ENOB as a Measure of Digitizer Performance

Most engineers and scientists focus on sample rate and resolution when selecting high speed digitizer products. Those "banner specs" will usually narrow the pool of candidates in the final selection. To really understand the true overall performance, the best specification to use is ENOB, or Effective Number of Bits. The use of ENOB allows one to evaluate the entire performance of the product under consideration. It includes errors and non-linearity in the data converter chip, the front end analog amplifier, sample clock jitter, and interleave function, if used to extend the sample rate.

Graph of 12-Bit Digitizer ENOB Performance: CompuScope EON

To be used effectively in comparing products, one should look at ENOB versus frequency - ENOB is usually much better at lower frequencies.

2 GS/s 12-Bit Digitizer Promotion

GaGe is now offering a promotion on its 12-bit high-performance EON digitizer. The promotion includes the 12-bit EON Digitizer board with deep memory option, choice of application software, and PCI Express interface module at a special low price. This promotion is especially attractive for portable laptop based measurements, or small form factor PC based solutions, which cannot host a full size card slot.
