Measuring Demodulation of Forward Traffic Channel with AWGN

The Test Set performs "Demodulation of Forward Traffic Channel in Additive
White Gaussian Noise" as described in TIA IS-98, "CDMA Receiver Minimum
Standards."

During this test, FER is measured as the Test Set provides various data rates to the
mobile-station-under-test (MSUT) with the Test Set’s AWGN generator turned
on.

Test Prerequisites

Determine Cable Path Loss

When using cables to connect the equipment, the path loss for the cable(s) should
be determined. The Test Set can be used as a source to measure path loss.

Refer to

"Correcting for RF Path Loss" on page 41

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.
