Variable Fiber Optic Attenuator
-
Variable fiber optic attenuator could help simulate distance or actual attenuation in the fiber optic testing work by inserting a calibrated attenuation into the link. By using the variable fiber optic attenuator, technicians could verify the power margin received by testing the fiber optic link power budget. Variable fiber attenuator can help user vary the light power injected from a light source into the optical fiber. Important parameter of variable fiber attenuator include its insertion loss, reflection loss and attenuation range.

Variable Transformer DC Power Supplies
-
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with a Variable Transformer (also known as variac). The Variable Transformer can be adjusted manually or with a motorized control. The AC input power can be single phase or three phases. With single phase AC input, the DC output ripple is very high (50%). With three phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three phase AC input instead of single phase.

Fixed Attenuator
FAXE
-
Fixed Attenuators are waveguide components for introduction of some particular attenuation value in to the waveguide network for signal leveling or reflection compensation. The attenuators have two types of design: with resistive plate in the waveguide diagonal plane or using coupling technology. The FAXE 3, 6, 10, 15, 20, 30 dB attenuators are available in waveguide bands from 18 through 225 GHz. The FAXE Fixed Attenuators can be used as laboratory Standards against which other instruments or devices are calibrated in case the parameters of these Fixed Attenuators are stable enough and were measured with appropriate accuracy.

Variable Power Supply
VS-10a
-
The VS-10a power supply is a light weight, portable, non-isolated “variable source” from 0 volts to 150 Vac or 0 volts to 150 Vdc and rated for up to 10 amps, thus the name VS-10a. It is comprised of an illuminated voltmeter that reads to the first significant digit, AC variable system output voltage, DC variable system output voltage, logic output voltage and one sense (continuity) contact monitoring points. Banana jacks for connection of test leads are spaced at intervals that allow the use of dual banana test plugs if desired. The VS-10a is protected by two levels of overcurrent protection; AC input, and ground fault protection by a GFCI. All circuitry is housed inside a custom designed case made from 16 gauge steel. An Internal fan dissipates heat buildup and exhaust through louvered side vents built into the case. The carrying handle is designed with a “spring return to rest” position and is padded for comfort. The case has been sized for optimum portability and is balanced from the handle during transportation. The case has a powder coated finish that is scratch, chemical and weather resistant. Rubber padded feet support the case when in the upright position and a convenience receptacle is located on the side of the case.
