When loading a user file through the software's Data dialog box, the MXG/EXG requires an ASCII text file consisting of 1s and 0s. When using SCPI commands, all instruments require a binary data file.

ACK All	This choice configures 1,280 subframes (if TTI=2ms) or 1,280 frames (if TTI=10ms) for a simulated ACK only response.
Custom Pattern	Sets the HARQ ACK/NACK data pattern to Custom Pattern. The value of this command is a string which is represented ‘0’ or ‘1’. The maximum data length is 18,000 patterns.
User File	This variable represents an ACK pattern file stored in instrument memory.
External	Sets the HARQ ACK/NACK data pattern to External. This choice specifies an external HARQ ACK/NACK pattern.
