Appendix B: Performance Verification
Table B- 22: 10-bit Linearity, G Channel, Level 3 of 4
Linearity Lower limit G Upper limit
Resolution (Bits) 8 8
Max INL (LSB) -20.48 20.48
Max DNL (LSB) -0.5 0.5
Monotonic (Y/N) Yes Yes
41. From the TekScope application menu bar, select Top menu: Vertical > Offset
> Select Ch1 > enter -0.175 (Volts) in Offset box.
42. From the TekScope application menu bar, click on App software button.
43. From the VM5000 application menu bar, click the Run button to take the
linearity measurement.
44. Record the results in Table B -23.
45. Check that the results are within the upper and lower limits (Resolution
should read 8-bit).
Table B- 23: 10-bit Linearity, G Channel, Level 4 of 4
Linearity Lower limit G Upper limit
Resolution (Bits) 8 8
Max INL (LSB) -5.12 5.12
Max DNL (LSB) -0.5 0.5
Monotonic (Y/N) Yes Yes
46. Compute composite resolution: If the Resolution (bits) value in Tables B -20
through B -23 is the same, add 2 to the value and enter this value under
“Resolution (Bits)” in Table B -24. If the value for Resolution (bits) is not
the same for all tables, the Resolution portion of the performance verification
for this channel has failed.
47. Determine maximum INL: find the worst case (extreme) INL value from
Table B -20 to Table B -23 and enter the resulting value, or this value plus
the INL value from Table B -17, which ever has the largest absolute value,
under ”Max INL (LSB)” in Table B -24 on page B -39.
48. Compute maximum DNL: find the worst case (extreme) DNL value from
Table B -20 to Table B -23 and enter the resulting value under “Max DNL
(LSB)” in Table B -24 on page B -39.
