Set Trigger Level

 

 

Sets the level against which the testing of channel readings should

be performed where 

 is the channel number such that 

 <

 < 

,

 

where max = 128 for ChartScan/1400.

 

 is the level against which the readings are tested to

determine if the level has been exceeded.

 

 is the hysteresis level.

 

 

 

 

Query the the current level settings

 

 

 

 

 

 

Set SRQ Mask

 

 

Use the IEEE 488 Service Request (SRQ) mechanism to inform

the IEEE 488 bus controller of certain conditions, where 

is in the form of the number 

 such that 

 < 

 < 

 is

summed from the following conditions:

 

 - Power-on default mask value.

 

 - SRQ On Alarm.

 

 - SRQ On Trigger Event.

 

 - SRQ On Ready.

 

 - SRQ On Scan Available.

 

 - SRQ On Message Available (MAV).

 

 - SRQ On Event Detected.

 

 - SRQ On Buffer Overrun.

 

 

 

 

Query the SRQ mask.

 

 

 

 

 

 

Set Measuring Mode

 

 

Specify measuring mode.  Valid options for 

 are: 

 - Line

cycle integration / high-speed multi-channel mode, and 

 -

Single channel high-speed burst mode.

 

 

 

 

 

 

Set Event Mask

 

 

Directly sets the Event Status Enable Register (ESE) where 

is in the form of the number 

 such that 

 < 

 < 

 is

summed from the following conditions:

 

 - Clear event mask

 

 - Acquisition complete

 

 - Stop Event

 

 - Query Error

 

 - Device Dependent Error

 

 - Execution Error

 

 - Command Error

 

 - Buffer 75% Full

 

 - Power On

 

 

 

 

Query the Event mask.

 

 

 

 

 

 

Set Digital Outputs

 

 

Set any of the 32 digital outputs (separated into four 8-bit banks)

to a specified setting, where 

 (

 = 

, 

, 

, 

) is an

argument in the form of the number 

 such that 

 < 

< 

 when converted to binary format represents the desired

settings for the 8-bit bank.

 

 

 

 

Query current state of digital output.

 

 

 

 

 

 

Program Trigger Times

 

 

Set the trigger start and/or stop times for an acquisition configured

for start and/or stop on absolute time, where 

 and 

are in the standard time/date stamp format: 

 

where 

 is hours, 

 is minutes, 

 is seconds,

 is tenths of a second, 

 is month, 

 is day, and 

 is year.

 

 

 

 

Query current start and stop times.

 

 

 

 

 

 

Query

 

 

Query present configuration or mode of command preceding the 

 

 

 

 

 

 

Set Query Terminator

 

 

Set the query terminators with the following parameters: 

 is

the response terminator, 

 is the channel terminator, 

is the terminator which follows each scan output, and 

 is

the terminator which follows each trigger block output.

 

 determines whether or not a separator character should be

used.  Valid options for 

 are: 

 - Place no separators in

returned buffered scan data when it is read, and 

 - Place a

separator whose value is determined by the current Set User
Terminator (

) command setting into the returned buffer data

when it is read.

 

 

 

 

Query current terminator settings.

 

 

 

 

 

 

Query Card Data

 

 

Read back card ID and calibration information from the card

previously selected by the Select Card (

) command.
