Rohde & Schwarz HM020E Loop Antenna 9 kHz – 30 MHz
Description
Rohde & Schwarz HM020E Triple Loop Antenna 9 kHz – 30 MHz allows fully automatic measurement of the magnetic field strength in the X, Y and Z plane as prescribed in CISPR 15 and CISPR 16-1-4.
The DUT is placed on a wooden pedestal in the center of the loops.
The loop construction using a cut coaxial line provides excellent screening against the electric components of the interfering signals so that unambiguous test results are obtained.
Features
- Fully automatic measurements of the magnetic field strength in the X, Y and Z planes of a DUT placed at the antenna center
- Measurement method in line with CISPR/A (Secretariat) 103, 104, 105 and CISPR/F (Central Office) 66, 67
- Remote control via a Rohde & Schwarz EMI receiver
- More sensitive, faster and cheaper than previous methods in line with CISPR Publication 16
- Loop system mobile and foldable into one plane
- Wooden pedestal for 100 kg load available (permitting the loops to be freely moved)
