API Commands Appendix A

	Command	Syntax		Description
L	Set Trigger Level	Lchan,	Sets the level against which the testing of channel readings should
		level,	be performed where chan is the channel number such that 1 <
		hyst	chan < max,
			where max = 128 for ChartScan/1400.
			level is the level against which the readings are tested to
			determine if the level has been exceeded.
			hyst is the hysteresis level.
		L?	Query the the current level settings
M	Set SRQ Mask	Mmask	Use the IEEE 488 Service Request (SRQ) mechanism to inform
			the IEEE 488 bus controller of certain conditions, where mask
			is in the form of the number nnn such that 000 < nnn < 255 is
			summed from the following conditions:
			000	- Power-on default mask value.
			001	- SRQ On Alarm.
			002	- SRQ On Trigger Event.
			004	- SRQ On Ready.
			008	- SRQ On Scan Available.
			016	- SRQ On Message Available (MAV).
			032	- SRQ On Event Detected.
			128	- SRQ On Buffer Overrun.
		M?	Query the SRQ mask.

M#

Set Measuring Mode

M#mode

Specify measuring mode. Valid options for mode are: 0 - Line cycle integration / high-speed multi-channel mode, and 1 - Single channel high-speed burst mode.

N	Set Event Mask	Nmask	Directly sets the Event Status Enable Register (ESE) where mask
			is in the form of the number nnn such that 000 < nnn < 255 is
			summed from the following conditions:
			000	- Clear event mask
			001	- Acquisition complete
			002	- Stop Event
			004	- Query Error
			008	- Device Dependent Error
			016	- Execution Error
			032	- Command Error
			064	- Buffer 75% Full
			128	- Power On
		N?	Query the Event mask.
O	Set Digital Outputs	Obank1,	Set any of the 32 digital outputs (separated into four 8-bit banks)
		bank2,	to a specified setting, where bankn (n = 1, 2, 3, 4) is an
		bank3,	argument in the form of the number nnn such that 000 < nnn
		bank4	< 255 when converted to binary format represents the desired
			settings for the 8-bit bank.
		O?	Query current state of digital output.
P	Program Trigger Times	Pstart,	Set the trigger start and/or stop times for an acquisition configured
		stop	for start and/or stop on absolute time, where start and stop
			are in the standard time/date stamp format: HH:MM:SS:T,
			mm/dd/yy where H is hours, MM is minutes, SS is seconds,
			T is tenths of a second, mm is month, dd is day, and yy is year.
		P?	Query current start and stop times.

?

Query

?

Query present configuration or mode of command preceding the ?

Q	Set Query Terminator	Qresp,	Set the query terminators with the following parameters: resp is
		hll,	the response terminator, hll is the channel terminator, scan
		scan,	is the terminator which follows each scan output, and block is
		block,	the terminator which follows each trigger block output.
		sep	sep determines whether or not a separator character should be
			used. Valid options for sep are: 0 - Place no separators in
			returned buffered scan data when it is read, and 1 - Place a
			separator whose value is determined by the current Set User
			Terminator (V) command setting into the returned buffer data
			when it is read.
		Q?	Query current terminator settings.

QC?
