Current Probe

AVCP-series current probes are based on a series resistor and differential amplifier which generates an output voltage proportional to the current flowing through the resistor. Large series resistors are used to create a large voltage drop in order to measure extremely low currents in the order of uA and mA. Unlike current probes based on Hall effect sensors, AVCP-series current probes do not need to be demagnetized (degaussed) and can be used more easily over long periods of time.

Features and Benefits

  • Resistor-based design
  • Ideal for low-current measurements
  • Compatible with most commercial oscilloscopes and digitizers
  • Ideal for pulsed measurements
  • No need for demagnetization (degauss)
