Capture Transient Current with Industry-Lowest Noise Differential Sensor

Measurement challenges using a small shunt resistor
A differential probe across a shunt resistor is one of the most common ways to measure your current waveform as well as a current probe and a DMM. A conventional oscilloscope with a differential probe doesn’t have the high sensitivity because of the large noise floor, and the noise floor increases when extending the cable. All of these challenges make temperature testing more difficult.
Unveiled true dynamic characteristics by sub-μV CX1105A ultra-low noise differential sensor
The Keysight CX3300 Series device current waveform analyzer is the new solution which enables precision dynamic current and voltage measurement. The CX1105A’s ultra-low noise differential sensor supports low noise and wide dynamic range measurement from 400 nV to 2.5 V up to 100 MHz bandwidth. It has a dedicated 1 m cable that supports the low noise floor — useful for accurate temperature testing.
