Switching Diagram

The E1470A Cascade RF Switch module consists of a series of twenty

3-to-1 multiplexers. Each 3-to-1 multiplexer can be programatically

cascaded with other 3-to-1 multiplexers to form larger multiplexers. For

example, combining two adjacent multiplexers (cascading) forms a 6-to-1

multiplexer, cascading 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 to the module are to SMB connectors on the faceplate.

Figure 1-2 shows the switching diagram of the Cascade RF Switch module

with the switches shown in the power-on/reset state.

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

be

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

terminal (the power-on/reset state). Relays are considered to be

set (or

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

See Figure 1-1.

12 Configuring the RF Switch

Chapter 1

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 20independent 3-to-1 multiplexers. By specifying a valid path

from a COM terminalto a channelin a different bank (functionally cascading

contiguous 3-to-1 multiplexers) other multiplexer sizes can be configured.

Figure 1-3 shows typical 3-to-1, 6-to-1, 9-to-1, and 12-to-1 multiplexers.

Other sizes can be configuredby specifying validROUTe:PATH statements

(see Chapter 2 for details). See Figure 1-2 for channel and COM numbering

information.

NOTE Generally, the COM terminal is on the highest-numbered bank. Exceptions

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 well as to COM 33.

For example, COM 01 can be used as the common for channels 000 - 002

and 010 - 012 creating a 6-to-1 multiplexer. 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 can be the common for channels 000 - 002, 010 - 012,

020 - 022, and 030 - 032 for a 12-to-1 multiplexer.

creating an 18-to-1 multiplexer. Multiplexers of 21-to-1, 24-to-1, and 27-to-1

can also be configured. Two 30-to-1 multiplexers can be created using

channels 00 through 132 to COM 05 and channels 200 through 332 to

COM 25. One 60-to-1 multiplexer can be created using all the channels

to COM 25.

RF Switch Configuration

This section gives guidelines to configure the RF Switch module, including:

• Warnings and Cautions

• Selecting the Logical Address

• 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 maximum RF power that can be applied

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.

14 Configuring the RF Switch

Chapter 1

Setting the Logical

Address

Thelogical addressofthe CascadeRF Switch moduleis set with theLogical

Address (LADDR) switch on the module. The logical address is factory-set

to120.Valid addresses are from 1 to 256.See Figure 1-4 for addressswitch

settings.

The logical address is the sum of the values of the switches set to the

CLOSED position. InFigure 1-4, switches 3 through 6 are CLOSED and the

associated values of these switches are 8, 16, 32, and 64. Thus, the logical

address = 8 + 16 + 32 + 64 = 128.

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

Module, the 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 Resource

Manager automatically assigns a Logical Address to the module. You can

poll theResource Manager to determine the logicaladdress assigned to the

module.

Setting the Interrupt

Request Level

Interruptsareenabledatpower-up,afteraSYSRESET,orafterresettingthe

module via the Control Register (see Appendix B). If interrupts are enabled,

the system generates an interrupt after writing to any relay control register.

Theinterruptisgeneratedapproximately13msec afterwritingtotheregister

to indicate the end of relay closure/settling time.

As shown in Figure 1-5, the Interrupt Request Level switch selects the

priority level that will be asserted. The Interrupt Request Level switch is set

in position 1 as shipped from the factory. For most applications this priority

level should not be changed. The interrupts are disabled when set to

position 'X'. To change the setting, set the switch to the level required.

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

B). Also, consult your mainframe manual to make sure backplane

jumpers/switches are configured correctly.

Configuring the RF Switch 17

Chapter 1

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

jacks and 10 connector housings. You must supply your own 50Ω

double-shielded cable (single-shielded cable can also be used). Agilent

recommends RG188DS or RS316DS double-shielded cables or

triple-shielded cable (part number 8120-0552).

