The 9140 series list mode programming features are useful for repetitive testing or other applications requiring a specific sequence of voltage and current settings. Further expanding test sequence capabilities, list mode programs work with channel combine, coupling, and on/off delay features for highly configurable and customizable testing sequences.

Each list mode program contains up to 100 steps each. Step parameters can be configured from the front panel or on a computer and loaded into the power supply's internal memory.

List Memory is shared across all three channels, providing the capability to reference and run the same list or different lists simultaneously.

Channel coupling links the output states between multiple channels. ON/OFF output delays for each channel can be set from zero delay to 1 hour in 0.1 increments.
Microcontrollers and other processing devices often require specific startup power sequences in order to function properly. The 9140 Series' coupling mode, output delays, and slew rate can be configured to produce power up sequences for microcontroller testing applications.

• Provides three individual and isolated power supplies in one compact, space saving form factor
• LXI compliant LAN, USBTMC-compliant/USB Virtual COM Port selectable, and optional GPIB Interface
• LabVIEW™. IVI-C, and IVI.NET drivers simplify system development and integration
• Digital I/O terminal with remote Inhibit and voltage fault protection capabilities
• Rear panel output terminals with remote sense for each channel

Log voltage, current, or both at a user-defined sampling Interval adjustable from 0.2 seconds to 5 minutes directly to an external USB flash drive. Data points for all three channels are saved as a CSV file with date and time stamp.

The 9140 Serles provides a built-In web server that allows users to configure, monitor, and control basic settings of the power supply from a web browser on a computer connected to the same local area network.
