SDL1000X Programmable DC Electronic Load
Design Features
Steady state operating mode
4-wire SENSE compensation mode function
Simplify complex sequencing using the list operation function
Dynamic test mode up to 25 kHz (CC)
The SDL features four operating modes to provide flexible test
capabilities. In CC mode, the electronic load will sink a constant current,
regardless of the voltage at its terminals. In CV mode, the electronic load
will cause a constant voltage to appear at its terminals. In CR mode, the
electronic load will behave as a xed resistance value. As shown in the
gure, the electronic load will linearly change the current according to
the input voltage. In CP mode, the electronic load will cause a constant
power to be dissipated in the load.
In CC/CV/CR/CW mode, when a load is connected to a power supply, it
will cause a large voltage-drop on the connection lines between tested
instrument and terminals of load. Using remote sense, you can measure
the voltage at the DUTs input terminals, effectively removing the
additional error due to the voltage drop in the connection wires.
You can generate complex load sequences quickly using the list operation function. Here, you can edit the setpoints, dwell time, and slew rate for each step in the
test. *Slew rate can only be edited in CC mode.
The transient test allows switching between two different load values.
A common application is to test the dynamic characteristics of a DC
source or DUT (Device Under Test). The transient test function enables
the load to periodically switch between two set levels (Level A and Level
B). The highest frequency can be set to 25 kHz in CC mode. The highest
frequency can be set to 12.5 kHz in CP modes.
