Optical Power Meter - Test Automation

Test Automation

Typical test automation features usually apply to loss testing applications, and include:

• The ability to set the unit to read 0 dB at a reference power level, typically the test source.
• The ability to store readings into internal memory, for subsequent recall and download to a computer.
• The ability to synchronize the wavelength with a test source, so that the meter sets to the source wavelength. This requires a specifically matched source. There simplest way of achieving this, is by recognizing a test tone, but the better way is by transfer of data. The data method has benefits that the source can send additional useful data such as nominal source power level, serial number etc.
