Dual-ridge Horn Antenna 1 to 18 GHz
EH118
-
EH118, a dual-ridge horn antenna that will operate from 1 to 18 GHz. This antenna has a balanced, smooth antenna factor curve that extends all the way to 18 GHz, a reduction of higher order modes on the aperture, and low return loss (SVSWR). The EH118 is applicable for commercial, military and automotive test standards and will include applicable calibrations. The EMC dual-ridge horn antenna offers these key features: single linear polarization, smooth/balanced gain with frequency, low return loss /VSWR, and ultrawide bandwidth (18:1).

100base-T1 Ethernet (BroadR-Reach®) Logging Expansion With Low Latency
PT-15B
-
The PT-15B expands the PM-200 data logger from the Power Family by adding twelve 100base-T1 interfaces. Ethernet traffic is looped through the device with constantly low latency irrespective of the frame length. This means that the time synchronization protocols of the logged Ethernet interfaces are not affected. 100base-T1 packets are time stamped, filtered and sent to the PM-200 data logger via a 1000base-T interface.

Biconic Logarithmic Periodic Antennas
Stacked LPDA
-
The stacked Logarithmic Periodic Dipole Antenna consists of two ordinary Log.-Per. structures. The excellent characteristics (flat gain over a large bandwidth, low SWR) of the ordinary Log.-Per. designs could be maintained using the stacked LP design. The stacked design helps to focus the directional pattern of the H-plane somewhat, resulting in a typical gain improvement of ca. 2-3 dB compared to an ordinary LPDA. This is especially important for immunity testing, where a maximum fieldstrength and a good field uniformity is required. The beamwidth in the E-plane and the H-plane are nearly identical, providing an optimised illumination of the EuT with minimised ground reflection influence. Further the STLP 9128 C has an excellent cross-polar rejection.
