Анализатор поляризации N7781C
HIGHLIGHTS
- High-speed operation up to 1M samples/s
- 1240 nm to 1650 nm operating wavelength range
- Typical 1.5° state of polarization (SOP) measurement uncertainty
- Robust, no moving optical parts
Due to its real time measurement capability of 1 M samples/s, the instrument is well suited for analyzing disturbed and fluctuating signals as well as for control applications requiring real time feedback of polarization information, for example in digital control loops in automated manufacturing test systems.
The built-in user interface allows a comprehensive analysis of the obtained measurement data and replaces the Polarization Navigator software that was required with the N7781B, the predecessor of N7781C. Programming uses a new SCPI command set and the instrument is addressed as a VISA resource. The instrument comes in a compact form factor of just one rack unit height, with LAN and USB interfaces.
