Measuring the Range of Open Loop Output Power
Measuring the Range of Open Loop Output Power
The Test Set measures the range over which the mobile-station-under-test
(MSUT) can adjust its Effective Radiated Power (ERP) in response to the power
level it receives from the Test Set. This test is performed according to TIA IS-98
standards, except that Îor is set to −35 dBm/BW instead of the recommended
value of −25 dBm/BW for the first test.
Test Prerequisites
•
The Channel Power measurement should be calibrated at least as often as the following
conditions arise:
• 5 °C change in operating temperature
• Power cycle
• Daily
See "Calibrating Channel Power Measurements" on page 29 if necessary, and
then return to this procedure.
NOTE:
The following procedure assumes that an instrument PRESET will be performed as part of
setting up a call. This clears all settings from other tests that may affect the accuracy of this
test, and allows the procedure to begin from a known instrument state.
