Test Descriptions

TEST_33 - TXD Waveform Quality & Freq Acc

Description

This test measures the CDMA waveform quality factor, ρ (rho), and a

suite of related transmitter carrier measurements as follows:

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 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. Power levels are set up according to values found in TIA/EIA/IS-98

standards.

3. The Rho suite of measurements is triggered.

4. When Rho suite of measurements are returned, the call status is

checked. If the call has been dropped, this test will start again. If

another call is dropped, the test will end and an error message will

be displayed indicating the call could not be maintained.

5. The following measurements are printed to the TESTS (IBASIC

Controller) screen:

• TXD Rho <Rho value>

• TXD Frequency Error <frequency error in Hz>

• TXD Static Timing Offset <timing offset in microseconds>

• TXD Amplitude Error <amplitude error in percent>

• TXD Phase Error <phase error in degrees>

• TXD Carrier Feedthrough <carrier feedthrough in dB>

Pass/Fail Limits Used

• 41. TXD Frequency Error (Hz)

• 47. TXD Rho

• 48. TXD Timing Offset (us)
