Device current waveform analyzer visualizes previously unmeasurable low-level current waveforms.
Whenever a semiconductor or system changes state, there’s a good chance that the current it draws will also change. A typical example is a cell phone, which draws more current when you make a call or turn on Wi-Fi. Digital circuits also need more current when switching states than when in idle states.
The most common way of looking at current is either with an oscilloscope connected across a shunt resistor or with a current probe around a wire or cable. You have to configure the oscilloscope to display in amperes or calculate the current yourself. But you often have to measure small currents or small changes in current. With Keysight’s CX3300 Device Current Waveform Analyzer, you get up to 200-MHz bandwidth, 14-bit or 16-bit resolution, and system noise low enough to measure the small amounts of current drawn by today’s devices. The CX3300 comes in two models: two-channel and four-channel.
