LAN SAFETY AND MANUAL CONVENTIONS SECTION 1 This manual contains conventions regarding safety and equipment usage as described below. Product Reference Throughout this manual, the term Series 8000 refers to all models of within the series, unless otherwise specified. Personal Safety Alert! WARNING WARNING: Indicates a hazardous situation which, if not avoided, could result in death or serious injury. Equipment Safety Alert CAUTION CAUTION: Indicates a situation which can damage or adversely affect the product or associated equipment. Notes Notes are denoted and used as follows: NOTE: Highlights or amplifies an essential operating or maintenance procedure, practice, condition or statement. Electrical Safety Precautions Any servicing instructions are for use by service-trained personnel only. To avoid personal injury, do not perform any service unless you are qualified to do so. For continued protections against fire hazard, replace the AC line fuse only with a fuse of the same current rating and type. Do not use repaired fuses or short circuited fuse holders.

OVERVIEW This manual describes a version of the Series 8000 products. They are full-rack wide units with terminated RF Switches that are controlled by an Ethernet or GPIB Interface. The Series 8000 line of switch products are based on rugged electromechanical switches and microwave relays rated for use from DC to 40 GHz, with low insertion loss and high isolation. Route signals under remote control to simplify and improve automated test systems. Easily removable switches allow reduced mean time to repair. The Series 8000 is a self-contained design, with built-in power supplies, microprocessor-based controller board and up to 256 relay coils, making it easy to implement a microwave switch system. It is designed to host many combinations of microwave relay switches, terminated or non-terminated: SPDT, SP4T, SP6T, SP8T, or Transfer switches. With a standard SCPI command set, the control interface provides the Series 8000 with ease of operation and configurability. FUNCTIONAL DESCRIPTION The design is housed in a 3 RU (5.25 inch) high, full rack size unit. The unit fits in a standard 19 inch rack cabinet and is provided with mounting flanges to enable it to be mounted in the rack. The unit is self contained, that is, it contains its own power supplies, communications interface, RF relay driver circuits and the RF relays mounted on the front. The RF Switches can be removed from the front of the unit. The Ethernet interface is an IEEE-488.2 device and uses standard Control commands to control its digital interface. (See Section 2 for the Control Command Set for this instrument.) A single power supply provides +5 VDC and +12 VDC to the unit. The power supply input is 90-250 VAC, 47-63 Hz. (See Section 3 for full specifications) The RF switches are 50 Ohm impedance, with a frequency range capability of DC to 40 GHz. (See Section 4 for full specifications) WARRANTY Product is warranted to conform to all applicable specifications for a period of one (1) year from acceptance, or the relay cycle life, whichever comes first.

If the switches are physically moved to a different location in the front panel, the command parameters DO NOT change. If such a physical change is made, the user assumes the responsibility of properly identifying the switch locations. CAUTION Please consult Giga-tronics factory before making any changes in your equipment! Operation Manual, Part Number 07508000-006, Rev. A, June 26, 2013 Page 10
SWITCH CLOSURE, COUNTER, QUERY COMMANDS The SCPI commands required to set switch positions, query the switch count, and to save counters are listed below with an example switch configuration. These end user commands are always accessible. ROUTe:SWITch Sw, P Sets a switch to a desired position. Sw is the switch identification number, 1-6. P is the desired position as a decimal value. Sw Positions 1 0, 1, 2, 3, 4, 5, 6 6 0, 1, 2, 3, 4, 5, 6 NOTE: 0 = Open, or No Connection ROUTe:SWITch? Sw Returns switch position, current switch count, and switch identifier string. Sw is a number to identify the switch. The response is: Sw, position, count, ID. An example is: ROUTe:SWITch? 2 2, 5, 1002123, S/N 12345678 ROUTe:SWITch:SAVe ROUTe:SWITch:SAVe? Saves all switch counter values to flash memory. The command only saves the current counter values. Queries the number of flash saves done via the ROUTe:SWITch:SAVe command, power fail and auto save intervals. Operation Manual, Part Number 07508000-006, Rev. A, June 26, 2013 Page 11
