4.5.3 Source Range
4-23
(2) Restrictions on each source value
Base value: The polarity specified at the time of setting is ignored and becomes the same as
that of the pulse value.
Start value: 0 generates an error for log sweep.
Stop value: 0 generates an error for log sweep.
Step value: The polarity specified at the time of setting is ignored and sweep proceeds from
Start ï‚® Stop.
In linear sweep: (Stop - Start) / Step + 1  5000 generates an error.
In log sweep: If the polarities of start and stop are not identical, an er-
ror is generated.
When |Start|  |Stop|, an error is generated.
If an error is generated, operation is not possible.
4.5.3 Source Range
(1) Source ranging
• The source values (pulse values) of the DC mode and pulse source mode are output in the dis-
played range.
• Base value, bias value, start value and stop value ranges are decided by the fixed/auto range as
shown in the following table with no relation to the set values or displayed values.
