The transfer could take up to 10 seconds. Normally it is 6 or 7 seconds, however this will vary depending on the performance of the PC and the GP-IB board. On the DL1540C Digital Oscilloscope, this may take longer than 10 s, because the screen image data contains color information. Assure that the time-out setting for the PC being used is set long enough to accommodate the required transfer time.
