CAUTION:

NOTE:

Requirements

Before performing any transmitter measurements, make sure that the power level applied to the RF IN/OUT port of the PCS Interface does not exceed the published limit. For CDMA base station signals this is 1 Watt (+30 dBm). You may have to use an external attenuator or directional coupler, depending on the power output for your transmitter. Signal levels greater than the specified maximum can cause damage to the test equipment.

The test procedures outlined in this section require that you have already configured the Test System as outlined in chapter 1, "Getting Started".

•You must have a means of turning on the base station transmitter with modulation.

•You must know the following about the base station and setup:

❒The base station channel number setting.
