Limit Values
The Limit Values table section defines upper limits for the absolute output power of
the mobile station, measured at zero frequency span and with a filter bandwidth of
30 kHz.
Enable Switches the limit check at the frequency or power level on and off
Power Lvl. User-defined MS output power level (not necessarily identical with the
GSM power control levels). The CMU offers considerable flexibility with
regard to the limit line definition: They are specified at four fixed, GSM-
specific frequency offsets and up to 10 arbitrary MS power levels (see
Table 4-3 ). For measured MS powers between the power levels, the
limits are determined by linear interpolation.
