The Ranatec RI 1801 is a ultra-linear digitizer for demanding signal analysis. It features 100 dB spurious free dynamic range and 550 MHz input bandwidth. This is accomplished by using an ultra-linear ADC that works up to 160 Msps at 16-bit resolution. The 32 MB on-board memory enables storage of 16 million samples, which corresponds to 0.1 seconds at full speed.

Hardware architecture

All signal processing is done in an FPGA. This enables users to always be up-to-date with the latest available firmware. For advanced users, there is also a possibility to download their own, proprietary, realtime signal processing algorithms. This could be invaluable for cutting production test-time. Your PASS/FAIL decisions may be made locally in the PXI module.

Triggering, Clocking and Synchronization

• Full PXI triggering support, including trigger bus,
local bus and star trigger
• Internal 160 MHz or external 1-160 MHz sample
clock (software selectable)
• Phase lock to PXI 10 MHz reference
• Pretrig and posttrig acquisition
• The flexible hardware architecture enables
user-defined triggering events
