Example
TRACe:MAKE "testData", 100
SENSe:COUNt 5
MEASure:CURRent:DC? "testData", READ, REL
TRACe:SAVE "/usb1/myData5.csv", "testData"
TRACe:CLEAr
MEASure:CURRent:DC?
TRACe:SAVE:APPend "/usb1/myData5.csv", "defbuffer1"
MEASure:CURRent:DC? "testData"
TRACe:SAVE:APPend "/usb1/myData5.csv", "testData", RAW, 6, 10
Create a buffer called testData.
Make 5 readings and return the fifth point, which will contain the reading, relative timestamp, and source value.
Store the buffer data in the myData5.csv file.
Clear defbuffer1.
Make 5 readings, store them in defbuffer1, and return the fifth reading.
Append all the readings stored in defbuffer1 to the myData5.csv file.
Take 5 more readings, store them in testData, and return the fifth reading.
Append all the readings stored in positions 6 through 10 testData to the myData5.csv file using raw
timestamps.
