Q1: How is output power adjusted on the FCST080208?
A1: The instrument features a continuous 15 dB power adjustment range from -5 dBm down to -20 dBm with a fine resolution step of 0.05 dB, allowing operators to set precise signal levels directly on the device
Q2: What is the benefit of the automatic wavelength identification feature?
A2: When paired with an FCST power meter supporting auto-ID, the light source sends encoded wavelength information over the fiber link
Q3: Can this light source output two wavelengths simultaneously?
A3: Yes. The FCST080208 supports both single-channel and dual-channel output modes, allowing users to select single-wavelength or dual-wavelength testing depending on project needs
Q4: How long does the battery last during field operations?
A4: Equipped with a 4000mAh rechargeable lithium battery, the unit supports at least 25 hours of continuous operation on a full charge
