The Model CS-48-100 is a multi-channel, programmable current source. Developed for both semiconductor and digital superconductor electronics, it is computer-controlled and features 48 low noise current source outputs. Each source output has the capability to both set and read back currents and can be set to a zero current high Z mute state. Each of the 48 sources are optically coupled for control and are sourced from their own secondary winding for complete galvanic isolation. The device consumes a maximum of only 80 W and handles a maximum load current of 4.8 A total over all outputs. Operating over a range of 0-100 mA on each channel, the device features accuracy of +/-25 ?A. The mute state can be set thru a rear panel interlock or from the front panel button for maximum circuit protection. The unit can be mounted in a standard-sized rack.

Noise Location Package
Type HFDF
-
National RF’s Type HFDF high frequency location system is a proven noise hunting and location directional antenna system that allows you, in many cases, to walk right up to the source of High Frequency (HF) noise! Used by several power companies around the United States, professional noise hunters, and other communications specialists, the HFDF has located noise sources that emanated from pole power transformers, arcing electric fences, CATV in-line amplifiers, plasma TV screens, and even Marijuana grower’s heating lamps! The system incorporates several plug-in, tunable magnetic loop sensors of a proprietary National RF design, that cover the frequency range between 1.8 MHz and 55 MHz. The unit is packaged in a hand-held, lightweight metallic enclosure, with a pistol grip and a magnetic compass mounted on top. The compass is used to get magnetic bearings to the noise source, which may be plotted on a map to triangulate, and ultimately pin-point, the location of the noise source. In certain cases, our customers tell us that they have been able to walk right up to the interfering noise source and correct the situation on the spot!
