Test Descriptions

TEST_41 - RTD RX/TX CDMA Quick General

Description

This is a CDMA quick test to verify the functionality of the mobile

stations’s receiver and transmitter. The test begins by making a mobile

station terminated call (service option 2). It then starts a FER

measurement at a mobile station received power of-104 dBm and then

moves to the transmitter test screen and measures Rho and maximum

power. The test then returns to the receiver test screen and reads the

FER. The test concludes by releasing the call.

1. A Service Option 2 (or 9 if parameter 19. RT Rate Set Selection

[0=9600 1=14400] is set to 1) call is attempted, unless a Service

Option 2 or 9 call is already connected. If the MSUT has not

registered, the call attempt may be unsuccessful and the error

message “Failed to establish a call in test <>” will be displayed. To

correct this problem, perform the CPD Registration test.

2. The RXD RF Level for Sensitivity parameter is retrieved and that

value is entered in the Sector A Power field. (This is performed in

two steps to prevent the call from being dropped).

3. The RXD Maximum Frames for FER parameter is retrieved and that

value is entered in the Max Frames field.

4. The FER test is turned on with a confidence limit of 95 %.

5. The FER Spec field is set to 0.5 %.

6. An FER test is triggered.

7. A Rho measurement is triggered and the results are displayed.

8. The maximum RF output power is measured and the test results are

displayed. (Refer to the TXD Maximum RF Output Power test for

this procedure).

9. The software waits for an GPIB interrupt to determine when the

FER test is done. The test times out and continues if the interrupt

does not occur within a period bounded by the RXD Maximum

Frames for FER parameter. If a timeout occurs, a timeout message is

displayed.
