6.7 Frequency detection
When use tone detection function, following requirements have to
be taken into account:
For A: Tone detection will be effective only with measurement
range between +6 ~ -40dBm.
For C:
Tone detection can be worked only with measurement range
between +26 ~ -20dB, because the detected frequency will be unstable
when the power is weak.
How to act tone detection on Power Meter?
Connect power meter with its same serials light source SUN-LS200.
Output frequency from MATCHED optical light source: Press
emerge light from the unit, press
MATCHED light source will output frequencies of 270Hz, 330Hz, 1KHz,
2KHz accordingly, which will be shown on the upper right of the LCD in
MATCHED light source. In the mean time, the power meter will detect
the corresponding frequency automatically from MATCHED light source.
Please refer to below figure (6-32) for better understanding:
