Introduction
Specifications
Measurement mode details
Agilent B1500A supports the following measurement modes:
• Staircase sweep
• Multi-channel sweep (EasyEXPERT does not support VAR1’)
• Pulsed sweep
• Staircase sweep with pulsed bias
•IV sampling
• High speed IV sampling
• CV sweep
• C-t sampling
• C-f sweep
• List sweep
• Linear search (supported by FLEX command)
• Binary search (supported by FLEX command)
Each SMU can be set to VAR1 (primary sweep), VAR2 (secondary sweep), VAR1’
(s
ynchronous
sweep), or CONST (constant voltage/current source).
•VAR1
Primary sweep controls the staircase (DC or puls
ed) voltage or current sweep.
Maximum number of VAR1 steps: N
1
= 1001
•VAR2
Subordinate linear staircase or linear pulsed sweep
. After primary sweep is
completed, the VAR2 unit output value is changed.
Maximum number of VAR2 steps: N
2
= 1001 (condition: 1 ≤ N
1
× N
2
≤ 128128)
•VAR1’
Staircase or pulse sweep synchronized with the VAR1 sweep. Sweep is made
with a user specified r
atio and offset values.
VAR1’ = a × VAR1 + b
“a” is the u
ser specified ratio, and “b” is the use
r specified offset value.
