Operating Considerations
This is a priority control field. Accessing the RX TEST or TX TEST screen
overrides any changes made to this field in other screens.
SNR Operation

• The RF Generator and AFGen1 must be set up to provide the radio’s carrier. (AFGen1
is automatically turned on and off repeatedly during this measurement.)
• AFGen2 must be turned off.
• The radio’s receiver’s audio output must be connected to the AUDIO IN port (set the
AF Anl in field to Audio In.
