4-Channel PC-Controlled LC Adapter Optical Power Meter With Built-In Probe
The four-channel optical power meter is mainly composed of photodetector, amplifier, filter, analog-to-digital converter and microprocessor. In the measurement process, the optical signal is received by the photodetector and converted into an electrical signal, which is processed by the amplifier and filter, and then converted into a digital signal by the analog-to-digital converter, and finally processed and displayed by the microprocessor. This process ensures measurement accuracy and stability.
Characteristics and advantages
