What is the difference between video output & recorder output feature in N1911A/N1912A?

The video output port produces identical DC voltage waveform representing the RF signal that has not gone through any internal signal processing in the power meter. This unprocessed signal can be shown by the oscilloscope in time base measurement mode by connecting the BNC connector from the rear panel of the power meter to the oscilloscope input.

The recorder output port produces processed DC voltage corresponding to the RF power and this signal can only be measured by the Digital MultiMeter/ Digital Volt Meter for recording purpose.

The advantage of video output over recorder output is the capability for users to monitor the RF waveform source on the oscilloscope when performing power measurement. This provides a visual aid to ensure that the correct incoming signal is being measured.
