1. Calibration method
Turn on the digital waveform calibration function, use the logic analyzer testing line
or probe of the oscilloscope and connect the output signal of the analog channel to
an oscilloscope or a multimeter.
2. Calibration step
(1) High level calibration
Press Calibration High volt and read the DC voltage level from the oscilloscope or
the multimeter when the output is high level of 7.5V, input the value to DG3000
and press YES to finish the calibration.
(2) Low level calibration
Press Calibration Low volt, and read the DC voltage level from the oscilloscope or
the multimeter when the output is low level of -4V, input the value to DG3000 and
press YES to finish the calibration.
If there are input errors or other cause and results in error of the output voltage
after the calibration, press Set to Default to restore the level to factory default.
