Power Meter Mode
For 86141B/86144B/86146B only
Power meter operation is an operation mode available on the 86141B/86144B/
86146B instruments. Power meter mode displays the broadband power of the
input light over time. The input light is directly connected to the instrument’s
photodetector. This bypasses the internal monochromator and prevents any
filtering by the resolution bandwidth filters. With power meter mode, you can
perform the following:
• measure total power of broadband light sources
• monitor power as a function of time
Monitoring power enables you to observe both long and short term drift and to
perform real-time adjustments. Power meter mode places the instrument in
the following settings:
The input light is connected to the front panel Photodetector Input connector
for measurement. The front panel Monochromator Input and Monochromator
Output connectors are not used in power meter mode.
