21. Record the level of fixed marker level in the Measured Data column in the per-
formance verification record sheet. Calculate the incremental error by following
formula and record the result in the Incremental Error in the column in the per-
formance verification record sheet.
Incremental Error (dB) = (current delta marker level) - (previous delta marker
level) + 10 dB
22. Repeat steps 19 through 21 for each value of the 10 dB step external step attenu-
ator is listed in the Table 5-15.
