Description
N6781A | 2-quadrant source / measurement module (SMU), 20 V / ± 3 A / 20 W, for N6700C / N6705C
The module is specially designed for the analysis of the discharge processes of batteries. With a DUT (device under test), e.g. For example, an e-book, a cell phone or an MP3 player or another mobile device, the N6781A can analyze the discharge curve and the discharge process of the battery. It is advantageous that this module has a programmable output resistor and a digital voltmeter. The combination of the basic device and the module thus becomes a test system that is unique in the industry for applications such as the testing of the discharge process of a battery in a mobile device. The 14585A software supports this configuration and offers additional measurement options.
The distinguishing feature of the measuring system is that dynamic processes, such as battery discharge, can be measured with high precision without transients or distortions when changing the measuring range. If the battery voltage of the DUT is reduced by the discharge, the SMU automatically and seamlessly selects the current and voltage measuring range that allows the best possible accuracy. A patented technology that Keysight (formerly Agilent's electronic measurement technology) calls "Seamless Measurement Ranging".
Particularly noteworthy with this module N6781A is that e.g. B. the measurement of a very large jump in current can take place without switching a measuring range. Such a measurement is important for the question: How high is the quiescent current in "standby mode" and how high is the inrush current or the inrush current peak. What happens during this time? Especially with the module N6781A, very precise measurements of e.g. For example, the inrush current of a disk drive or the switching on of a Bluetooth headset is possible. Current differences from nA to A range (3A measuring range) can be measured and displayed effortlessly. No other system offers this type of measurement option the market and is patented by Keysight (formerly Agilent's electronic measurement technology), and it can also be determined whether software errors turn a battery-operated device on and off unnecessarily.
In combination with the 18-bit digitizer, the effective resolution of the SMU is increased to 28-bit. No other manufacturer offers this. The high resolution offers you a unique representation of the processes of energy and electricity consumption of your DUT - from nA to A range.
