•<ch_list> specifies the channels that will control stepper motors. The channels referenced can be on more than one E1538. The channels must be in ascending order. Based on the <mode> parameter, the channels will be arranged into adjacent groups of 2 ("...C2"), or 4 ("...C4") channels. These groups can not be split across SCPs.
The algorithm can send new position values to the first channel in a

Comments • This command is coupled with the SOURce:FM command. If the FM state is enabled then the PULM state is disabled. If the PULM state is enabled then the FM state is disabled. If both the FM and the PULM states are disabled then the PULSe channel is in the single pulse mode.
•If the channels specified are not on a Frequency/Totalize SCP, an error will be generated.
