Advanced Optical Power & Meter, Benchtop, Dual Channel
The 2938-R dual channel high performance optical power and energy meter features a 7 inch, high brightness, touch screen and great improvements on the user interface. With the high bandwidth electronics design and high speed digital processing, up to 10 kHz rate measurement rate, time stamped, is achieved. Multiple graphics, color, and language settings are available. Advanced functions such as scaling, analog filtering, averaging, triggering, and pass/fail criteria with warning audio are available. Fast analog output allows integration with an external data acquisition equipment or signal analysis with an oscilloscope.
Ethernet, USB and RS-232 communication interfaces are supported. Data logging with up to 7 digits resolution and its compatibility with the powerful PMManager™ control software ensures obtaining the most comprehensive sets of measurements data.
The 2938-R comes complete with a calibration certificate, a handy quick start guide, a USB cable and a power cord.
