Operating Precautions
Do not exceed the maximum ratings listed below or permanent damage to
WARNING
the mixer will result.
RF input power
Use the following parameters:
– CW: No greater than 20 dBm
– Peak pulse: No greater than 24 dBm at <1 μs
See the gain compression values for each model mixer. Use an appropriate
waveguide attenuator if the output power of the unit under test exceeds the gain
compression value.
LO input power
LO input power is set by the internal signal analyzer LO alignment. However, the
LO input must not exceed 20 dBm.
Always use a high quality low loss SMA cable since this will allow the longest
cable length, and prevent damage to the mixer SMA female connector.
Electrostatic discharge
When installing the mixer, always connect the LO/IF SMA cable to the signal
analyzer BEFORE connecting to the mixer. This will minimize the danger of an
electrostatic discharge damaging the mixer diodes.
Connect only one mixer at a time
The automatic LO adjustment and mixer ID process assumes only one mixer is
connected to the analyzer's USB and SMA EXT MIXER connections.
