2 System Operation
2.1 Getting Started
First you have to install the 841-P-USB software on your computer, along
with the USB drivers, they are found on the CD included. Until the COM
port is chosen, all the other menu options are grayed out. To start, you must
tell the 841-P-USB software which port the 841-P-USB will use. To link the
841-P-USB to the COM port, click
Ctrl / Communication / Connect
. A
dialog box appears so that you can select the appropriate serial port (COM 1,
COM 2, etc.). Once you have selected a port, click
OK
. Now you are ready
to adjust the settings.
2.2 Making a Measurement
This section will show you the fastest way of making a laser power and
energy measurement with the 841-P-USB and a Newport 818P Series High
Power or 818 Series Low Power Detector.
The 841-P-USB Virtual Power Meter automatically recognizes all Newport
low-power and high-power detectors terminated with a 15-pin (DB15)
connector. All calibration and technical data required for optimum operation
of the detector will be automatically downloaded from the EEPROM in the
DB15 connector. This data includes sensitivity, model, serial number,
version, wavelength correction factors, and time response. The 841-P-USB
must be disconnected from the PC before connecting a new detector to it in
order to prevent any loss of data from the detector’s EEPROM.
Quick power measurement procedure:
1- Install the power or energy detector head on its optical stand.
2- Slide the connector latch to the right to unlock the connector.
3- Connect an 818P Series High Power Detector, or 818-XX/DB or 918D
Series Low Power Detector into the 841-P-USB using the DB15 Detector
Input Connector. Connect the detector into the virtual meter
BEFORE
connecting the meter to your PC.
4- Slide the latch to the left to lock the connector into place.
5- Connect the USB cable to your computer.
6- If you are using an 818-Series Low Power detector, to obtain
measurements in dBm, select Settings / Power Unit / dBm.
