Emulate the Response of a Battery
Test a circuit or device under the most realistic conditions by applying a test source with the output
resistance that is equivalent to the output resistance of the actual source that will be used to power
the circuit or device. For example, a battery has a varying internal resistance, and a device powered
by a battery will have a voltage applied to the device that is reduced by the voltage drop across the
battery’s internal resistance. Versions of the Series 2260B supplies can have an internal resistance up
to 5.9W to simulate devices such as a lead-acid battery.
10V @ 4Ω load
Internal Resistance = 0Ω
I = 2.5A
Internal Resistance = 0.9Ω
I=10V/(4Ω + 0.9Ω) = 2.04A
V
Load
= 10V – (2.04A*0.9Ω) = 8.16V
Internal Resistance = 1.8Ω
I = 10V/(4Ω + 1.8Ω) = 1.72A
V
Load
= 10V – (1.72A*1.8Ω) = 6.90V
Internal Resistance = 2.7Ω
I = 10V/(4Ω + 2.7Ω) = 1.49A
V
Load
= 10V – (1.49A*2.7Ω) = 5.98V
Use the programmable internal resistance to simulate a battery’s output. In this example, a
Model 2260B-80-13 power supply is simulating a 10V battery whose internal resistance is 0W,
0.9W, 1.8W, and 2.7W. The resulting voltage at the output terminals drops from 10V to 5.98V
due to the voltage drop across the internal resistance of the battery.
Create Custom Voltage Source Waveforms
An internal test sequence mode allows the Series 2260B supplies to output a set of voltage levels for
varying time intervals at each level. The test sequence can be stored and used repeatedly to deter-
mine DUT performance at number of voltage levels. In addition, the analog input control can be
used to create voltage profiles that simulate how a battery responds to a fast changing load current
requirement such as a large inrush current. Also, generate a combined DC output level with an AC
signal superimposed on it to test how a circuit responds to noise on its DC power source. The analog
input control parameter can be either a voltage input or a resistance input. With this analog control
capability, numerous types of DC supply signals can be generated to test circuits and devices under a
wide range of circumstances.
