Keysight N7747C Optical Power Meter with 800 nm to 1700 nm Wavelength Range and +10 dBm to -110 dBm Power Range for Accurate Measurements

With actively cooled InGaAs detectors and optimized high-performance analog electronics, these instruments provide the lowest level of noise and drift to deliver a very low and stable zero-signal level. The exceptional linearity and low polarization dependence ensure peak accuracy across the full power range.

Features an analog output with linear feedback for alignment applications, including a standard BNC connector with 0 to 2V output. This combination of highest sensitivity and analog voltage output creates a powerful solution for probe and fiber alignment operations and other optimization routines where detecting and tracking weak initial signal levels in real-time is critical.

The N7747C is equipped with two power sensor channels, while the N7748C provides four power sensor channels. Each port accepts one of the proven 81000xI connector interfaces to adapt to common fiber-optic connector standards, supporting a wide range of connector types.

Access the graphical user interface directly through your web browser via LAN or USB connection. No software installation required - simply connect the instrument via USB to a PC, and it appears as a new drive with a shortcut that opens the interface in any modern browser.

The N7747C and N7748C benefit from the N77-C family's common trigger concept and modern, browser-accessible user interface. Features include high-speed measurement data acquisition, faster data interfaces, dual-ported RAM for uninterrupted simultaneous measurement and readout, and fast power range switching to minimize delays in measurement processes and post-processing.
