Type N (m) to BNC (m) adapter.
CAUTION
Support the directional bridge and low pass filter to minimize stress on
the spectrum analyzer’s input connector.
9. In the following steps, the two input tones will be approximately 3
dB above the reference level and will appear “clipped”. The marker
readings are still accurate, however. On the spectrum analyzer, press
