The P940 is a modular power instrument intended primarily for aerospace testing. It consists of a 3U rackmount enclosure with main controller, power supply and cooling, and provision for installation of up to eight power, load, switching, or measurement modules.

Features include:

• 1000 watt universal-input 48-volt power supply that is distributed to all modules
• Uniform, rational SCPI command set with Ethernet and USB interfaces
• The P940 can also be controlled manually via front panel color LCD and controls
• All modules include full measurement capability; each module’s measurable values (such as output voltage, current, and frequency) can be read remotely via Ethernet/USB
• Atomic strobe allows a group of settings to be installed simultaneously across modules or multiple chassis
• Four BNC connectors are provided to monitor any voltage or current waveforms
• Voltage and current waveform acquisition across modules and chassis
• UDP realtime data logging

Module functions include:

• Up to 64 channels of DC power supplies, with programmable voltage and current limits
• Up to 64 channels of programmable AC/DC loads, constant current/voltage/resistance
• AC/DC power analysis
• Permanent-magnet alternator simulators
• Relay and LF/RF signal switching modules
• Up to 192 channels of cable fault insertion and measurement
• High voltage power supplies
• Stepper motor, torque motor, solenoid, and hydraulic servo drive
• Cryogenic temperature and helium level measurement
• Additional specialized or custom/combo boards, based on Highland's existing suite of aero-space signal processing functions
