Notes
The torque for the SMA cables and adapters should not exceed 8 in-lbs.
The LO/IF connection between the mixer and the signal analyzer must be
in place before the USB cable from the mixer is connected. Connecting
the USB cable automatically triggers the LO adjustment, and if the LO/IF
cable is not connected the adjustment will not complete and an error will
occur.
When a connection is made, the green LED on the mixer lights up
indicating that the mixer has power and the processor inside the mixer is
running. The spectrum analyzer is automatically switched to external
mixing mode, and the mixer model number and mixer option are used to
set the start and stop frequencies for the mixing band.
The 10 MHz signal from the signal analyzer provides the LO signal to the
mixer's second converter in the dual conversion path.
