H
XGONOGO cursor - provides GO^NOGO testing to determine whether
a curve passes between two endpoints of the cursor bar placed along
the X axis. This is useful when a device with certain characteristics must
be selected from devices of widely varying characteristics.
H
YGONOGO cursor - provides GO^NOGO testing to determine whether
a curve passes between two endpoints of the cursor bar placed along
the Y axis. This is useful when a device having certain characteristics
must be selected from devices of widely varying characteristics.
H
GAIN cursor - reads out the gain. The GAIN cursor can be used for the
curves measured only when the slave source is in stepgen mode. If this
cursor is placed on two neighboring curves in the curve family at a
specific X axis value or Y axis value according to the sweep direction,
the following calculation will be performed and its result is displayed as
a readĆout:
Y component deviation
STEPGEN deviation
X component deviation
STEPGEN deviation
or
Range and Resolution
In linear sweep mode, the HPU and LPU operate in the range determined by
the resolution and range indicated in Tables 3Ć1 through 3Ć4.
Accordingly, the start, stop and increment values for sweep must be set so
they have same operating range and resolution to satisfy a particular range.
For example, when setting the current, if start, stop and increment are set to
0.0 pA, 44.925pA and 0.025pA, respectively, the 100 pA range is satisfied.
However, when the values are 50.0 pA, 144.925pA and 0.025pA, the 372
automatically switches to the 1 nA range for the values 50.0pA, 144.75 pA
and 0.25 pA.
In logarithmic sweep mode, HPU and LPU are divided into 1, 10 , 20 or 40
equal divisions per DECADE for sweep step operation. Setting must be such
that a predetermined value results determined from the following equation:
Output value (at n
th
data point) = start value x 10
n/m
,
where m is the number of divisions per decade
The divisions per decade for 10 to 40 are shown in Table 3Ć5 through Table
3Ć7. 0.01 though 0.1 is determined by multiplying by 10
Ć2
, and 100 through
1000 is determined by multiplying by 10
+2
. The range settings are shown in
Table 3Ć8. If other values are set, they will be rounded off to the preĆdeterĆ
mined value.
As to delay time and sampling interval, HPU and LPU operate according to
the operating range and resolution indicated in Table 3Ć9.
