Data can be transferred to and from the 7 available display trace types. Use the commands in the MMEMory subsystem to store and recall traces from the instrument memory. The response begins with an ASCII header. The header specifies the number of following bytes. It looks like #AX, where A is the number of digits in X and X is the number of bytes that follow the header. Parameters are returned in comma-delimited ASCII format. Each parameter is returned as “NAME=VALUE[ UNITS],” Valid parameter names are shown in Chpater 2.
Use the commands in the MMEMory subsystem to store and recall traces from the instrument memory. Except for CONStln there is only one value per data point. If max hold is set to ON for SPECtrum and EVM vs. Sub Carrier then the max hold value is returned. For CONStln, each data point is represented by 3 values 4 bytes each: IData (no units), QData (no units), and the constellation type (no units). For SPECtrum and PVTime unit is in dBm. For Spectral Flatness unit is in dB. For EVM vs Sub Carrier and EVM vs Symbol unit is in percent. Note that the instrument must be set in the selected view. Use the CONFigure command to set the unit to the selected view.
