Power Ramp Setting
Time
The mobile transmitter output ramp should settle so that it complies with the power
mask (GSM Rec 11.10) by the time output level calibration is done in the
manufacturing process. The power mask is displayed in the Power Ramp screens.
Peak Carrier Power measurement method is not made to GSM Rec. 11.10. If you
need to make a measurement to this specification, go to the Power Ramp Summary
screen. The field in the top right-hand corner displays the Peak Carrier Power to
GSM Rec. 11.10. Refer to PWR RAMP: SUMMARY screen (item 5) for a
description.
Peak Carrier Power
Measurement,
Assumptions And
Algorithm
The algorithm for the Peak Carrier Power measurement is based on the use of a fast
sampler taking continuous asynchronous measurements of the power detected at the
RF IN/OUT port.
The sampler accumulates 75
µ
S sample bins containing the maximum power
observed during the period and the minimum power observed during the period.
Sampling rate is 10 MHz. The maximum and minimum values observed are based
on 750 individual samples within the period.
A trigger is provided at the middle of bit 0 of the burst. (When using RF Rise
triggering, the actual trigger may occur several bits earlier due to the ramp up of the
burst.) In response to this trigger, the following 6 sample bins (0 - 5) from the
sampler are saved and reported to the measurement processor.