Standard SMB connector jacks will fit into the Cascade RF Switch module

connector sockets and may be used if adjacent sockets on the module are

NOT used. However, the outside diameter of the standard SMB jacks

prohibits using them on the closely spaced, adjacent sockets on the module

and they will not fit in the connector housing. Special jacks with a smaller

shoulder must be used if adjacent sockets on the module are used. See

Table 1-1.

Assembling SMB

Connector Jacks

Figure 1-7 shows how to assemble the SMB connector jacks. Jacks for

double-shielded cable require a 0.151 hex crimp about 0.260 wide.

Individual jacks for single-shielded RG188 and RG316 cable are available

from E. F. Johnson Co (part number 131-4303-011/020) and require a hex

crimp size of 0.128.

Programming the RF Switch

Using This Chapter

This chapter gives guidelines to program the Cascade RF Switch module

(RF Switch) including:

• InstallingDeviceDrivers..............................19

• AddressingtheSwitch...............................20

• ProgrammingExamples..............................21

Installing Device Drivers

Before you can use the Cascade RF Switch module, you may need toinstall

device drivers. The type of driver(s) to be installed depend on whether you

use an E1406 Command Module or another type of command module. The

two types of drivers applicable to the RF Switch module are VXIplug&play

Instrument Drivers (installed on your PC) and SCPI Instrument Drivers

(downloaded into the E1406 Command Module).

NOTE It is highly recommended the SCPI Instrument driver be installed whether

the VXI instrument is programmed using its VXIplug&play driver or using

SCPI commands embedded in an I/O language. For the latest information

on drivers, see the Agilent Web Site:

To download the SCPI Instrument Driver into the E1406A Command

Module, you will need to use the VXI InstallationConsultant (VIC)contained

on the Agilent Technologies Universal Instrument Drivers CD. To download

the driver, install the CD in your CD-ROM drive and follow the installation

instructions. The setup program should run automatically. If it does not,

click

and type in the command line,

where <drive> is the letter for your CD-ROM drive.

NOTE To download a driver, the ROM version number of the E1406 Command

Module must be A.06.00 or above. To determine the version number, send

the IEEE 488.2 common command *IDN?. A typical return value follows,

where A.06.01 is the version number.

20 Programming the RF Switch

Chapter 2

Addressing the Switch

By specifying a path destination (a COM number) and a source (a channel

number), a channel is connected to a COM terminal. The format for

addressing the switch is

where < > is a 2-digit numberspecifying thebankfor theCOMterminal

and <

> is a 3-digit number specifying a channel number. (Leading

0s can be omitted.) See the

command in

Chapter 3 for valid <

> and < > numbers.

You can use

to indicate

whether a path is closed (returns a 1) or is open (returns a 0). You can

use the PATH statement to create multiple 3-to-1 multiplexers, 6-to-1

multiplexers, 9-to-1 multiplexers, 12-to-1 multiplexers, etc. Up to two

30-to-1 multiplexers or one 60-to-1 multiplexer can be configured. For

example, the following statements each connect a COM terminal to a

channel.

PATH COMM 00,001

!Connects COM 00 to Channel 001,

!COM 00 is commontochannels000,

!001, 002; forming a 3-to-1 mux.

PATH COMM 04,020

!Connects COM 04 to Channel 020,

!COM 04 is common to channels 020

!through 042; forming a 9-to-1 mux.

PATH COMM 05,002

!Connects COM 05 to Channel 002,

!COM 05 is common to channels 000

!through 052 forming an 18-to-1 mux.

Using invalid numbers for

and will generate an error.

When switching a signal path, only the relays necessary to complete the

path are switched. All other relays remain in their current state. This

prevents unexpected switching results. However, when closing one signal

path, another signal path might

open. For example:

PATH COMM 01,010

!Closes a signal path from COM 01

!to Channel 010.

PATH COMM? 01,010

!Returns "1" indicating the path is

!closed.

PATH COMM 02,002

!Closes a signal path from COM 02 to

!Channel 002 and changes the state

!of the cascade relay, opening the

!prior signal path.

PATH COMM? 01,010

!Returns "0" indicating the path is

!open.
