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)

Program mode:

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.
