Send the following commands for this example application:
Commands Descriptions
Pseudocode
int scanCount = 10
 Create a variable to hold the scan
count
int channelCount = 6
 Create a variable to hold channel
count
int bufferSize = scanCount *
channelCount
 The number of readings
int lastIndex
 The last scan index in the buffer
after every two seconds
string tmpBuff
 A temporary buffer that store
scanned data every two seconds
DAQ6510
*RST
 Put the instrument in a known
state
:TRAC:POIN bufferSize,
"defbuffer1"

Set the buffer size (not necessary
when using the default buffer, but
added to show command use
case)
:ROUT:SCAN:BUFF "defbuffer1"
 Assign all scanned data to
"defbuffer1"
FUNC 'VOLT:DC', (@101:106)
 Set channels functions to DCV
VOLT:DC:RANG:AUTO ON,
(@101:106)
 Set the channels ranges to auto
VOLT:DC:NPLC 5, (@101:106)
 Set NPLC to 5
VOLT:DC:AZER ON, (@101:106)
 Set autozero function to ON
ROUT:SCAN (@101:106)
 Setup the scan list
ROUT:SCAN:COUN:SCAN 10
 Setup the number of repeated
scans
INIT
 Initiate the scan
Pseudocode
for i = 1; i <= bufferSize;
delay 2000
 Delay two seconds to allow
readings to accumulate
DAQ6510
lastIndex = TRACe:ACTual?
 Query the current buffer index
tmpBuff = "TRACe:DATA? i,
lastIndex, "defbuffer1",
READ
 Query the readings available from
index i to index lastIndex
Pseudocode
printBuffer (tmpBuffer)
 Print readings in temporary buffer
to console
i = lastIndex + 1
end for
DAQ6510
:TRAC:SAVE "/usb1/MyData.csv",
"defbuffer1"
 Save buffer data from defbuffer1
to USB
