Frequently Asked Questions
What is a 4-channel digitizer card used for?
A 4-channel digitizer card like the PCIE-1840L is used for simultaneous acquisition of multiple analog signals in test, measurement, and industrial automation applications. The four channels enable parallel data capture from different signal sources, making it ideal for complex signal analysis and multi-sensor monitoring.
What does 80 MS/s sampling rate mean?
80 MS/s (megasamples per second) indicates the digitizer card can capture 80 million samples per second per channel. This high sampling rate ensures accurate reproduction of fast-changing signals and is essential for capturing high-frequency components in signal acquisition applications.
How much data can the PCIE-1840L store?
The PCIE-1840L features up to 2 GB of onboard sample memory, providing substantial buffer capacity for extended data acquisition sessions. This large memory capacity allows continuous high-speed data capture without frequent data transfers to the host system.
What is ENOB and why does 11.4 bits matter?
ENOB (Effective Number of Bits) represents the actual resolution quality of the digitizer after accounting for noise and distortion. The PCIE-1840L's true ENOB of 11.4 bits ensures reliable, accurate signal digitization with minimal noise, critical for precision measurement and data acquisition applications.
