reflected power levels.
• A General Purpose Interface Bus (GPIB)/IEEE-488.2 interface for remote control of the amplifier’s
operating functions.
• RS232 serial communications including both wire and fiber-optic ports for remote control.
•
USB Communication port for remote control.
• Ethernet Communication port for remote control.
•
Protection is provided by DC current limiting, over-temperature shut down and RF power limiting.
1.2 SPECIFICATIONS
Refer to the AR RF/Microwave Instrumentation Data Sheet at the end of this section for detailed
specifications.
1.3 POWER SUPPLIES
The Model 10U1000 contains two switching power supplies. The input voltage range to the power supply is
100–240 VAC, 50/60Hz, selected automatically. The AC input power is approximately 150 watts.
PS1 is a multiple output supply. PS1 has a +5 volt, standby supply for the A4 Control/Fault board and the A5
Interface board used for the remote interfaces. The -15V is supplied to the A1 Pre-Amp and A2 Final
Module.
PS2 su24V to the A10 Regulator Assembly for the operation of the Fan Assembly (B1). PS2 supplies
+28 to Final Module A2
Primary AC circuit protection is provided by the circuit breaker in the Power Entry Module.
