CONFigure[<
chan
>]
The CONFigure subsystem provides a fast way to place the HP E1429 into a known
state, ready to take measurements. An INITiate;FETCh? is then all that is necessary
to take a measurement after the CONFigure command has been executed. If
desired, CONFigure may be used to quickly get to a known state, from which other
states such as TRIGger:STARt:SOURce or TRIGger:STARt:TIMer can be "fine
tuned" to desired values before the INITiate;FETCh? sequence is executed.

CONFigure[<chan>]:ARRay[:VOLTage][:DC] (<size>)[,<expected
value>[,<resolution>]] [,(@<input port>)] will configure for taking <size> number
of readings on the specified channel and <input port>. The <expected value> and
<resolution> parameters are used to set SENSe:VOLTage:RANGe to an appropriate
setting for making the measurement on the specified input port and channel. If no
expected value is given, the 1V range (1.0235 V peak) is used. If a resolution is
specified, it is checked for correctness against what is possible with the expected
value range, and if too fine for the given expected value, error -231,"Data
questionable;CONF or MEAS unable to attain resolution specified" will occur.
Each channel consists of two ports; one port is single ended, and the other is
differential. The two ports on channel 1 have odd numbers: port 1 is the single
ended input and port 3 is the differential input. On channel 2, the single ended input
is port 2 and the differential input is port 4.
The expected value parameter specified should be the maximum expected
measurement value. The voltage range is set according to the expected value
supplied. If the expected value is greater than 98% of a given range, the next higher
range is automatically chosen. The table under the "Settings" heading gives the
crossover points for range changes.
