:ROUT:MEM:READ:STAT 9,ON
Enable measurement during scan; during a scan the
measurement is initiated automatically. This does
not apply when a memory pattern is recalled as
shown below. In the latter case, the reading must be
initiated explicitly as also shown below.
Perform the entire inflator test sequence by scanning through the memory locations:
:ROUT:SCAN
(@M1,M2,M3,M4,M5,M6,M7,M8,M9)
Set up scan list; specify memory locations to be
scanned. They will be scanned in the order in which
they are listed.
:TRIG:SOUR IMM
Set Trigger Source to Immediate; trigger event
detection is satisfied immediately.
:TRIG:COUN 1
Set Trigger Count to 1.
:SAMP:COUN 9
Set Sample Count to 9 to match number of memory
locations being scanned. These Trigger and Sample
Count values cause memory locations to be scanned
one time.
:TRAC:CLE
Clear the nonvolatile data buffer.
:TRAC:POIN 9
Set buffer size to 9 readings.
:TRAC:FEED CALC1
Store results of math calculations in data buffer; if
math function is not enabled, then raw measured
data is stored.
:TRAC:FEED:CONT NEXT
Arm or enable the buffer.
:ROUT:SCAN:LSEL INT
Arm or enable the scan.
:INIT
Initiate the scan; one by one the memory locations
will be recalled in the order identified in the scan list.
The instrument will be configured per the memory
location setups and readings will be taken and stored
in the data buffer.
Wait for scan to complete.
Use program delay or instrument feature such as
*OPC? or Status Registers and SRQ.
:ROUT:SCAN:LSEL NONE
Disable the scan.
:TRAC:FEED:CONT NEVER
Disable the buffer.
:ROUT:OPEN:ALL
Open all relays.
