Spectrum Instrumentation has released six new Arbitrary Waveform Generators (AWGs) that are optimized for signal quality, size and cost. The new “65” series AWGs offer the latest 16-bit Digital-Analog-Converters, a fast PCIe x4 interface with up to 700 MByte/s streaming speed and a card length of only 168 mm to fit into nearly every PC.…
Spectrum Instrumentation Digitizers and AWG used for Atmospheric research with LIDAR at Leibniz Institute
Atmospheric research uses pulsed laser beams to measure temperature and wind speed along the beams by measuring the Doppler shifted and backscattered light at 100 km height in the atmosphere. The returning light signals are very weak and can be blocked by sunlight, but The Leibniz Institute for Atmospheric Physics (IAP) has solved this problem: they developed…
Spectrum Boxcar Function Gives Clear Improved Signal
The Boxcar averaging function smooths out high frequency noise to give a clear signal. It is most useful in situations where signals have been oversampled and it can be used to increase vertical resolution, lower noise and improve dynamic characteristics such as signal-to-noise ratio (SNR) and spurious free dynamic range (SFDR). It uses a mathematical…
