Why does my ESG report errors when I try to download waveforms using a National Instruments GPIB card with certain Signal Studio applications?

If errors reported by the ESG when trying to download waveforms using a NI GPIB card with a Signal Studio application in this scenario include “ -113 undefined header” and “-101 invalid character”, you need to download and install a patch for the Keysight IO Libraries (Suites 14.1 or 14.2 only). The file below includes the patch and instructions for installing the patch.
