Check Offset Accuracy - Tektronix MSO70000C/DX Technical Reference

Check offset accuracy

MSO70000C/DX, DPO70000C/DX, DPO7000C, MSO5000/B, DPO5000/B Series
Gain Accuracy = ((Vdiff- VdiffExpected)/VdiffExpected) × 100%
d. Enter Gain Accuracy in the worksheet and in the test record.
10. Repeat tests at 1 MΩ impedance as follows:
a. Set the calibrator to 1 MΩ output.
b. Push the front-panel Vertical V menu button.
c. Set the Termination to 1 MΩ
d. Repeat steps 8 through 9.
11. Repeat steps 7 through 10 for all vertical scale settings in the test record.
12. Repeat the procedure for all remaining channels:
a. Push the front-panel button to deselect the channel that you have already
tested.
b. Push the front-panel button to select the next channel to be tested.
c. Move the DC voltage source connection to the channel input to be tested.
d. Starting from step 3, repeat the procedure until all channels have been
tested.
13. Press the Menu Off button.
This test checks the offset accuracy.
