Result of the measurement in progress
The power measured by the power meter is displayed in large characters, in the units
selected in the S
• the mode of transmission of the signal measured: continuous (CW) or modulated
to a frequency of 270Hz, 330Hz, 1KHz, or 2KHz.
• the wavelength of the signal measured.
• the reference level expressed in dB.
• the level of Attenuation Compensation.
Table of results
For one and the same fiber, the power meter displays a table of 9 results corresponding
to the different possible wavelengths. The table shows the power measured in dBm, the
relative power (in dB) and the reference level in dBm (if units = dB), together with the
mode.

Auto (the sources emit on determined frequencies to enable the power
meter to detect the wavelength used automatically)
Twintest (cyclical emission on all available wavelengths for a few seconds
on each wavelength), compatible with the Viavi OLP 5/6/15/16/18.
CW (continuous emission)
- either the nominal value: -3.5 dB
- or an attenuation of -3 or -6 dBm, with regard to this nominal value, to get
a power of 6.5 dBm or of 9.5 dBm.
For all the other modes (270Hz / 330Hz / 1kHz / 2 kHz / Auto / Twintest),
select one of the following emitted power: -12.5 , -9.5, -6.5 dBm.
