ACQUISITION MODES
Single Shot: For transient and repetitive signals: 1 GS/s for models 114, 214, 514, 212, 512; 2 GS/s for
models 1021, 1022, 522
Sampling period settable in 1-2-4 sequence.(e.g., PXD512 period: 1 ns/pt, 2 ns/pt, 4 ns/pt, etc.)
Random Interleaved Sampling (RIS): For repetitive signals: up to 50 GS/s
Sequence: Stores multiple events, each of them time stamped (1 ns resolution) in segmented acquisition
memory.
Minimum Segment Length: 256 samples
Maximum Segment Length: 1 million samples
TIMEBASE SYSTEM
Capture Window at Maximum Sample Rate: up to 4 ms
