Front panel inputs/outputs are: RF INPUT 50Ω [[Planar Crown interface]] (Compatible with K or type N connectors); EXTERNAL MIXER [[SMA connector]] (50Ω) , LO OUTPUT [[SMA connector]] (Provides access to the output of the 1st local oscillator at >+4 dBm. Must be terminated in 50Ω at all times); REF SIGNAL OUT [[SMA connector]] (100 MHz -20dBm phase locked to reference oscillator); and ACCESSORY IN (general purpose serial data port); PROBE POWER (Provides operating voltages for active probes). | Front panel inputs/outputs are: RF INPUT 50Ω [[Planar Crown interface]] (Compatible with K or type N connectors); EXTERNAL MIXER [[SMA connector]] (50Ω) , LO OUTPUT [[SMA connector]] (Provides access to the output of the 1st local oscillator at >+4 dBm.
