incomplete physlog data, VD13A, BOLD #62

Closed chaigner closed 10 years ago

chaigner commented 10 years ago

Dear CMRR-MB team,

we started to use R10c and upgraded to R011a on our Skyra (VD13A SP4). We are interested in the integrated physlog feature (pulse) of the BOLD variance. Unfortunately we face a systematic problem concerning the trigger based pulse logging. If we perform more than 310 measurements the logfile stops after the 319th trigger (9 dummys + 310 measurements?) using the stop code "5003" but without "ACQ FINISHED". Further pulselog-data is missing. After the upgrade to R011a a smaller number (<310) of measurements are logged successfully (eg 200 measurements = 209 trigger). Any help concerning our problem is highly appreciated.

Best regards, C. Aigner

Dear CMRR-MB team,

we solved the problem concerning incomplete pulse log files that I described in the earlier posting. The physlog data measurment/export is somehow connected to the ECG signal and if there is no ECG signal, as in our earlier measurments, the acquisition stops after a constant time. Connecting and using the ECG together with the pulse oximeter solves this problem and leads to a complete set of measurements.

Best regards, C. Aigner
