9KHz-3GHz Near Field Probe Is A Device Used To Measure Electromagnetic Signals. It Can Detect Electromagnetic Radiation In The Range From 9 Kilohertz To 3 Gigahertz And Operates Relatively Close To The Measurement Target. This Type Of Probe Is Commonly Used For Testing Areas Such As Radio Spect , Electromagnetic Compatibility And Radio Equipment. The Working Principle Of The Near-Field Probe Is To Measure The Signal By Receiving The Intensity Of The Electromagnetic Field. It Usually Consists Of A Radio Antenna And A Receiver That Converts Received Electromagnetic Signals Into Electrical Signals That Can Be Analyzed And Measured. These Probes Can Be Connected To Specialized Inst ents Or Measurement Equipment, Such As Spect Analyzers Or Oscilloscopes, To Obtain More Detailed Data And Graphical Representations. When Using A 9khz-3ghz Near Field Probe, You Need To Pay Attention To Keeping The Distance Between The Probe And The Object Being Measured Close To Ensure Accurate Measurement. In Addition, The Influence Of Other Electromagnetic Sources That May Cause Interference Should Be Avoided.In Short, The 9Khz-3Ghz Near Field Probe Is A Device Used To Measure Electromagnetic Signals And Is Mainly Used For Testing Radio Spect , Electromagnetic Compatibility And Radio Equipment.
