Agilent/Keysight N7749C Optical Power Meter Mainframe

The Keysight N7749C is an optical head interface designed to control two or four remote optical power meter heads from the 8162-C series. This instrument provides flexible data acquisition capabilities, enabling continuous sampling with internal or external triggering, and logging power values with dual 1M sample buffers per head. It facilitates high-test throughput with uninterrupted simultaneous measurement and readout, minimizing overhead for repetitive tasks. The N7749C integrates into various test environments through its LAN and USB interfaces, offering a built-in web-browser GUI and supporting the SCPI command set common to Keysight optical power meters. An analog output port is available for automated alignment processes, providing direct feedback proportional to optical signal power or logarithmic over decades of power levels.
