HEIM DATaRec® 4 series Technical Specifications DIC24 DC Additional Infos Synchronicity of samples Environmental specifications In a Link chain configuration with several analog modules the sample synchronicity of all modules depends on the sampling frequencies of each module. For sample synchronicity the module sampling frequency must be a multiplier of 2 to the power of n (Fs x 2n; n = wholenumbered) of each other module sampling frequency. Example: One module sampling frequency (Fs) = 4kHz. Sampling frequency of all other modules must be one of the following: 4kHz x 20 (= 4kHz), 4kHz x 21 (= 8kHz), 4kHz x 22 (= 16kHz), 4kHz x 23 (= 32kHz), 4kHz x 24 (= 64kHz), and so on; or 4kHz x 2-1 (= 2kHz), 4kHz x 2-2 (= 1kHz), 4kHz x 2-3 (= 0.5kHz), 4kHz x 2-4 (= 0.25kHz), and so on.
