Confidently measure dynamic current and voltage

The Internet of Things (IoT) requires various devices to perceive and process data, and connect to the network. Therefore, the Internet of Things has significantly increased the number of embedded electronic components. The characterization of power rail current and voltage is crucial for revealing the working principle of devices, thereby improving performance and optimizing circuit design to ensure reliability.

The Keysight CX3300 series is an integrated measurement and analysis solution designed to address your power rail, power transmission network, and power integrity issues. The CX3300 series integrates the bandwidth and sampling rate of an oscilloscope, the sensitivity of a universal dock, and the extended measurement recording of a data logger to reveal accurate current and voltage waveforms.

Immediately identify rare anomalies from data exceeding one TB

The Abnormal Waveform Analysis (AWA) function is a machine learning technique embedded in the Keysight CX3300 waveform analyzer. It helps you capture repeated voltage and current waveforms exceeding one TB. You can immediately identify and analyze intermittent abnormal signals and events in the waveform that cannot be manually analyzed. The abnormal waveform analysis function accelerates feature analysis, validation, and debugging on both mainframes and personal computers.

Power rail characteristics

The Internet of Things (IoT) requires various devices to perceive and process data, and connect to the network. Therefore, the Internet of Things has significantly increased the number of embedded electronic components - optimizing cost, energy efficiency, and reliability is crucial.

The next generation of IoT devices can operate for a long time at lower power supply voltage and power. These devices have integrated capabilities such as functionality, performance, network connectivity, and network security. These devices typically use power supplies, DC/DC converters, power management integrated circuits ASIC/MCU、 Configuration of sensors, displays, wireless circuit modules, etc. The device is programmed to work intermittently during idle/sleep/power on (wake-up) and activation mode transitions to extend its operating time at low power supply.

The characterization of power rail current and voltage is crucial for revealing the working principle of devices, thereby improving performance and optimizing circuit design to ensure reliability. For example, the characterization of power rail current and voltage helps R&D engineers complete the following tasks:

Verify circuit design based on component gap, peak value, and inrush current

Monitor the power consumption trend of key equipment

By characterizing, debugging, and optimizing power consumption, as well as firmware power management, to control active to sleep operation

Design power rail with precise current and voltage waveforms to ensure power integrity

Identify device behavior issues that cannot be detected by voltage measurement

Detecting malicious code execution, such as side channel attacks used for network security

How to solve the challenge of power orbit

The current waveform rapidly changes from sub μ A to milliampere according to the working mode of the device. The digital multimeter (DMM), current probe, and differential probe on parallel resistors are standard tools for measuring current. However, due to the trade-off between bandwidth, sampling rate, sensitivity, and noise, these traditional instruments are gradually unable to capture dynamic current and voltage waveforms on the power rail.

The CX3300A series - CX3322A with dual channels and CX3324A with four channels - is a solution that helps measure dynamic current and voltage characterization. They integrate the bandwidth and sampling rate of oscilloscopes, the sensitivity and low noise of multi-purpose docks, and the long-term measurement advantages of data loggers into a single instrument. It enables you to characterize the power rail, power integrity, or dynamic current and voltage behavior of a wide range of devices more accurately, precisely, and quickly than other traditional methods.

Dynamic current measurement

Usually, a universal dock oscilloscope with a current probe or differential probe is used to measure current, but there are trade-offs in bandwidth, sampling rate, sensitivity, and noise. The comparison between CX3300A and traditional measuring tools is shown in Figures 5 and 6. In some cases, multiple instruments are required for comprehensive characterization, or a single instrument is used for characterization. However, identifying potential design failures solely with a single instrument is challenging.

CX1101A Single Channel Current Sensor

CX1101A is a current sensor used in various applications. The unique current sensing technology suppresses high-frequency noise.

CX1102A Dual Channel Current Sensor

The CX1102A dual channel current sensor supports simultaneous measurement in two different measurement ranges. For example, the main channel is set to a range of 20 mA, while the secondary channel is automatically set to a range of 200 μ A. This setting supports sub μ A measurement, which is 50 to 100 times the range of the main channel compared to the secondary channel. This current sensor is very useful in low-power applications because it has intermittent operation between sleep/standby and active states.

The CX1105A ultra-low noise differential sensor measured the differential pressure across parallel resistors on the evaluation test board. It performs non-invasive current measurement. The measurable voltage is converted into the current on the CX3300A host by inputting the value of the parallel resistor. Figure 13 shows an example of measuring a 1 mV peak waveform, with low noise and mild testing conducted inside the chamber.
