1. GENERAL INFORMATION
1.1 GENERAL DESCRIPTION
The Model 1000S1G6C is a self-contained, broadband microwave 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
10 decibels (dB) or more. Solid-state technology is used exclusively to offer significant advantages in reliability
and cost. A Model 1000S1G6C, used with a frequency-swept signal source, will provide 1000 watts of swept
power output from 1–5.0 gigahertz (GHz) and 700 watts from 5.0–6.0 GHz. 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
1000S1G6C can be operated locally by using the unit’s front panel controls, or remotely by using the unit’s
IEEE-488, RS-232, USB, or Ethernet interfaces.
Special features incorporated into the Model 1000S1G6C include the following:
• Digital Control Panel (DCP) 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.
• RF output level protection.
•
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 Data Sheet at the end of this section for detailed specifications. All voltage measurements
referenced in this manual are Direct Current (DC) unless stated otherwise.
1.3 POWER SUPPLIES
The Model 1000S1G6C contains six switching power supplies. The input voltage range to the power supplies
is 200–240 VAC, 47/63 Hz, for the low voltage option; for the high voltage option, 380-415 VAC, 47/63 Hz
selected automatically.
PS1 is a multiple output supply. +5V and -15V is fed to the A44 and A45 Regulator Assemblies. The Regulator
Assemblies supplies -5V, -12V and +15V to the A1 Preamplifier. The Regulator assemblies also supply -8V to
(Terminal Blocks) TB1, TB3, TB4 and TB6 . -5V is also supplied to the A2 Quad Amplifier.
PS2 is a single output supply that supplies -15V to the A45 Regulator Board.
