RF connections
The calibration unit provides two RF connectors (numbered 1 to 2), to be connec-
ted to the test ports of the analyzer. The connector type is the same for all RF
ports of a calibration unit.
The maximum RF input power of the calibration unit is beyond the RF output
power range of the analyzer. If the device is directly connected to the test ports of
the analyzer, there is no risk of damaging the calibration unit.
