Example
TRACe:MAKE "testData", 100
SENSe:COUNt 5
MEASure:CURRent:DC? "testData", READ, REL, SOUR
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.

Usage
:TRACe:STATistics:AVERage?
:TRACe:STATistics:AVERage? "<bufferName>"
<bufferName>
A string that indicates the reading buffer; the default buffers (
defbuffer1
or
defbuffer2
) or the name of a user-defined buffer; if no buffer is specified,
defbuffer1
is used
Details
This command returns the average reading calculated from all the readings in the specified reading
buffer.
When the reading buffer is configured to fill continuously and overwrite old data with new data, the
buffer statistics include the data that was overwritten. To get statistics that do not include data that
has been overwritten, define a large buffer size that will accommodate the number of readings you
will make.
