2938-R Advanced Optical Power & Meter, Benchtop, Dual Channel

The all new 2938-R (P/N 7Z01706)  Dual Channel High Performance Optical Power and Energy Meter has significant number of improvements over 2936-R, one of the fastest optical meters available in the market. Up-to-date Android based OS and 7 inch high brightness touch screen add 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 currently, and potentially up to 100 kHz with a future firmware update. Multiple graphics, multiple color settings, and multiple 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. USB and RS-232 communication methods are supported currently, and Wi-fi and ethernet will be added in the future firmware upgrade, which can easily be done by the user.. Extremely easy logging feature and its compatibility with the powerful PMManager^TM 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.

Most Advanced Optical Power and Energy Meter in The Market

The all new 1938-R and 2938-R power meters, inheriting most of the advanced functions available in x936-R series, have been redesigned with the up-to-date CPU, touch screen, Android OS, and high bandwidth electronics boards. The new power meters are one of the most powerful, fast, and versatile power meters in the market. Beautifully designed user interface allows unprecedent speed of measurements along with various graphical and numerical presentation of the data.

Ideal for High Speed, Modulated Light Measurements

Depending on the range, x938-R power meter has up to 200 kHz bandwidth for the 818, 918D, or 819C/D series photodiode detectors. It allows up to 10 kHz rate, time-stamped data logging to the on-board memory or an external USB memory, showing more details about the characteristics of the light source. To fully utilize the high bandwidth operation, x938-R has analog output where the raw signal can be directly sent out to an oscilloscope or a DAQ (data acquisition) board. In addition, when connected to a 919E series pyroelectric sensor, every single pulse up to 25 kHz can be logged.

Full Color 7” Touch Screen with Intuitive User Interface

1024 x 600 pixel high brightness, full color 7” touch screen provides the feel of using a tablet, making the menu maneuvering at one’s fingertip. With the clearly legible display, various selections of information and graphs are visually appealing and easy to read even at a distance, making the instruments more helpful in complex measurement situations. The user interface is beautifully designed so that advanced features such as advanced graphing, mathematical functions, offsetting, scaling, laser tuning, logging can easily be accessed and utilized during measurements and experiments.

Time-stamped Data Acquisition at up to 10 kHz

Even though x936-R’s 10 kHz data measurement rate was already impressive, the new x938-R optical power meters made an improvement by adding a time stamp to the data, thereby knowing exactly when the measurements were taken. The log files can be easily set up and recorded in either the 2 GB on-board memory or on a USB thumb drive. Once the log files are created, the text data or the graphics file can be viewed within the instrument.
