TX Power

This field displays the measured RF power of the carrier being transmitted by the mobile station. Four dashes (----) indicates that there is no carrier present to

measure. See “Measure” in the GPIB Command Syntax chapter of the E8285A Condensed Programming Reference Guide for programming command syntax.

A non-zero value would only be displayed in the connected state (that is, the

Connect annunciator is lit). The TX Power field is only displayed when the

Display field is set to Meas.

When the CALL CONTROL screen is displayed and the Test Set is in the connected state (Connect annunciator is lit), the mobile station’s transmitted carrier power is constantly monitored. If the power falls below 0.0005 Watts, the error message RF Power Loss indicates loss of Voice Channel will be displayed, and the Test Set will terminate the call and return to the active state (Active annunciator is lit).

NOTE:In order to ensure that the Test Set makes the correct decisions regarding the presence of the mobile stations’s RF carrier, the Test Set’s RF power meter should be zeroed before using the Call Processing Subsystem. Failure to zero the power meter can result in erroneous RF power measurements.

Refer to the "Display" field on page 223 for information on how to read measurement results from this field.
