' CHANNEL_PROBE - Sets the probe attenuation factor for the selected
' channel. The probe attenuation factor may be set from 0.1 to 1000.
' Set Probe to 10:1.
err = viVPrintf(vi, ":CHAN1:PROBE 10" + vbLf, 0)
' CHANNEL_RANGE - Sets the full scale vertical range in volts.
' range value is 8 times the volts per division.
' Set the vertical range to 8 volts.
err = viVPrintf(vi, ":CHANNEL1:RANGE 8" + vbLf, 0)
' TIME_RANGE - Sets the full scale horizontal time in seconds.
' range value is 10 times the time per division.
' Set the time range to 0.002 seconds.
err = viVPrintf(vi, ":TIM:RANG 2e-3" + vbLf, 0)
' TIME_REFERENCE - Possible values are LEFT and CENTER.
' - LEFT sets the display reference on time division from the left.
' - CENTER sets the display reference to the center of the screen.
' Set reference to center.
err = viVPrintf(vi, ":TIMEBASE:REFERENCE CENTER" + vbLf, 0)
' TRIGGER_TV_SOURCE - Selects the channel that actually produces the
' TV trigger. Any channel can be selected.
err = viVPrintf(vi, ":TRIGGER:TV:SOURCE CHANNEL1" + vbLf, 0)
' TRIGGER_MODE - Set the trigger mode to EDGE, GLITch, PATTern, CAN,
' DURation, IIC, LIN, SEQuence, SPI, TV, or USB.
' Set the trigger mode to EDGE.
err = viVPrintf(vi, ":TRIGGER:MODE EDGE" + vbLf, 0)
' TRIGGER_EDGE_SLOPE - Sets the slope of the edge for the trigger.
' Set the slope to positive.
err = viVPrintf(vi, ":TRIGGER:EDGE:SLOPE POSITIVE" + vbLf, 0)
' The following commands are not executed and are shown for reference
' purposes only. To execute these commands, uncomment them.
' RUN_STOP - (not executed in this example)
' - RUN starts the acquisition of data for the active waveform
' display.
' - STOP stops the data acquisition and turns off AUTOSTORE.
' Start data acquisition.
' err = viVPrintf(vi, ":RUN" + vbLf, 0)
' Stop the data acquisition.
' err = viVPrintf(vi, ":STOP" + vbLf, 0)
' VIEW_BLANK - (not executed in this example)
' - VIEW turns on (starts displaying) a channel or pixel memory.
