Notes:
1. <Sample>
Sample sets the maximum measuring period in unit of frame.
When the number of the measured frames is reached to the value, the mea-
surement ends.
2. <Confidence Level>
Confidence Level sets the judge threshold for the reliability level.
When the Measure Stop Mode is On and the reliability level is reached to
this value, the measurement ends.
3. <FER>
This sets the specification of the FER.
The MT8801C displays the reliability level to this FER value.
4. <FER Upper Limit>
When the Measure Stop Mode is On and the FER is reached to this value,
the measurement ends.
5. <User Cal Factor>
When there is a loss in the cable between the mobile-station RF input and
the MT8801C RF output, set the User Cal. Factor to convert the BS Output
Level to the input level of the mobile station.
For example, when there is a 5-dB loss, set the User Cal. Factor to 5 dB.
