  • Page 14: Warnings And Cautions

    Warnings and Cautions WARNING SHOCK HAZARD. Only service-trained personnel who are aware of the hazards involved should install, remove, or configure the switch module. Before you remove any installed module, disconnect AC power from the mainframe and from other modules that may be connected to the modules. Do not defeat the Agilent E6171B Measurement Control Module Interlock feature with jumpers.

  • Page 15: Setting The Address Switch

    Setting the Address Switch The logical address switch is factory set at 3. You may need to change the setting the during module installation. Valid addresses are from 1 to 254. Figure 1-1 shows the module and the location of the address switches. Installing in a VXI Mainframe The Agilent E6171B Measurement Control Module can be installed in any available mainframe slot except slot 0.

  • Page 20 Figure 2-3. Bus Structure of the Trigger Multiplexer The trigger multiplexer contains two trigger buses, nominally known as TRIG1 and TRIG2, used to route signals. Any of the eight, bi-directional TTL-level triggers at the VXIbus backplane can connect to either of the trigger multiplexer's buses and can be used as trigger sources or trigger destinations.

    second source is a software programmable trigger, whose routing is controlled by bits 0 and 3 of the same register. And the third trigger source is the output from the analog comparator, denoted “trigger input,” whose routing is controlled by bits 2 and 5 of the same register. If desired, bit 13 of the register lets you invert the comparator's output sensing.

You cannot close relays on the module during an interlock event. A programmable override allows self-tests or diagnostics if the physical interlock is not present.
  • Page 23 Both modes of operation are supported in the range from 20 µs. to 655.37 ms., programmable in steps of 10 µs within 16 bits of resolution. Either of two sources can start the general-purpose timer counting: loading the General-Purpose Timer Register, or the falling edge of a waveform from the trigger multiplexer applied to its trigger input.

  • Page 24: Digital Trigger

    The proper order for setting up the timer is to first set the mode and source, then load the timing delay. Digital Trigger The digital trigger serves as an isolator to convert the earth-referenced trigger to a DUT referenced trigger. Below is a diagram of how the “floating”...

  • Page 25: Programmable Attenuator

    Programmable The Measurement Control Module has a programmable attenuator between the DUT input and the digitizer. Attenuator Figure 2-5 is a graph of the attenuator transfer function. The programmable “knee” can be set from ±1 volts to ±10 volts; ±2.5 volts is the default. Voltages near the knee voltage are not known with full accuracy and should not be measured.

  • Page 27: Power-On State

    Note Run the Agilent TestExec SL software immediately after power-on to reset the Agilent E6171B (and all other instruments in the Agilent TS-5400 system). This helps the module thermally stabilize quickly. If left in its power-on state for extended time periods, the module may take several minutes to stabilize after the software resets it.

  • Page 35: Replacement Strategy

    Replacement Strategy The replacement strategy depends on the application. If some relays are used more often, or at a higher load, than the others, the relays can be individually replaced as needed. If all the relays see similar loads and switching frequencies, the entire circuit board can be replaced when the end of relay life approaches.

  • Page 36: Appendix B Register Definitions

    Appendix B Register Definitions Addressing the Registers To access a specific register for either read or write operations, you must use its register address. Register addresses for VXIbus plug-in modules reside in an address space called "A16" whose size is FFFF .
