Features

Ideal for Measurement Automation and Production

The all new 841-PE-USB Power & Energy Meter utilizes a PC as a powerful virtual power meter control system. When the equipment space is tight or you need to control multiple power meter channels, 841-PE-USB is an ideal solution. It not only has a USB output, but it also has a 0 - 1 V analog output. Installation of the application is simple and takes care of the USB driver installation.

PMManager™ Application Software

PMManagerTM is a powerful application software controlling and taking measurement data. It turns a PC into a laser power multi-channel analysis workstation. The PMManager software features include: extensive graphic display of data, advanced measurement processing, data logging for future review, printing of graphs and data, and the ability to connect additional devices during active measurements.  Please see the PMManagerTM Tutorial for more details regarding its capabilities.

Directly Access All Detector Parameters

All detector parameters are directly accessible from PMManager. Major parameters are available on the detector information window, and further functions are available by clicking ‘Functions’ button.

Extensive Graphic Displays

Various graphics displays are available in PMManager such as Line Plot, Histogram, Bar chart, and Simulated Analog Needle. Multiple data sets on one graph or separate graphs on the same screen are possible.

Data Logging for Future Review

  • Can be displayed graphically or saved in text format 
  • Log data based on the time interval or on the number of data points 
  • Easily exported to an Excel spreadsheet

COM Object

The PMManager software package also includes a COM object, which allows system integrators to integrate the measurement expertise of Newport equipment with in-house legacy analysis packages.

Demo client applications in VB.NET 2010, VC#.NET 2010, MatLab, and LabVIEW 2013 are provided with the PMManager installation and can be found in C:\Program Files\Newport\PMManager 3.xx\Automation Examples\Com object. A console application is provided as well.

Advanced Measurement Processing

  • Power/Energy Density, Scale Factor, Normalize against a reference 
  • Multi-channel comparisons 
  • User defined mathematical equations: channels A/B, (A-B)/C etc. 
  • Log every point at up to 10 kHz with Pyro sensors in binary mode
  • Log every point at up to 1 kHz with Pyro sensors in ASCII mode
  • Position & size measurement with PEPS sensors

Regarding 841-P-USB and 842-E-USB

The 841-P-USB and 842-E-USB virtual power meters are being phased out.  Please note that the new 841-PE-USB employs a completely new design and it is not compatible with 841-P-USB and 842-E-USB.
