Step 2:
Formula and Example are as follow:
Formula:
The current value (in dBm) –REF = the current value (in dB)
Example:
REF= –46.97dBm, the current value (in dB)= –13.79
Then the current value (in dBm) = (–46.97dBm) + (–13.79dB)
= –60.76dBm
Switch power measure of three types to power value.
Press “dBm/W” button to switch power measure (dB, dBm,
or Watt)
Change wavelength
Press “button” to change wavelength at 850nm, 1300nm,
1310nm, 1490nm, 1550nm and 1625nm.
Reference value setting
Press “dBm/W” button for a few seconds to set the current
power values as power reference value (in dBm measure)
