4.7 Receiver Trouble

SETTING : After Initialize Agilent 8960, Test in EGSM, DCS Mode

Replace the Main board. ABB is

out of order.

Replace the C203

START

Check the signal level of

“

VOUTNORP” at C206. Is it a few

hundred mVAC?

Check the signal level at C207. Is

it a few hundred mVAC?

Yes

Check if the C203 is

short.

Yes

Check the contact state of

Receiver.

Replace Receiver.

Receiver will work properly.
