Model 2200-20-5 delivers up to 20V, 5A, 100W; Model 2200-30-5 delivers up to 30V, 5A, 150W; Model 2200-32-3 delivers up to 32V, 3A, 96W; Model 2200-60-2 delivers up to 60V, 2.5A, 150W; and Model 2200-72-1 delivers 72V, 1.2A, 86W.

The high output (1mV) and measurement (0.1mA) resolution of the Series 2200 power supplies make them well-suited for characterizing low power circuits and devices in applications such as measuring idle mode and sleep mode currents to confirm devices can meet today’s ever-more-challenging goals for energy efficiency. Remote sense terminals on the back panel and less than 5mVp-p noise help ensure that the voltage programmed is the voltage that the supply actually outputs. A dual-line display shows both the programmed values and actual outputs for a continuous indication of the status of the power delivered to the load.

Each model provides 40 onboard memory locations for storing frequently used test setups for later recall and reuse. In addition, a built-in list mode function supports the programming and storage of up to seven custom test sequences of up to 80 steps. Once saved, a sequence can be triggered to run manually using the instrument’s front panel keys, automatically via an external trigger, or by using programmable interface commands.
Several Series 2200 features help protect DUTs from damage during testing, including a programmable voltage limit value that prevents the supply from outputting excessive voltage (even if a voltage higher than the limit is entered into the instrument) and a programmable over-voltage function that causes the output to drop to less than 1V if the over-voltage limit is reached. These limits are in addition to the current limit setting function, which controls the level of current that can flow into the DUT. Also, a programmable timer can be used to turn off the output after a specified time interval, so tests can be preprogrammed to run unattended without worrying about excess voltage or power being applied to the DUT for an extended period of time.

Multiple methods for adjusting the supplies’ voltage and current settings are provided, including a direct-entry numeric keypad on the front panel. In addition, a rotary knob with adjustable step size simplifies studying the response of a device-under-test (DUT) to voltage or current changes. The units can be controlled over either a standard GPIB or USB interface. The USB interface is test and measurement class (TMC) compliant, so users can employ the standard SCPI command syntax. Standard instrument drivers are included to simplify integrating the power supplies into an automated test environment.
