    Model 60S1G6 REMOTE COMMUNICATIONS This section describes remote operation of this product using the installed communications ports connected to a remote device such as a personal computer. All ports are active at all times, however only one port may be used at a time. Communicating through two or more ports at one time will cause data collisions and lost commands or queries.

  • Page 24: Rs-232 Communications

    Model 60S1G6 2.4.2 RS-232 Communications The RS-232 port is a serial communications bus. All commands and queries through this port must be terminated with a <LF>. When a valid query is received, it is processed and the result is immediately transmitted back over the RS-232 interface.

  • Page 25: Usb Communications

    The connector type for this port is ST. This port can be used with either an AR IF7000 RS-232 to Fiber-Optic Interface or an AR IF7001 USB to Fiber-Optic Interface. 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 31: Theory Of Operation

    3. THEORY OF OPERATION INTRODUCTION The Model 60S1G6 RF amplifier consists of a 0.7–6 GHz RF amplifier assembly. The RF amplifier assembly consists of a Pre-Amplifier (Pre-Amp), one (1) Quadrature-Coupled Amplifier (Quad Amp) used as a driver and four (4) Quad Amps used as final amplifier stages.

  • Page 35: Maintenance

    4. MAINTENANCE GENERAL MAINTENANCE INFORMATION The Model 60S1G6 requires very little maintenance since it is a relatively simple instrument. It is built with etched circuit wiring and solid state devices that will ensure long, trouble free life. However, should trouble occur special care must be taken in servicing to avoid damage to the devices or the etched circuit board.

    Fluorescent Display (VFD) when POWER Switch is Depressed (Schematic Diagram No. 10032325) 1. If the Model 60S1G6 is operating in an otherwise normal fashion, the front panel VFD or the wiring to it could be defective. 2. Check the LOCAL/REMOTE switch on the unit’s front panel; it must be set to the LOCAL position in order to operate the front panel POWER switch.
