    Chapter 1 Getting Started with the HP E1351A/53A Using This Chapter This chapter describes the HP E1351A 16-Channel FET and the HP E1353A 16-Channel Thermocouple FET Multiplexer Modules, and shows how to program the modules using SCPI (Standard Commands for Programmable Instruments) commands.

  • Page 12: Multimeter Connection Points

    Analog Bus The analog bus connector provides a direct connection between multiple multiplexer modules and also between a multiplexer module and HP Connector E1326/E1411 Multimeters. A ribbon cable is used to daisy-chain multiple multiplexer modules together, and to connect a multimeter to the multiplexer modules for a scanning voltmeter.

  • Page 18: Multiplexer Card Numbers

    Multiplexer Card Numbers HP plug-in modules installed in an HP VXIbus mainframe are treated as independent instruments each having a unique secondary HP-IB address. An instrument may be composed of a single plug-in module or multiple plug-in modules. The card number identifies the module within a switchbox or scanning voltmeter configuration.

  • Page 19: Setting The Address Switch

    Valid address values are Switch from 1 to 255. Refer to the HP 75000 Series B System Installation and Getting Started Guide or the appropriate HP Command Module Manual for addressing information. Otherwise, refer to Figure 2-4 to reset the factory setting.

    Refer to Figure 2-5 to change the interrupt lines. Valid line numbers are from 1 to 7. Set the interrupt line number to the mainframe interrupt handler number. Figure 2-5. Setting the Interrupt Line Number Configuring the HP E1351A/53A FET Multiplexer Modules Chapter 2...

  • Page 21: Setting The Card Id Switch

    Setting the Card ID Switch The multiplexer module can be an HP E1351A, HP E1352A or HP E1353A depending on which terminal module is installed. With a normal connection, the terminal module will automatically configure the module for the appropriate model. To identify a module without a terminal module, set the Card ID switch as shown in Figure 2-6.

    Register addresses for register-based devices are located in the upper 25% of VXIbus A16 address space. Every VXIbus device (up to 256 devices) is allocated a 32 word (64 byte) block of addresses. The HP E1351A/E1353A multiplexers use eight two-byte registers of the 64 addresses (32 word registers) allocated.
