EM-6878 | 9 kHz – 30 MHz
The EM-6878 Loop Antenna performs magnetic field measurements from 9 kHz to 30 MHz. A ten position rotary switch is used to switch in the appropriate matching network for the frequency selected. The antenna is calibrated for and can be used with any 50-ohm receiver/analyzer system.
The bottom of the base contains a 5/8-11 threaded receptacle for mounting to the Model EM-6136-1 Tripod. Optional inserts can be purchased to reduce to a standard ¼ -20 thread.
The EM-6878 uses passive circuitry to transform magnetic field components between 9 kHz and 30 MHz to a voltage output for use by any 50-ohm input receiving system.
The EM-6878 is particularly suited for application in military EMI specification compliance testing such as is outlined in the various revisions of MIL-STD-461.
