  • Page 13: Creating Multiple Multiplexers

    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. By specifying a valid path from a COM terminal to a channel in a different bank (functionally cascading contiguous 3-to-1 multiplexers) other multiplexer sizes can be configured.

  • Page 14: Configuring The Rf Switch 13

    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 all channels from 000 through 052 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.

  • Page 15: Setting The Logical Address

    Setting the Logical The logical address of the Cascade RF Switch module is set with the Logical Address (LADDR) switch on the module. The logical address is factory-set Address to 120. Valid addresses are from 1 to 256. See Figure 1-4 for address switch settings.

  • Page 16: Setting The Interrupt Request Level

    Setting the Interrupt Interrupts are enabled at power-up, after a SYSRESET, or after resetting the module via the Control Register (see Appendix B). If interrupts are enabled, Request Level the system generates an interrupt after writing to any relay control register. The interrupt is generated approximately 13 msec after writing to the register to indicate the end of relay closure/settling time.

  • Page 17: Connecting User Wiring

    Connecting User User wiring connections to the module are via multiple connector blocks (part number 1250-2563). Figure 1-6 shows how to wire and assemble the Wiring connector housing. See “Cables and Connectors” for guidelines to assemble SMB jacks and connectors. See Table 1-2 in “User Wiring Log” for a log to record your wiring configuration.
  • Page 18 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).
  • Page 19 User Wiring Table Table 1-2 provides a log for you to document wiring to the Cascade RF Switch module. See Figure 1-1 for terminal identification. See Figure 1-6 for guidelines to connect user wiring. You can copy the table as desired. Table 1-2.

  • Page 28: Rf Switch Command Reference

    Chapter 3 RF Switch Command Reference This chapter describes Standard Commands for Programmable Instruments (SCPI) and summarizes IEEE 488.2 Common (*) Commands applicable to the E1470A Cascade RF Switch Module. Command Types Commands are separated into two types: IEEE 488.2 Common Commands and SCPI Commands.

  • Page 29: Linking Commands

    For example, if the command syntax shows MEASure, then MEAS and MEASURE are both acceptable forms. Other forms of MEASure, such as MEASU or MEASUR will generate an error. You may use upper or lower case letters. Therefore, MEASURE, measure, and MeAsUrE are all acceptable.

  • Page 30: Diagnostic

    DIAGnostic The DIAGnostic subsystem contains instrument-specific commands is are not recommended for general programming. For the E1470A, the DIAG subsystem allows you to open/close individual relays and query individual relays.

  • Page 43: The Base Address

    The Base Address When you are reading or writing to a module register, a hexadecimal or decimal register address is specified. This address consists of a base address plus a register offset. The base address used in register-based programming depends on whether the A16 address space is outside or inside the E1406 Command Module.

    A16 Address Space When the E1406 Command Module is not part of your VXIbus system, the Outside the Command E1470 base address is computed as: Module = C000 + (LADDR * 40 base or (decimal) = 49,152 + (LADDR * 64) base where C000 (49,152) is the starting location of the register addresses,...

  • Page 46: Manufacturer Identification Register

    CAUTION Registers have been documented as 8-bit bytes. If you access them using 16-bit transfers from a Motorola CPU, the high and low byte will be swapped. The E1406 uses Motorola CPUs. Motorola CPUs place the highest weighted byte in the lower memory location and the lower weighted byte in the higher memory address while Intel processors do just the opposite.

  • Page 47: Relay Control Registers

    Relay Control These registers control the individual E1470A relays. When a “1” is written to a bit, the relay controlled by that bit becomes SET (COMMON to NO). Registers When a “0” is written to a bit, the relay controlled by that bit becomes RESET to NC, the power-on state).
