Step Procedure
9 As shown on Fig. (b), read the level of the current marker when ATT is set at 5dB. An error
is determined as calibrated ATT 5 dB value+∆ marker level.
10 Add a marker level corresponding to the calibrated ATT value when ATT is set as 10 to 90
DB (with 5 dB steps) and determine the error.
