Open Ephys analog and digital signal chain latencies. Oscilloscope delays were measures between an input TTL pulse and the generated response TTL. (A) Serially performed latency measurements (top) and histogram of latency values (bottom) corresponding to the setup in Supplementary Figure S3A. (B) Same measurements for the setup in Supplementary Figures S3B. (C) Same measurements for the setup in Supplementary Figures S3C. (D) Same measurements for the setup in Supplementary Figure S3D. No differences between digital (A,B) and analog (C) signal processing were found. ZMQInterface (B–D) did not introduce long delays.
