Mobile Station Audio Out Impedance
If the mobile station’s speaker is disconnected when using the manufacturer’s
special fixture, the user must ensure that the proper load impedance is applied to
the audio output of the mobile station. The special fixtures supplied by the
manufacturer of the mobile station may or may not terminate the audio output in
its proper load impedance. Refer to the manufacturer’s documentation for
information on the termination supplied by the special fixture.
If a load impedance must be supplied, then it can be placed across the AUDIO IN
connector. Refer to
"AUDIO IN" on page 563 and chapter 5, "AF Analyzer
Screen," on page 99
, for further information.
600 Ohm Impedance
Some industry standards require the audio out of the mobile station to be
terminated in 600 ohms for testing purposes. The AUDIO IN connector of the
Test Set can be terminated in 600 ohms internally. Refer to
"AUDIO IN" on page
563
and chapter 5, "AF Analyzer Screen," on page 99, for further information.
