• Independently programmable channel outputs
• Precision voltage and current read back
• Self-calibration for high accuracy

The Flexstar Network Power Margin board is highly evolved to provide the highest levels of precision and repeatability. Up to four independently programmable channel outputs deliver up to 5 amps per channel with voltage ranging from 0V to 15V in 7.5mV increments.

A built-in microprocessor manages the communication, addressing, internal voltage algorithms and self- calibration, ensuring tight control of outputs. An on- board memory enables acquisition of power samples with programmable sample rates, useful for capturing snapshots of power profiles.

Read back of voltage and current is very precise: current measurement over the full 5A range has a 2mA resolution and an accuracy of +/- 1% of full scale; voltage measurement ranges from 0V to 15V with a 3.6mV resolution and an accuracy of +/- 0.5% of full scale.

Slew rates can be programmed in 1-millisecond increments allowing the development of test scripts to meet the requirements of a wide range of applications. Additionally, all channels can be programmed for synchronous slew.

The Flexstar Network Power Margin Board enables flexible, accurate and repeatable power margining for any storage device under test.
