6-7 Linearity Test Operational Testing for the MA24104A

6-10 PN: 10585-00020 Rev. C PowerXpert UG

e. Repeat the measurement for amplifier output levels of +35, +30, and +25 dBm.

8. Set up the test for the second 20 dB range as follows:

a. Remove the 10 dB K attenuator from in between the reference sensor and coupler, then connect

the reference sensor directly to the coupler’s coupling port.

b. Remove the MA24104A from the coupler and connect the 10 dB N attenuator between the coupler

and the MA24104A power sensor (see Figure 6-4).

c. Turn off the synthesizer RF output and perform a low-level Zero of both the Reference sensor and

the MA24104A.

d. Turn on the synthesizer RF output.

e. Set the amplifier output level to approximately 5 dB higher and then adjust the output level until

the MA24104A reads as close as possible to the value obtained in Step 7e.

9. Record data for the next 20 dB range:

a. Read and record the power indicated by the reference meter in Table 6-5.

Note The MA24104A power measured at +25 dBm will be used in Step 8e, below.
