• The pulse simulator allows cost-effective testing of large solar panels compared to steady-state solar simulators.
• Tests can be repeated without altering the temperature of solar cells, eliminating the need for thermocouple testing.
• No adjustments are needed to maintain beam uniformity, which depends on the distance from the target plane to the lamphouse.
• The spectrum is determined by the lamp's current density, negating the need for complex spectral filtering.
• Components can be rearranged to suit changing needs, with the lamphouse mountable on the ceiling to save space.
• Low maintenance is required, with lamp changes taking only 1 to 2 hours.

• Measures current-voltage characteristics of solar arrays up to 5 meters (16 feet) in diameter.
• Multiple pulse mode enables accurate testing of solar cells with long storage times, such as Back Surface Field cells.
• Measures a minimum of 40 data points per pulse and up to 200 in multi-pulse mode.
• Includes an electronic load for continuous sweep biasing from short circuit to open circuit.
• Capable of biasing selectable segments of the I-V curve for multi-pulse testing.
• Xenon lamp current density is optimized to match the solar spectrum according to NASA Space Vehicle Design Criteria SP8005.
• Optional extended range accessory units are available to increase current or voltage range to 200 Volts or 50 Amps.
