Description

Most practical, high performance optical spectrum analyzer on the market.

Fast

The OSA20 is the fastest optical spectrum analyzer of its kind with a maximum sweep speed of 2000 nm/s. It uses a fixed monochromator bandwidth of 20 pm and a fixed sampling resolution of 2 pm for all scans. This means every measurement is taken at the highest resolution and the highest accuracy. Sweep speed is determined solely by the choice of the sensitivity level: -55 dBm at 2000 nm/s down to -90 dBm by averaging over 380 scans with HIGH at 0.5 nm/s.

Accurate

The OSA20’s monochromator utilizes a renowned filter technology. The scanning filter has a 20 pm bandwidth, steep edges and low stray light. Power is integrated over 2 pm steps resulting in 225,001 data points for a 450 nm span. This allows for DWDM channel analysis down to 6.25 GHz spacing. The instrument has a high wavelength accuracy over the full wavelength range with ±10 pm specified over 1500-1640 nm.

Easy to use

The OSA20 is operated through its 12 inch capacitive touch screen with multi-touch gesture control, an industry first. This allows very fast navigation, scrolling and zooming in an intuitive manner. Keyboard and mouse control are also available through the USB interfaces.
