Atec Exfo-FVA-60A-B - Manual (Page 2)

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.
FVA-60 B
Total Flexibility
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).
KEY FEATURES
Accurate system loss simulation
Return loss of > 40 dB
RS-232 computer interface for
custom applications
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.
Exceptional Specifications
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 from 2.5 dB to 65 dB
0.05 dB resolution
± 0.10 dB repeatability
Multiple Applications
The FVA-60B enables consistent operation in various
manual or automated testing situations.
BER testing
System testing and acceptance
Power meter calibration and verification
