Abstract
The present invention relates to an apparatus for measuring low frequency noise having shielding characteristics, and enhance the accuracy of measurement of low frequency noise of a sample by blocking the flow of electromagnetic waves in the gap between the chamber and the door.
Claims8
A low frequency noise measuring apparatus with electromagnetic shielding characteristics comprises,
- a first shielding portion formed a first shielding room in which a sample is disposed, and
- a second shielding portion which is formed with a second shielding room in which a low frequency noise measuring device is connected with the sample to analyze a low frequency noise of the sample and adjacent to the first shielding portion,
- wherein the second shield portion comprises
- a second chamber forming the second shield room,
- a second door installed in the second chamber to open and/or close the second shield room, and
- a fixing portion which includes a first fixing body installed in the second chamber and formed with a first insertion opening, a first fixing piece inserted into the first insertion opening to fix the second door to the second chamber, and a handle of which one side is rotatably installed in the second door and the other side is hinge-coupled to the end of the first fixing piece to rotate the first fixing piece at a predetermined angle and fixes the second door to the second chamber while the second door is closed in the second chamber.
