Select INPUT Path
These selection buttons are used to select
between AUX IN and RF A IN.
•
When AUX IN (100 kHz to 425 MHz) is selected, an externally
generated IF signal can be input that bypasses the down conversion
process of the PXI-1420; the signal is directed to the IF A OUT
connector.
•
When RF A IN (2.75 GHz to 26.5 GHz) is selected, the signal, after
being down converted, is directed to the IF A OUT connector.
