μW LO output (downconverter)
The signal at this connector on the downconverter can drive the comb
generator of an external mmWave harmonic mixer.
When the downconverter is in source mode this connector is the output.
•
Frequency range: 2.4 to 6.8 GHz in 600 MHz steps
•
Output power (2.4 to 6.6 GHz): 0 to +16 dBm
•
Output power (7.2 to 25.8 GHz): 0 to +10 dBm
The frequency range is 2.4 to 25.8 GHz if the LO frequency is entered
manually.
•
Output impedance: 50
Enabling
Press the softkey, then the
Freqs
Entering mm band
Press the softkey, then the softkey for the band that includes the
mm Band
input frequency. This enables the donwconverter to accept and input
frequency entry within the selected band.
Entering LO frequencies
A LO frequency between 2.4 and 25.8 GHz can be entered with the
softkey. If a LO Frequency is entered the down converter does not calculate
and display Input, mm LO, or IF frequencies.
