Page 213: Program Memory
If frequently used command strings are stored in the program memory, interface/computer activity is minimized. The program memory can be defined by using SCPI commands while B2900 is in the remote mode. See Keysight B2900 series SCPI Command Reference. • Number of programs saved in the memory: 100 •...
Page 214: Channel Grouping
Function Details Channel Grouping Channel Grouping This section applies only to 2-channel models. This function is used to control the channel output timing automatically so that the channel keeps the output while the other channel performs measurement. The grouped channels start the source output in the order of channel number, then start the measurement at the same time, and keep the output until the measurement is completed.
