Profile: A H Systems, Inc. manufactures EMC test equipments. Our products include antenna kits, dipoles, loops & monopoles antennas, current probes and pre amplifiers. The SAS-510-2 directional log periodic antenna is an ideal solution for radiated emissions and normalized site attenuation. It features a frequency range of 290 MHz to 2000 MHz and is made of lightweight aluminum. Injection current probes are used to inductively couple large RF currents into conductors passing through their aperture. The conductors are signal, control and power circuits of equipment under test for conducted susceptibility or immunity. The active monopole antenna can drive any receiver with 50W input impedance and will perform FCC, MIL-STD and TEMPEST tests. The passive rod is used for transmitting, to perform shielding effectiveness and immunity testing.
