Note:
These parameters are used for Automatic Test ONLY .
Immediate Current Value
Set the current level via front panel or by sending SCPI command CURR n . If the load is in CC mode, the new current
level setting immediately changes the input at a rate determined by the slew rate. If the load is not in CC mode, the
current level setting will be saved for use until mode is switched to CC mode.
Transient Current Level
A/B transient current level can be set on the front panel or by remote operation. The load can continuously toggle
between the two levels when transient operation is turned on.
Set Slew Rate
The current slew rate determines the rate at which the input current to a module changes to a new programmed value.
You can set the current level’s rise/fall slew rate on the front panel or by remote operation. The programmed slew rate
is immediately in effect to the triggered and transient current level changes.
Slew Rate Measurement and Actual Transition Time
Current slew rate is defined as the change in current over time. A programmable slew rate allows a controlled transition
from one load setting to another. The actual transition time is defined as the time for the input to change from 10% to
90%, or 90% to 10% of the programmed current values. The graph below illustrates slew rate measurements.
