  • RF Adapter Module For FlexRIO

    NI

    RF Adapter Modules for FlexRIO feature frequency coverage from 200 MHz to 4.4 GHz, with up to 200 MHz instantaneous bandwidth. When paired with a PXI FPGA Module for FlexRIO or the Controller for FlexRIO, you can program the FPGA using LabVIEW to implement custom signal processing, including modulation and demodulation, channel emulation, spectral analysis, and even closed-loop control. These modules are all based on a direct conversion architecture and feature an onboard local-oscillator which can be shared with adjacent modules for synchronization. RF adapter modules also provide digital I/O capability for interfacing with external hardware.

  • High Voltage Power Supplies

    Guth GmbH

    The mains voltage (230V / 3 x 400V) is transformed, rectified and filtered by the HN series. The direct current output voltage is tuned by a variable transformer or regulated by a thyristor controller. With the HS and HV series the rectified mains voltage is supplied to a frequency converter, which produces a mid-frequency square wave voltage. This transformed, rectified and filtered alternating current produces the desired voltage as output, which is regulated by means of frequency variation or pulse width modulation. The equipment in the HV series supply, in addition to the high voltage output, up to 3 auxiliary outputs which can be used to supply e.g. heating, grid voltage or surge voltage.
