Highlights

Large-area detectors compatible with the N7749C

The 5mm detector area on Keysight's latest optical power heads allows flexible placement of the remote optical power meter, which is then connected to the N7749C. The wide choice of adapters allows input from popular fiber connector types, bare fibers or open beams. The magnetic D-shaped adapters allow rapid removal and replacement without twisting attached fibers.

N7749C interface for two or four optical power heads

  • Controls the remote heads
  • Sample averaging times ranging from 100 µs to 10 s for all heads
  • Readout over LAN and USB interfaces with built-in web-browser GUI
  • SCPI command set common to Keysight optical power meters
 
  • Power values logged with dual-1M sample buffers for each head, to sample continuously with internal or external triggering
  • Uninterrupted simultaneous measurement and readout minimize overhead time for repetitive measurements
  • Family-wide, common trigger concept

Analog Output Port Perfect for Automated Alignment

  • Direct feedback for optimization processes like fiber alignment with analog voltage outputs, at the remote head itself and from the N7749C front panel
  • Either linear proportional to the optical signal power or logarithmic over decades of power levels
