The world’s first instrument that enables every electronics engineer to precisely visualize never before seen wideband low-level current waveforms. Keysight Technologies Device Current Waveform Analyzer CX3322A 2 Channel CX3324A 4 Channel Data Sheet
When evaluating or debugging low power devices, most test engineers use a similar set of instruments: power supplies, multimeters, oscilloscopes, spectrum analyzers, network analyzers, function generators, etc. Measurements made by these instruments are mostly based on “voltage waveform measurements”. However, a recent increase in demand for power reduction has resulted in an increase in current waveform measurement opportunities to precisely estimate low-level current and power consumption. In order to reduce the power consumption of your product, you need to know when, where and precisely how much current is consumed. The CX3300 series of Device Current Waveform Analyzers can visualize wideband low-level, previously unmeasurable or undetectable, current waveforms.. The main frame has either 2 or 4 channels to receive signals from the Current Sensors and digitize them by a maximum of 1 GSa/s and 14-bit or 16-bit wide dynamic range. There are three types of Current Sensors that can detect a wide range of dynamic currents from 100 pA level up to 10 A, with a maximum of 200 MHz bandwidth. There are six types of detachable Sensor Heads designed to provide an appropriate choice of connection to the DUT (Device under Test) and they are available for two of the three types of Current Sensors. Captured waveforms are displayed on the WGXA 14.1” LCD with multi touch screen. The CX3300 series can also measure dynamic voltage waveforms by using a Passive Probe Interface Adapter connected to a measurement channel, so that power consumption waveform can also be calculated and displayed. The CX3300 series also features useful analysis capabilities such as an Automatic Power and Current Profiler, a Power Measurement Wizard, FFT Analyzer and Statistical Analysis functions, which accelerate the analysis of the measurement data without the need to use external analysis utilities. With this new and powerful analyzer, you can achieve critical mission on power and current consumption reductions by precisely measuring, previously unmeasurable or undetectable, wideband low-level current waveforms.
