Product Overview
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 several applications. For lab or fieldwork flexibility, choose the FVA-60B.
| Key Features |
| Up to 65 dB attenuation |
| Typical 2.5 dB insertion loss |
| Automatic attenuation sequence with Program mode |
| Standard Universal Interface |
| Benefits | |
| 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: | The FVA-60B features three complementary power sources for extended operation: a rechargeable NiCad 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 0.05 dB resolution ± 0.10 dB repeatability |
| 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 Optical margin analysis System loss simulation Field, manufacturing and R&D applications |
