PCIe 14 Bit High Speed Digitizer - 500 MS/s on 4 Channels
M4I.4451-X8
The 6 models of the M4i.44xx-x8 Express series are designed for the fast and high quality data acquisition. Each of the input channels has its own A/D converter and its own programmable input amplifier. This allows the recording of signals simultaneously on all channels with 14 bit or 16 bit resolution without any phase delay between them. The card uses only one A/D converter even when running with 500 MS/s, guaranteeing best signal quality without any interleaving technology. The extremely large on-board memory allows long time recording even with the highest sampling rates.

RF Frontends
Becker Nachrichtentechnik GmbH
Software-Defined Radio (SDR) is an attractive approach for mobile communication architectures in the development and evaluation phase for a rapid prototyping on a flexible platform. SDRs support a wide frequency range. However, for practical use in the field the HF properties are insufficient. The transmit power is limited to a 2-digit mW value. Dedicated filters are required for an effective suppression of out-of-band signals and to improve the noise figure of the receiver chain. Extending SDRs with application-specific RF-frontends achieves optimal RF performance in the field.

Transformer Rectifier Assemblies
Transformer rectifier assemblies are very useful in OEM applications when unregulated DC output is required. Input power can be single-phase or three phases. With single-phase input power, the output ripple is 50%. With three-phase input power, the output ripple is 5%. A 5% output ripple is a clear advantage. Hence, transformer rectifier assemblies with three-phase input power are more popular. Circuit breakers, fuses, voltmeters, and ammeters can be added per customer requirements. The assemblies can be an open frame or inside an indoor enclosure.
