Manual Step Attenuator, DC to 18 GHz, 0 to 11 dB, 1 dB steps
8494B
Attenuator
The Keysight 8494B dc to 18 GHz manual step attenuator offers exceptional repeatability and reliability. Attenuation is provided in 1 dB steps from 0 to 11 dB. Precision gold-plated leaf springs ensure long life (over 5 million cycles) and very high attenuator repeatability (typically 0.01 dB). To improve measurement accuracy, NIST traceable data (SWR and attenuation) is available as Option UK6. Custom step attenuator/switch combinations are possible. The Keysight 11716A/B/C interconnect kits provide quick connection of Keysight 8494/5/6/7 1 dB and 10 dB step attenuators in series for greater dynamic range with 1 dB steps.

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.

Variable Power Supply
VS3
-
The VS-3 power supply is a very convenient portable, non-isolated “variable source” from 0 volts to 150 Vac or 0 volts to 150 Vdc and rated for up to 3 amps, thus the name VS-3. 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-3 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. A unique feature of the VS-3 is that it contains “Magnet Packs” on the back of the case. These “Magnet Packs” can support the VS-3 and allow it to “hang” from any magnetic metal surface. The VS-3 can be powered by our UPS system, eliminating the need for an extension cord. The ability to magnetically attach the VS-3 near the source of connection and eliminating the need for an extension cord makes the VS-3 a “must have tool” for technicians.
