The availability of the remote resources can also be tested in MAX using a graphical user interface (Figure 12.35). In order to do this the user needs to select the desired instrument (e.g., GPIB::4::INSTR) and then click on the "Open VISA Test Panel" button. In the window that opens, the user can enter commands for the instruments (Write function) and read their answer (Read function). In order to show the manner in which Remote VISA calls can be used to develop remote experiments we have implemented a proof-of-concept application controlling: An experiment board UUT (unit-under-test) A stimuli generator (programmable power supply-Hameg HM8142 with the GPIB address 4) A digital multimeter (HP34401A DMM with the GPIB address 22) A relay board connected on the parallel port (for its advantage of being "latched") of the instrumentation work-bench server; the relays are used for (reconfiguration) switching but also for test point multiplexing or load- adjustment and SO on; for instance, the Centronics port of the work-bench server, having the address 378 h = 888 (10) can simply be controlled in LabVIEW by selection Tele-Measurement Services for m-Learning visa://82.78.149.213/GPIB0:4:INSTR (Session 0x036D3520) iSetAttribute viWrite viRead viClear Show All VISA Operations Attribute Name Current Value VI_ATTR_TMO_VALUE Value Return Status View All Settable Attributes Modify the value of the specified attribute.
