c. Increase input amplitude by stepping attenuator in 10dB steps until CCA output is saturated. Verify

that signal amplitude on channel 1 is greater than 12Vp-p.

d. Remove clip E6 (green) from test point E6 and connect to E5.

e. Verify CCA output is saturated. Verify signal amplitude on channel 1 is greater than 12Vp-p.

D.5.11 .3.4 Bandwidth Test. Refer to para. D.5.12.4 for troubleshooting procedures.

a. Disconnect clip E5 from test point E5 on UUT. Channel 1 remains at E6 DOPP(-).

b. On test set, set switch S1 to SIGNAL GEN, set attenuator to 100 dB.

c. Turn on function generator.

d. Verify input voltage (CHANNEL 2) is 2.5Vp-p and attenuator is set to 100 dB.

e. Set signal frequency to 10KHz. Output readings should be equal or greater than 1 .75Vp-p.

f.

Set signal frequency to 50KHz. Output reading should be equal or greater than 2.5Vp-p.

g. Set signal frequency to 100KHz. Output readings should be equal or greater than 1 .75Vp-p.

h. Remove clip E6 (green) from test point E6 and connect to test point E5 DOPP(+).

i.

Repeat step d., e., f., and g. for DOPP(+) channel.

D.5.11 .3.5 Deenergize all test equipment and disconnect the UUT from the test fixture.
