Key product information and technical features.
Conventional mode provides 8-bit acquisition. Flexible-resolution mode trades sampling rate and bandwidth for higher effective resolution, with anti-alias filtering.
Random-interleaved sampling reaches an effective 1 GS/s for repetitive signals; it is not a 1 GS/s real-time acquisition mode.

Product-specific answers based on available technical information.
No. Conventional acquisition is 8-bit. The 21-bit effective-resolution setting operates at 10 kS/s with 4 kHz bandwidth.
It is an effective random-interleaved sampling rate for repetitive signals. Maximum real-time sampling is 100 MS/s.
The catalog record does not identify it. NI documents 4 MB and 16 MB options; confirm the installed option separately.
