EXFO FVA-60B ATTENUATOR
Lab and Field Versatility
This portable variable attenuator performs just as well in a laboratory environment as it does in the field. Superior specifications make it the variable attenuator of choice for a number of applications. For lab or fieldwork flexibility, choose the FVA-60B.
Up to 65 dB attenuation
Typical 2.5 dB insertion loss
Automatic attenuation sequence with Program mode
Standard Universal Interface
Three attenuation display modes
Absolute (including insertion loss)
Relative (in reference to 0.00 dB level)
x + b (arbitrary value)
Cycles through a repeatable sequence of up to 60 attenuation steps, pausing for one second or up to 60 hours at a time. The Program mode is particularly suited to accelerated bit-error-rate (BER) testing.
Fourteen available wavelengths
Matches your source wavelength to the nearest 10 nm for unbeatable accuracy.
Variable scanning speed
Scans the complete attenuation range at four different speeds according to the selected step size (0.05, 0.20 or 1.00 dB/step and variable step size).
Remote Control Capability
Operate the FVA-60B remotely from your PC using the standard RS-232 interface and control codes. Program software solutions are adapted to your testing needs.
Three-Way Powering Goes a Long Way
The FVA-60B features three complementary power sources for extended operation: a rechargeable NiCd battery, a 9 V alkaline backup battery and an AC adapter/charger for continuous operation.
High-quality optical components make the FVA-60B Variable Attenuator the standard for performance and flexibility. EXFO’s computer-assisted calibration techniques deliver remarkable specifications:
± 0.15 dB linearity
0.05 dB resolution
± 0.10 dB repeatability
The FVA-60B enables consistent operation in various manual or automated testing situations.
