Red Pitaya STEMLab 125-14-4 input 4-Channel, 14 bit
The RF signal acquisition platform Red Pitaya STEMlab 125-14-4 is a 4 inputs digitizer board, derived from the 2-channel STEMlab 125-14 unit. The STEMlab 125-14-4 features 4 input channels for enhanced performance, replacing the previous 2 inputs and 2 output channels. It also includes the Xilinx Zynq 7020 SoC.
- 4 analog input channels at 125 MS/s, 14 bit.
- Enhanced RF input performance (reduced crosstalk, noise, and distortions) compared to 2-channel STEMlab 125-14 version.
- Incorporates Zynq 7020 for increased processing capabilities and additional digital-I/O pins.
- Allows seamless switching between internal and external clocks via a jumper or control signal on the extension connector.
- Optional feature for locking internal ADC clock to an external reference clock through the extension connector (available upon customer request).
- Applications:
Automotive equipment,
multi-channel data acquisition,
base-station IF receivers,
software defined radios,
diversity receivers,
medical imaging,
communications,
non-destructive testing,
test equipment,
cellular base stations. - Can be controlled remotely using LabVIEW, MATLAB, Python, or Scilab.
- Can be reprogrammed according to the user's needs.
- An app marketplace with several free ▸apps is available.
