FETCh:ARRay:CURRent[:DC]? [<start_index>, <points>]
FETCh:ARRay:VOLTage[:DC]? [<start_index>, <points>]
FETCh:ARRay:POWer[:DC]?
Returns the instantaneous measurement. Values returned are either in amperes, volts, or watts.
Optional parameters specify a subset starting at <startindex> and of length <points>.
The return format depends on the settings of the FORMat:BORDer and FORMat[:DATA] commands.
When the data format is set to ASCII, returned values are comma separated. When the data format is
set to REAL, data is returned as single precision floating point values in definite length arbitrary block
response format.
Parameter
[<startindex>] the start index
[<points>] the number of points
Returns the measured current array FETC:ARR:CURR?
FETCh:ELOG? <maxrecords>
Returns the most recent external datalog records. Data must be read from the buffer periodically to
avoid the buffer overflowing. Whenever data is read using FETCh:ELOG? then that buffer space is
made available in the instrument for storing more acquired data.
Maxrecords is the maximum number of records of datalog data that the controller will return.
The return format depends on the settings of the FORMat:BORDer and FORMat[:DATA] commands.
When the data format is set to ASCII, returned values are comma separated. When the data format is
set to REAL, data is returned as single precision floating point values in definite length arbitrary block
response format.
Parameter
[<maxrecords>] the number of records returned (1 to
16,384)
Returns 100 data records FETC:ELOG? 100
204
Typical Return
<value> [,<value>]
or <Block>
Typical Return
