    All components should be immediately inspected for damage upon receipt of the unit. Once the VM2710A is assessed to be in good condition, it may be installed into an appropriate C-size or D-size VXIbus chassis in any slot other than slot zero. The chassis should be checked to ensure that it is capable of providing adequate power and cooling for the VM2710A.

  • Page 22: Setting The Logical Address

    OGICAL DDRESS The logical address of the VM2710A is set by a single 8-position DIP switch located near the VMIP module’s backplane connectors (this is the only switch on the module). The switch is labeled with positions 1 through 8 and with an ON position. A switch pushed toward the ON legend will signify a logic 1;...

  • Page 23: Front Panel Interface Wiring

    VM2710A-1 will have J201 that contains all signals for this instrument. The VM2710A-2 will have J201 and J202, while the VM2710A-3 will have J200, J201, and J202. The wiring for each of these connectors is identical and since each group is treated as a separate instrument, the module will have three A channels and three B channels.

  • Page 24: Section 3

    ROGRAMMING NTRODUCTION The VM2710A is a VXIbus message-based device whose command set is compliant with the Standard Command for Programmable Instruments (SCPI) programming language. All module commands are sent over the VXIbus backplane to the module. Commands may be in upper, lower or mixed case.

  • Page 34: Calibration

    The following is a summary of the CALibration commands that may be useful in calibrating the VM2710A. These commands are described in more detail in the Command Dictionary section of this manual. Some of these commands, if used improperly, can destroy the calibration of the VM2710A.
  • Page 35 CALibration:CONVert:OFFSet? Reports the offset of the current function and range setting of the VM2710A. See the Offset column in Table 3-1 Function and Range. This query returns the constants for the currently set range and function. CALibration:CONVert:OFFSet:CURRent:AC? Reports the offset for a specified range in the ac Current function.
  • Page 36 Sets the range for the zero measurement in the dc voltage function and takes a zero reading. If no value is entered, then the VM2710A will take a zero measurement for each of the voltage ranges, thus taking more time.

    OFF | REG Description Data (measurements) are retrieved from the VM2710A using two different methods. For most systems, the easiest method to use is word serial data transfers. This is the same technique used to program the module and query the module's settings. When fast response time is important, measurements can be retrieved using register access.

  • Page 152: Trigger:buffered

    After the reading is complete, the stored trigger satisfies the EXT event if the multimeter is programmed as such. However, a second trigger occurring during a reading will still generate a "trigger too fast" error. Examples Command / Query Response (Description) TRIG:BUFF ON TRIG:BUFF? Related Commands VM2710A Command Dictionary...

  • Page 153: Trigger:count

    Once INITiate is used to start operation, ABORt or *RST command must be used to remove the voltmeter form the countinuous opeation. The CONFigure and MEASure commands set the trigger count to 1.

  • Page 156: Trigger[:Immediate]

    TRIGger:IMMediate is executed. The levels of trigger commands containing the IMMediate parameter are different. The TRIGger:SOURce:IMMediate bypasses the trigger system so that the VM2710A is triggered immediately only if it is in the wait-for-trigger state. The TRIGger:IMMediate command causes a single trigger cycle to happen after the trigger system has been disabled.

    This command determines whether the rising or falling edge of the front panel signal will trigger the multimeter. Examples Command / Query Response (Description) TRIG:SLOP POS (Sets the multimeter to trigger on the rising edge of the front panel signal.) TRIG:SLOP? Related Commands VM2710A Command Dictionary...

    IMMediate The trigger system is always true. A trigger will happen immediately if the VM2710A is in wait-for-trigger state. This is the default setting. TTLTrg <n> The VXIbus TTL trigger lines on the backplane. Note that the CONFigure and MEASure command subsystems automatically reset the trigger source to TRIGger:SOURce:IMMediate.
