Example Program

Example Program
This program demonstrates the basic command structure used to program the
oscilloscope.
• Line 10 initializes the instrument interface to a known state.
• Line 20 initializes the instrument to a preset state.
• Lines 30 through 50 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.
• Lines 60 through 90 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.
• Lines 100 through 120 configure the instrument to trigger at -0.4 volts with
normal triggering.
• Line 130 configures the instrument for normal acquisition.
