Figure 4-2. Trigger Sources for ScanningChapter 4Understanding the Relay Multiplexer Modules 43<strong>Artisan</strong> Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
Example: Scanning WithExternal DevicesThis example uses the mainframe "Trig Out" port to synchronize themultiplexers to an HP 3457A Digital Multimeter. See the following figurefor typical connections. For this example, use the trigger output pulse of themainframe "Trig Out" port to trigger the multimeter via its External Triggerport. The sequence of operation is:1. INIT (line 70) closes channel number 100.2. The channel closure causes a trigger output from the "Trig Out" port.3. The trigger causes the multimeter to make a measurement.4. Measurement result is sent to the computer (lines 80 to 100).5. TRIGGER (line 110) advances the channel list to the next channel.6. Steps 2-5 are repeated for channels 101 through 115.10 OUTPUT 722;"TRIG EXT;DCV" !Sets multimeter to externaltrigger and to measure dc volts.20 OUTPUT 70914;"OUTP ON" !Enables "Trig Out" port.30 OUTPUT 70914;"TRIG:SOUR BUS" !Sets switchbox to receive Bustriggers.40 OUTPUT 70914;"SCAN:MODE VOLT" !Sets switchbox to measurevoltage.50 OUTPUT 70914;"SCAN:PORT ABUS" !Closes the AT and AT2 TreeSwitches.60 OUTPUT 70914;"SCAN (@100:115)" !Selects the channel list forscanning.70 OUTPUT 70914;"INIT" !Starts scanning cycle.80 FOR I=1 TO 16 !Start count loop.90 ENTER 722;A !Enter reading into variable A.100 PRINT A !Print reading in variable A.110 TRIGGER 70914 !Trigger the switchbox toadvance the channel list.120 NEXT I !Increment count.130 END44 Understanding the Relay Multiplexer Modules Chapter 4<strong>Artisan</strong> Technology Group - Quality Instrumentation ...
