Instrument Definition

HP plug-in modules installed in an HP mainframe or used with an HP command module are treated as independent instruments each having a unique secondary HP-IB address. Each instrument is also assigned a dedicated error queue, input and output buffers, status registers and, if applicable, dedicated mainframe/command module memory space for readings or data. An instrument may be composed of a single plug-in module (such as a counter) or multiple plug-in modules (for a switchbox or scanning voltmeter instrument).

Programming the Microwave Switch

To program the modules using SCPI commands, you must select the controller Module language, interface address, and appropriate commands. See the HP 75000 Series B Installation and Getting Started Guide or the appropriate HP Command Module Manual for interface addressing and controller language information of Microwave Switch modules in a switchbox or scanning voltmeter configuration.

Note This discussion applies to SCPI programming. See Appendix B (Microwave Switch Registers) for details on Microwave Switch modules registers.

Selecting Channels: To address specific channels within a Microwave

Switch module in a switchbox, you must:

∙send the appropriate SCPI command string to the switchbox (e.g., CLOSe, OPEN, etc.). For the Microwave Switch modules, use the CLOSe command to connect the 2-port to the C-port. Use the OPEN command to connect the 1-port to the C-port.

	∙ specify the card number (01-99)	= channel_list
	∙ specify the channel number (00-04)	= channel_list
	∙ specify the channel number (00-04)	}

Card Numbers The card number identifies the module within a switchbox. The Microwave Switch card number depends on the switchbox configuration (single-module or multiple-module) set for the switches.

∙Single-module.For a single-module switchbox, the card number is always 01.

∙Multiple-module.For a multiple-module switchbox, the switch module with the lowest logical address is always card number 01. The card number with the next successive logical address is 02, and so on. Figure 1-2 illustrates the card numbers and logical addresses of a typical multiple-module switchbox.
