Sweep Operation
Model 2520 User’s Manual
Sweep types
The three basic sweep types described in the following paragraphs include:
•
Linear staircase
•
Logarithmic staircase
•
Custom
NOTE
Linear and logarithmic staircase sweeps are available both from the front panel
and via remote. Custom sweeps can be performed only via remote.
Linear staircase sweep
As shown in
, this sweep steps from a start current source value to an ending
(stop) current source value. Programmable parameters include the start, stop, and step
source current levels. (This example shows the DC mode of operation.)
When this sweep is triggered to start, the current source output will go to the start source
current level. The output will then change in equal steps until the stop source level is
reached. The time duration at each step is determined by the time it takes to perform the
measurement, which includes both the pulse width and the pulse delay.
