This field sets the output frequency of Audio Frequency Generator 1. Refer to the
AFGen1 Freq field description, on page 486
This field has two fields:
• the upper field sets the destination port for Audio Frequency Generator 1
• FM -RF Generator FM modulator
• AM -RF Generator AM modulator
• Audio Out -AUDIO OUT connector on front panel of Test Set
• the lower field sets the:
• FM modulation deviation if the upper field set to FM
• AM modulation depth if the upper field set to AM
• amplitude of audio signal (volts RMS) at the AUDIO OUT connector if upper field
is set to Audio Out
For testing mobile stations, the upper field is normally set to
field set to the desired FM deviation in kHz. Refer to the
description, on page 486
This field sets the output power of the Test Sets's transmitter (that is, the output
power of the Test Set's RF Generator). Refer to the
