Schwarzbeck Mess Elektronik
Biconical Antennas have dipole like characteristics (e.g. circular directional pattern in the H-plane,"8"-shaped in the E-plane, fixed phase center, comparable gain), with an enormous wide bandwidth achieved by the double cone elements. One of the earliest and worldwide most popular biconical antenna designs is the BBA 9106 with balun VHA 9103 B. During the last years a growing need for expanded frequency ranges arised, which led to the design of biconical antennas reaching down to frequencies of 20 MHz and up to 18 GHz and above. A further increase of bandwidth was achieved with qualified 4:1 baluns, providing a typical gain increase of approx. 6 dB at the lower frequency range. The biconical elements can be mounted and dismounted within a few seconds providing perfect contact repeatability thanks to special clamping fixtures. A small wrench made of insulating material is supplied with the balun, it is tied to the balun head and thus always available whenever needed. Biconical antennas can be used for many applications, in which half-wave dipoles have been used traditionally. An enormous reduction of measurement time can be achieved, because the time consuming tuning of the antenna elements to the half wavelength is not needed, an important condition for sweeped broadband measurements. In typical dipole applications several discrete frequencies are measured, in contrast the biconical antenna allows continuous sweeps, where site anomalies are discovered much easier.

RF1 set -
Langer EMV-Technik GmbH
The RF1 near field probe set consists of 4 passive near field probes for making measurements in the development phase of E-field and magnetic field in the ranges of 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF1 set allow for measurements close to the electronic assemblies, e.g. on single IC pins, conducting paths, components and their connectors in order to localize interference sources. Field orientation and field distribution on an electronic assembly can be detected through a trained special use of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance.

PT-1 -
International Electro-Magnetics, Inc.
The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding. The induced signal is low level and completely safe for the operator. By comparing the test signal phase of the coil under the test output, the relative polarity is indicated by the Red/Green LED. The tester operates by inducing a signal voltage in the coil under test by means of a magnetic flux field. The field is generated by a coil located in the probe base. The coil configuration is designed to provide optimum field distribution. We have also applied this basic circuit to a 5-channel scanning unit.
