Detailed introduction to EXFO FVA-60B：
Applications
BER testing
System tolerance to signal attenuation
Key Features and Benefits
Low backreflection of>40 dB
Automatic attenuation sequence with Program mode
Up to 70 dB attenuation
±0.15 dB linearity from 2.5 to 70 dB，0.05 dB resolution and±0.10 dB repeatability
Details
This handheld variable attenuator performs just as well in a laboratory environment as it does in the field.Superior specifications（±0.15 dB linearity from 2.5 to 70 dB，0.05 dB resolution and±0.10 dB repeatability）make it the variable attenuator of choice for various applications.For lab or field work flexibility，choose the FVA-60B Variable Attenuator.
