The binary waveform transfer from Tektronix's VX4240 does not work together with NI's GPIB-VXI/C Slot0. According to Tektronix NI has developed a Code Instrument to circumvent this problem. Where can I get it and how does it work ?
In the past, National Instruments only officially supported a few Code Instruments, which are documented in Appendix B of the GPIB-VXI/C User Manual, but I did not see the VX4240 in the Appendix.
NI officially discontinued support for code instruments on the GPIB-VXI/C about 6 years ago, so you might want to consider moving to a newer VXI controller to access your device. You can find more information on our VXI-MXI-2, VXI-MXI-3, and VXI-1394 remote controller options here.
