Table 3–6: Meaning of Returned String
Returned Meaning
AutoRange OFF The state of the autorange enable (ON | OFF | ONCE)
AutoZero OFF The state of the autozero enable (ON | OFF)
Aperture=0.00166667 The aperture setting
RPSec=600 The number of readings per second corresponding to the
aperture
NPLC=0.1 The number of power line cycles corresponding to the aperture
LFR=60 The line frequency rejection value
FETCh? Subsystem
The FETCh? subsystem is the lowest level of the measurement subsystem. It
retrieves the measurement data acquired through higher level commands. The
optional parameters selectively control which of the acquired value(s) the
measurement subsystem returns. If the optional parameters are not specified, the
command returns the amount of data specified by the <Array Size> field of the
higher level commands.
For example, if the subsystem acquires thirty measurements, issuing a “FETCh?”
returns the thirty values. Issuing a “FETCh? 10” would return the first 10 values
acquired. Issuing a “FETCh? 10,21” would return 10 data values, beginning at
offset 21 of the array (offset 1 = the first data value). Issuing a “FETCh? 5,1,2”
would return five data values, beginning with the first acquired value, and
stepping two locations for each value returned (values one, three, five, seven, and
nine). If the parameters specify an index outside the number of measurements
acquired, an error will be generated.
A subsequent FETCh? will return the same data if a new measurement has not
been INITiated.
