Function Details
Ranging Mode
Ranging Mode
The following ranging modes are available for performing source output or
measurement.
• FIXED (fixed range)
The channel uses the specified range only.
• AUTO (auto range)
The channel automatically uses the range which provides the best resolution for
the source output value or the measurement value. It is possible to specify the
minimum range effective for the auto range operation.
• BEST (best, only for the sweep source channel)
In the linear sweep mode, the channel automatically uses the minimum range
which covers the whole sweep output.
In the log sweep mode, the channel automatically uses the range which provides
the best resolution for each sweep step output.
Setting the Ranging Mode
The following points must be noted when setting the ranging mode.
• The measurement channel does not use ranges higher than the minimum range
which covers the Limit (Compliance) value.
• The pulsed source channel uses the fixed range for measurement. If the ranging
mode other than FIXED is set, the channel automatically uses the minimum
range which covers the Limit (Compliance) value.
• For the source side measurement, the channel uses the present output range.
• To set the ranging mode of the DC (constant) source or measurement channel,
see
“Range parameters” on page 4-12 .
• To set the ranging mode of the sweep source channel, see “Sweep dialog box”
on page 4-29 .
• To set the detail of the auto ranging operation for measurements, see “Ranging
dialog box” on page 4-30 .
