Configuring the RF Switch

This c hapt er gives guidelines t o use the Casc ade RF Switch module (RF S witch) including:

• SwitchingDiagram...................................9

• CreatingMultipleMultiplexers..........................12

• RFSwitchConfiguration..............................14

The E 1470A Cascade RF Switch module c onsists of a series of twenty 3-to-1 m ultiple xe rs. Each 3-to-1 multiplexer can be programatically cascaded with other 3-to-1 multiplexers to form larger multiplexers. For example, c ombining two adjacent multiplexers (cascading) forms a 6-to-1 multiplexer, casc ading three forms a 9-to-1 multiplexer, or cascading four forms a 12-to-1 multiplexer, etc. Cascading all twenty 3-to-1 multiplexers forms one 60-to-1 multiplexer.

Multiple combinations are simultaneously allowed on the module. User connections t o the module are to SMB connectors on the faceplate. Figure 1-2 shows the switching d iagram of the Cascade RF Switch module with the switches s hown in the power-on/reset state.

Since the relays on the switch are Form C, the relays are considered to

reset (or opened) when the COM MON terminal is connected to the NC

be terminal (the power-on/reset state). Relays are c ons idered to be

closed) when the COMMON terminal is connected to the NO terminal.

Creating Multiple Multiplexers

You can configure the Cascade RF Switch module to create multiple multiplexers of varying sizes. In its power-on/reset state, the switch is configured as 20 independent 3-to-1 multiplexers. Byspecifying a v alid path from a COM terminal to a channel in adifferent bank (functionally c ascading contiguous 3-to-1 multiplexe rs) other multiplexer sizes can be conf igured.

Figure 1 -3 shows typical 3-to-1, 6-to-1, 9-to-1, and 12-t o-1 multiplexers. Other sizes can be configured by spec if y ing validROUTe:PATH statements (see Chapter 2 for details). See Figure 1-2 for channel and COM numbering information.

are that channels 100 through 132 can go to COM 05 as well as to COM 13 and channels 300 through 332 can go to COM 25 as wel l as to COM 33.

For example, COM 01 can be used as the common for channels 000 - 002 and 010 - 012 creat ing a 6-to-1 mult iple xer. COM 11 can be the common forchannels 100 - 102 and 110 - 112 for another 6-to-1 multiplexer. COM 02 can be common for channels 000 - 002, 010 - 012, and 020 - 022 for a 9-to-1 multiplexer. COM 03 c an be the common for channels 000 - 002, 010 - 012, 020 - 022, and 030 - 032 for a 12-to-1 m ultiplexer.

Chapter 1

COM 04 can be used for a 15-to-1 multiplexer for all channels between 000 and 042. COM 05 can be the common for al l channelsfrom 000 t hrough 052 creating an 18-to-1 multiplexer. M ult ipl ex ers of 21-to-1,24-to-1,and 27-to-1 can a lso be c onf igured. Two 30-to-1 multiplexers can be creat ed using channels 00 through 132 to COM 05 and channels 200 through 332 to COM 25. One 60-to-1 multiplexer c an be created us ing all the channels to CO M 25.

RF Switch Configuration

This s ec tion gives guidelines to configure the RF Switch module, including:

• Warnings and Cautions

• Select ing the Logical Ad dress

• Setting the Interrupt Request Level

• Connecting User Wiring

Warnings and

Cautions

WARNING SHOCK HAZARD. Only service-trained personnel who are

aware of the hazards involved should install, remove, or configure the module. Before you remove any installed module, disconnect AC power from the mainframe and from other modules that may be connected to the module.

WARNING CHANNEL WIRING INSULATION. All channels that have a

common connection must be insulated so that the user is protected from electrical shock in the event that two or more channels are connected together. This means wiring for all channels must be insulated as though each channel carries the voltage of the highest voltage channel.

CAUTION MAXIMUM POWER. The maxim um RF power t hat can be appli ed

to the module is 10 Watts RF. Do not apply line AC power to any terminal on this module.

CAUTION STATIC ELECTRICITY. Static electricity is a major cause of component

failure. To prevent damage to the electrical components in the module, observe anti-static techniques whenever removing a module from the mainframe or working on a module.

Chapter 1

Configuring the R F Switch 13

Setting the Logical

Address

NOTE When using the Cascade RF Switch module with an E1406 Command

Thelogicaladdress of the Cascade RF Switch module is set with the Logical Address (LA DDR) switch on the module. The logical address is factory-set to120.Valid address es are from 1 to 256. See Figure 1-4 for address switch settings.

The logical address is the sum of the values of the switches set to the CLOSED position. In F igure 1-4,switches 3 through 6 are CLOSED andthe associated values of these switches are 8, 16, 32, and 64. Thus, the logical address = 8 + 16 + 32 + 64 = 128.

Module, t he address must be a multiple of 8 (for example, 8, 16, 24,... 112, 120, 128, . .. 240, 248). The module cannot be configured as part of a multiple-module switchbox instrument.

If the Logical Address Switches are set for 255, the System Res ourc e Manager automatically ass igns a Logical Address to the module. You c an poll the Resource Manager to determine the logical address assigned tothe module.

Logical Address

Chapter 1

Setting the Interrupt

Request Level

NOTE Interrupts can also be disabled using the Control Register (see Appendix

Interruptsare enableda t power-up,aftera SYSRESET,ora fterresettingthe module via the Control Register (see Appendix B). If interruptsare enabled, the system generates an interrupt after writing to any relay cont rol register. Theinterrupt is generated approximately 13msecafter writing to theregister to indicate the end of relay closure/settling time.

As s hown in Figure 1-5, the Interrupt Request Level switch selects the priority level that will be asserted. The Interrupt Re quest Level sw itch is set in posit ion 1 as shipped from the factory. For most applications this priority level should not be changed. The interrupts are disabl ed when set to position 'X'. To c hange the setting, set the switch to the level required.

B). Also, consult your mainframe manual to make s ure backplane jumpers/switches are configured correctly.

Connecting User

Wiring

User wi ring connections to the module are via multiple connector bloc k s (part num ber 1250-2563). Figure 1-6 shows how to wire and assemble th e connector housing.

Cables and Connectors The Cas c ade RF Switch module is shipped with a kit of 85 SMB connector

jacks and 10 connector housings. You mus t supply your own 50Ω double-shielded cable (single-shielded cable can also be used). Agilent recommends RG188DS or RS 316DS double-shielde d cables or triple-shielded cable (part number 8120-0552).

Standard S MB connector jacks will fit into the Cascade RF Switch module connector sockets and may be used if adjacent sockets on the module are NOT us ed. However, the outside diameter of the standard SMB jacks prohibits using them on thec losely spaced, adjacent sockets on t he module and they will not fit in th e connector housing. Special jacks with a smaller shoulder must be used if adjacent sockets on the module are used. See Table 1-1.
