OUTP[:STAT] ON	Enables the HP E1300A/E1301A "Trig Out" port to
	output pulses.
[ROUT:]CLOS <channel_list>	Close the channels in the channel list.
[ROUT:]CLOS? <channel_list>	Query the state of the channels in the channel list.
[ROUT:]OPEN <channel_list>	Open the channels in the channel list.
[ROUT:]SCAN <channel_list>	Closes the channels in the channel list one at a time.
TRIG:SOUR BUSEXTHOLDIMM	Select the trigger source to advance the scan.
*CLS	Clears all switchbox Status Registers.
*ESE	Enables the Event Status Register.
