Phase Locked Oscillators
Phase locked oscillators (PLO) utilize state-of-the-art planar circuits, three-terminal devices and dielectric resonator technology to generate high-quality microwave signals at lower frequencies. Frequency multipliers, amplifiers and filters are used to extend the low frequencies for higher frequency requirements. The standard offering covers the frequency range of 2 to 110 GHz and provides both internal and external reference options. The frequency stability and phase noise are dependent on the oscillator reference type.

Pyroelectric and Thermal Testing
The optional Chamber Task measures the Pulse Polarization response and Small Signal Capacitance of a Pyroelectric material that is being heated and/or cooled within a thermal chamber, on a hot chuck or in a furnace. From these measurements the Spontaneous Polarization Pr(q) and the Dielectric Constant er(q) are computed. These are then combined to determine the Electrical Displacement D(q) as a function of the temperature q.

Loss Tangent M in Dielectric Oil
TAND220A
The measuring instrument type TAND220A complies with the international standard IEC 61620. The instrument is based on the so-called "low-amplitude, low-frequency alternating current square wave method" and allows accurate measurements of conductivity and relative permittivity. Conductivity measurement in the range of 0.01 pS/m to 20,000 pS/m allows the use of this instrument for quality control of high resistivity liquids even at room temperature. The TAND220A works with a low test voltage and also with a low test current so that it does not represent a danger for the operators.

Insulating Oil Testers
The main functions of electrical insulating oils are heat dissipation and reliable insulation of energised parts of electrical installations. During the normal operation, moisture and other impurities penetrate into insulating oils, leading to a deterioration of their dielectric properties. This in turn may result in catastrophic failures of critical electrical equipment.

Dielectric Withstanding Voltage Test
The dielectric withstanding voltage test (also called high-potential, over-potential voltage-breakdown, or dielectric-strength test) consists of the application of a voltage significantly higher than rated voltage for a specific time, between mutually insulated portions of a component part or between insulated portions and ground. This is used to prove that the component part can operate safely at its rated voltage and withstand momentary over-potentials due to switching, surges, and other similar phenomena.

Full Band Phase Shifters
STP-18-10-M2
Full band phase shifters are micrometer-driven, waveguide-based phase shifters. The configuration of the micrometer-driven phase shifters is similar to that of level setting attenuators, where the phase shifting is caused by an E-plane dielectric insert in the rectangular waveguide. The amount of phase shifting is directly dependent on the volume of the insert. The VSWR and the insertion loss of these phase shifters are dependent on the frequency. The below standard offering covers the frequency range of 18 to 110 GHz and a phase shifting range of 180 degrees. These micrometer-driven phase shifters are typically used to introduce a certain amount of phase shifting when the absolute number is not a focus.
