APPENDIX A
CHARACTERIZATIONS
1. Test Report Data
a. Record the test report values for the equipment listed in table A-1.
b. Use values in table A-1 throughout the entire procedure.
NOTE
If there is not an AC/DC difference test report value
(specification) at the frequency of interest (fi) above 1 kHz,
interpolate the specification of interest (Si) between the higher
frequency (f higher) and lower frequency (f lower) using the higher
specification (S higher) and the lower specification (S lower) as
S

If there is no test report value at the frequency of interest
below 1 kHz, use the test report value at the frequency closest
to the frequency of interest.
