Introduction to Programming 3
Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 69
Example Program
This program demonstrates the basic command structure used to program
the oscilloscope.
' Initialize the instrument interface to a known state.
myScope.IO.Clear
myScope.IO.Timeout = 15000 ' Set interface timeout to 15 seconds.
' Initialize the instrument to a preset state.
myScope.WriteString "*RST"
' Set the time base mode to normal with the horizontal time at
' 50 ms/div with 0 s of delay referenced at the center of the
' graticule.
myScope.WriteString ":TIMebase:RANGe 5E-4" ' Time base to 500 us/div.
myScope.WriteString ":TIMebase:DELay 0" ' Delay to zero.
myScope.WriteString ":TIMebase:REFerence CENTer" ' Display ref. at
' center.
' Set the vertical range to 1.6 volts full scale with center screen
' at -0.4 volts with 10:1 probe attenuation and DC coupling.
myScope.WriteString ":CHANnel1:PROBe 1.0" ' Probe attenuation
' to 1:1.
myScope.WriteString ":CHANnel1:RANGe 1.6" ' Vertical range
' 1.6 V full scale.
myScope.WriteString ":CHANnel1:OFFSet -0.4" ' Offset to -0.4.
myScope.WriteString ":CHANnel1:INPut DC" ' Coupling to DC.
' Configure the instrument to trigger at -0.4 volts with normal
' triggering.
myScope.WriteString ":TRIGger:SWEep NORMal" ' Normal triggering.
myScope.WriteString ":TRIGger:LEVel CHAN1,-0.4" ' Trigger level to -0.
4.
myScope.WriteString ":TRIGger:MODE EDGE" ' Edge triggering
myScope.WriteString ":TRIGger:EDGE:SLOPe POSitive" ' Trigger on pos. slo
pe.
' Configure the instrument for normal acquisition.
myScope.WriteString ":ACQuire:MODE RTIMe" ' Normal acquisition.
myScope.WriteString ":SYSTem:HEADer OFF" ' Turn system headers off.
myScope.WriteString ":DISPlay:GRATicule FRAMe" ' Grid off.
