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.

L-Band Separate Raman Fiber Amplifier
RFA6000
-
Hangzhou Huatai Optic Tech. Co., Ltd.
1. Erbium-doped Fiber Amplifier, due to the multiple cascades and the accumulation of noise caused by spontaneous emission, will reduce the system CNR greatly and thus it will limit the transmission capacity and distance of the system. Raman Fiber Amplifier (RFA) is a newly designed fiber amplifier based on Stimulated Raman Scattering (SRS) effect. It is considered as the core technology of new generation DWDM fiber over-long communication. Compared with Erbium-Doped Fiber Amplifier, Raman amplifier has the advantage of low Noise Figure (NF), wider gain bandwidth, flexible gain spectral region and stable temperature. It is the only device that can operate in 1300~1600 nm.

Transformer Ratio Meters
Handheld Turns Ratio & Winding Resistance Tester TWR-H
-
TWR-H is a handheld, battery operated, fully automatic test set specially designed for turns ratio, phase shift, excitation current and winding resistance measurements of transformers. It can also perform demagnetization of these transformers. Transformer turns ratio is determined by applying AC voltage across high voltage winding, accurately measuring AC voltage across the corresponding unloaded transformer winding, and then displaying the ratio of these voltages. User can enter a transformer’s nameplate voltages, so that turns ratio deviation can be calculated. This feature eliminates any error otherwise caused by an operator’s manual calculation. TWR-H compares measured turns ratio with the nameplate ratio and prints out the % of error for each test. Transformer winding resistance is determined by injecting DC current through a winding, accurately measuring DC voltage across the winding, and then calculating resistance as the ratio of voltage and current. The device generates true DC ripple-free currents. Both the injection of the current and the discharge of energy from transformer magnetic circuit are automatically regulated.

Magnetic Field and Permeability Measurement
MAGNETOSCOP® 1.070
-
Foerster Instruments, Incorporated
The MAGNETOSCOP 1.070 is a portable magnetometer system with microprocessor and probes for measuring the magnetic flux density as an absolute or differential value (gradient). It has a USB port for simple data transfer and an SD card for saving measurement data and parameters. The measuring system also facilitates the recognition and saving of peak values and the adjustment of thresholds for limit values. The unit can be used for series and individual measurements. The data can be easily analyzed and documented with the PC software included in the scope of delivery. The MAGNETOSCOP 1.070 thus facilitates the portable and fast measurement of the relative permeability within the scope of the quality control of stainless steel and low-permeable (non-magnetic) alloys as well as the localization of ferrite enclosures. Changes in material (sulfidation, degradation of lamination, structural changes) can also be proven thanks to permeability comparative measurements.
