real batteries show different characteristics depending on the type of battery and its charging condition. capacity, open circuit voltage (voc) and equivalent series resistance (esr) are important battery characteristics that depend on its state of charge (soc). the optional r&s®ngm-k106 functionality allows users to simulate the behavior of batteries under different charging conditions, e.g. when powering a dut.
the r&s®ngm200 power supplies offer the high-speed fastlog functionality to capture voltage and current measurement results. this data can be stored on an external usb storage device or can be transferred to an external pc via usb or lan. with an acquisition rate of up to 500 ksample/s, voltage and current results are available every 2 μs. instead of the readback voltage, also the voltage measured by the optional digital voltmeter functionality (r&s®ngm-k104) can be logged with 500 ksample/s. using the two-channel r&s®ngm202, the data acquisition can run on both channels in parallel.
with this high-speed acquisition, even spikes in the microsecond range that cannot be detected with slower instruments, can be detected in min./max. values.
like other power supplies, the r&s®ngm200 instruments measure the voltage supplied to the dut. in addition, the r&s®ngm-k104 option activates a port that allows the internal digital voltmeter to be connected to any other point in the customer’s circuitry. in many cases, an additional digital multimeter is not necessary.
replaces an additional dmm
with a resolution of up to 6 ½ digits when measuring voltage, current and power, the r&s®ngm200 power supplies are perfect for characterizing devices that have low power consumption in standby mode and high current in full load operation. two voltage measurement ranges and four ranges to measure current provide a high accuracy and resolutions down to 1 µv/10 na.
handles fast load changes
consumer electronics such as mobile phones and iot devices require very little power in sleep mode. however, the current increases abruptly as soon as the device switches to transmit mode. a power supply used to power such duts must be capable of handling load changes from a few µa to the ampere range without creating voltage drops or overshoots.
