Vertical is set to 16 V full-scale (2 V/div) with center of screen at 1 V and probe
attenuation set to 10. This example sets the time base at 1 ms full-scale (100
ms/div) with a delay of 100 µs.
Example Oscilloscope Setup Code
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 = 10000
' Set interface timeout to 10 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 50 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 10"
' Probe attenuation
' to 10:1.
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:COUPling 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 -0.4"
' Trigger level to -0.4.
myScope.WriteString ":TRIGger:SLOPe POSitive" ' Trigger on pos. slope.
' Configure the instrument for normal acquisition.
myScope.WriteString ":ACQuire:TYPE NORMal"
' Normal acquisition.
Capturing Data with the :DIGitize Command
The :DIGitize command captures data that meets the specifications set up by the
:ACQuire subsystem. When the digitize process is complete, the acquisition is
stopped. The captured data can then be measured by the instrument or
transferred to the controller for further analysis. The captured data consists of two
parts: the waveform data record, and the preamble.
