Measure Linear Fidelity

1. Set the 1 dB and 10 dB step attenuators as indicated in
for the 4 dB from REF LVL setting.

3. Calculate the Linear Fidelity Error (LFE) as a percentage of
reference level (RL), and record the result in the performance
verification test record as indicated in column 9 of
LFE(% of RL) = 100 x (Actual Mkr Reading
/223.6 mV
For example, if the Ideal Mkr Reading is 89.3 mV and the Actual
Mkr Reading is 85 mV, the Linear Fidelity Error would be:
LFE
= 100 x (85 89.3) / 223.6
= 100 x ( 4.3) / 223.6
= 100 x 0.0192
= 1.92% of RL
