Example
*RST
:TRACe:MAKE "voltDigBuffer", 10000
:DIG:FUNC "VOLTage"
:SENS:DIG:COUN 100
:READ:DIG? "voltDigBuffer", FORM, DATE, READ
:TRAC:DATA? 95,100, "voltDigBuffer"
Create a buffer named voltDigBuffer. Make a digitize measurement, store it in the buffer
voltDigBuffer, and return the formatted readings, date, and reading buffer elements for the last reading
stored in voltDigBuffer, then return readings 95 to 100.
Example output is:
+04.963 V,09/26/2014,4.962954E+00
4.961211E+00,4.961695E+00,4.961889E+00,4.961985E+00,4.962276E+00,4.962954E+00
