Injection Transformer
J2101A
-
The injection transformer is presently the prevalent method for connecting the network analyzer to the circuit being tested, and is primarily used for control loop stability measurements. The goal of the transformer is to inject a signal into the control loop being measured, without impacting the performance of the loop. In order to accomplish this to a reasonable degree, The transformer is isolated and therefore is capable of floating on a high voltage, such as a Power Factor Corrector (PFC), which is often close to 400VDC. Measuring voltages that exceed the voltage rating of the FRA inputs require attenuation probes.

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!
