Performance Verification
23. On the Tektroni
x FCA/MCA3X00 Series instrument, push the Input A button
and set the input attenuation to 1X.
24. Reset the Trig
ger value to that noted in step 14, the 1X Trigger Level
Uncertainty at 0 V value.
25. Push the Sav
e/Exit button to save the change and return to the Numerical
Analysis display.
26. Repeat step
s 20 and 21, entering the result in the test record as 1X Just
Becomes Inaccurate.
27. Move the in
put cable and attenuator stack to the Channel B input.
28. Repeat steps 9 through 26 for Channel B.
29. Now that the measurements have been made, perform the calculations shown
at the bottom of the Front End Characte ristics Worksheet. The letters in the
calcula
tions show which reference (Ref) line to use.
If you are using the spreadsheet version of the test record, these calculations
are don
e for you as you enter the measurement results.
