Control Fields for CDMA Measurements

Input Atten

This field controls the RF attenuators of the Test Set. If an ADC Overdriven message is displayed at the top of the screen while making measurements, increase the attenuator setting until the message is no longer displayed. This is the coarse level adjustment for the signal level into the CDMA analyzer. Fine level adjustment is performed using the Gain field.

See “Gain” on page 159 for more information.

The Input Atten setting does not affect, and is not displayed with, the average power measurement.

Input Port

This field selects which Test Set port to use as the RF input. This field is not displayed when measuring average power, since you must use the RF IN/OUT port to measure average power.

Instrument Damage

To prevent instrument damage, do not exceed the maximum power level labeled at the connectors on your Test Set. The ANT IN connector is for measuring low level RF signals. High level (>60 mW) transmitter signals must be measured using the RF IN/OUT port.

Lvl

This measurement displays the relative level of the selected Walsh channel when compared to the total power in a 1.23 MHz bandwidth centered around the Tune Freq setting. The measurement is displayed when the code domain analyzer’s main controls Measurement field is set to Power or Fast Pwr. This function is appears as Marker Lvl for the IS-2000 option. See “Marker Lvl” on page 162
