Power Units
The MicroMeter is capable of displaying power readings in three different units. The user may toggle through these units by pressing
F1.
dBm (ABS) - This is an absolute (ABS) power measurement. It shows how much optical power is being received by the photodetector
in decibels referenced to a milliwatt (dBm).
dB (REL) - This is a relative (REL) power measurement. It shows the amount of optical power being received by the photodetector
relative to a user-defined reference power (i.e. "zeroing" the meter). If a reference value has been set, toggling to REL mode will show
the user how much optical power is being lost in the link.
µW (ABS) - This is an absolute (ABS) power measurement. It shows the amount of optical power being received by the photodetector
in microwatts, or millionths of a watt.
