Keysight (formerly Agilent) 66319B dual-output mobile communication DC power supply provides two outputs for measuring the main power supply and charger circuit test at the same time. Customers can use the same device to test mobile phones and chargers. This feature helps save rack space (two outputs are provided in a half-rack device) without the need for two separate power supplies. The outstanding voltage transient response minimizes the device shutdown caused by the transient voltage drop in the test line, ensuring the maximum test system throughput.
66319B provides a new function developed by Keysight (formerly Agilent), which enables cellular phone manufacturers to automatically detect open circuit and intermittent open circuit sensor line connections. By detecting the open-circuit sensor line connection, users can prevent improper charger calibration, incorrect test results, and low-voltage mobile phones from shutting down due to large transient voltage drops. This diagnostic function can help manufacturers avoid selling low-quality products and achieve more reliable testing and accurate measurements.
