10.9 Dynamic Level Accuracy
10-58
(13) For each set level, calculate the dynamic level error using the following formula:
(dynamic level error) = (measured value) - (Offset value)
NOTE:
The offset value is a attenuator error at the reference point.
(Offset value)=(calibration factor of the attenuator at the reference point)-(calibration
factor of the attenuator at the set level)

Dynamic level accuracy at 3.8 GHz
(14) Press [CENTER], [3], [.], [8] and [GHz] to set the center frequency to 3.8 GHz.
(15) Press [MRK], [3], [.], [8] and [GHz] to set the marker to 3.8 GHz.
(16) Set the step attenuator to 20 dB.
(17) Press [CAL] and {NORMALIZE(THRU)} to do normalization.
(18) Set the step attenuator to 10 dB.
(19) Read out the marker level.
(20) Repeat steps (18) and (19) on each set level listed on Table 10-4.
(21) For each set level, calculate the dynamic level error using the following formula:
(dynamic level error) = (measured value) - (Offset value)
NOTE:
The offset value is a attenuator error at the reference point.
(Offset value)=(calibration factor of the attenuator at the reference point)-(calibration
