(dB) or more. Solid state technology is used exclusively to offer significant advantages in reliability and cost. A Model 600A400, used with a frequency-swept signal source, will provide 600 watts of swept power output from .01–400 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. -
Page 20: Installation
Select an operating location that will permit air to circulate freely around the amplifier’s cabinet. The Model 600A400 utilizes air cooling and should be located where the normal flow of air into or exiting from the unit will not be restricted, diverted, or re-circulated through the unit itself; in particular, the flow of warm air exiting the rear of the amplifier should not be impeded. - Page 21 Model 600A400 1.5.3 RF Sample Ports (Optional) The Forward and Reverse power sample port connectors are Type N female and can be located on the front or rear of the amplifier depending on ordered configuration. Cables and equipment connected to these ports should exhibit resistive 50Ω...

Page 32: Remote Control Interface
For GPIB operation, the device address is set using the front panel touch screen. Ensure that each device connected to the GPIB is set to a unique address. To send commands be sure that the 600A400’s address is set properly and that the controller has correctly identified it as a “listening” device. -
Page 33: Fiber-Optic Serial Communication
The Fiber-Optic port provides the user with the ability to optically isolate the controlling PC from the 600A400. This can be useful in an environment where RF/Microwave energy could be coupled onto a connection to one of the “wired” communications ports and fed back to the controlling PC. -
Page 34: Usb Communication
This port can be used in conjunction with either an AR model IF7000 RS-232 to Fiber-Optic Interface (1200 to 9600 baud only) or an AR model IF7001 USB to Fiber-Optic Interface (19200 baud only). Note that these devices use SMA connectors so a fiber-optic cable is needed with ST connectors on one end and SMA connectors on the other. -
Page 35: Remote Commands
An application program on the computer/controller should issue only one character string (command or query) at a time. After each functional command is issued, the 600A400’s status should be checked to ensure that the command has been properly executed. The application program should allow sufficient time for the function to be completed before checking the status. -
