LXinstruments GmbH
The in-vehicle test set was developed to successively measure several active RF amplifiers installed in the vehicle as well as different antenna structures. It offers the possibility to connect 12 DUTs. The DUTs can be connected to an external spectrum analyser via a 1 to 12 RF multiplexer. Each DUT can be individually switched and supplied with an adjustable voltage via a bias-tee integrated in the system. The individual bias voltages and currents are recorded by the IVTS and can be called up on an interactive control panel or via Ethernet and SCPI commands. The complete system can be powered by rechargeable battery and can be operated either via Ethernet, fibre optics or WLAN.

Pulse Characterization Sensors provide the ability to see and measure the temporal characteristics of pulsed and CW laser beams. Ophir Fast Photodiode Detectors are designed to convert optical signals into electrical signals which are then measured with third-party instrumentation such as oscilloscopes and spectrum analyzers. Accessories are available to connect to IS6 integrating spheres or fiber optic cables. Attenuating filter accessories are also available to increase their dynamic range. Different models offer silicon, UV enhanced silicon and InGaAs PIN photodiodes, covering a combined spectral range of 193 nm to 1700 nm. Rise times range from 25 picoseconds to 3 nanoseconds. The fast rise times are achieved by an internal reverse bias voltage circuit. Power is supplied by internal batteries and/or an external power supply depending on the model. Detectors should be connected to a 50Ω impedance in order to maintain their nominal rise times. They can be connected to higher impedance loads, but this will result in a significant increase in the rise time. If higher output voltage is required, it is recommended to connect the detector to a trans-impedance amplifier with an Input impedance of 50Ω
