Test Descriptions

TEST_04 - TXA RF Power Output

NOTE

This test will not run if all three of the following conditions are true:

1. The test set is an Agilent 8924E.

2. The test set does not include a spectrum analyzer (hardware Option

012).

3. Parameter 21 is set to YES.

If any of these conditions is not true, the test will run.

Description

This test measures the output power of the mobile station’s transmitter

into a

50-ohm load. The power is measured at the antenna terminals of the

mobile station. This test is performed at the nominal supply voltage.

This test can also be performed at the high and low supply voltage

settings if an GPIB programmable power supply is configured into the

test system and parameter 20. RT Test at Extreme Settings [0=no

1=yes] is set to 1. See“TEST_13 - TXA Current Drain” on page 36 for

details on configuring an GPIB programmable power supply.

Output power can be expressed in dBm or watts by appropriately

setting parameter 36. TX Units for Pwr Meas [0=dBm 1=Watts].

Pass/Fail Limits Used

• 26. TXA Output Power at Level 0 (dBm)

• 27. TXA Output Power at Level 1 (dBm)

• 28. TXA Output Power at Level 2 (dBm)

• 29. TXA Output Power at Level 3 (dBm)

• 30. TXA Output Power at Level 4 (dBm)

• 31. TXA Output Power at Level 5 (dBm)

• 32. TXA Output Power at Level 6 (dBm)

• 33. TXA Output Power at Level 7 (dBm)

NOTE

Normally, all power levels are tested; however, parameter 44. TXA

Output Power Levels Tested [BWD #] allows you to select only the

levels you want tested.
