New 60 V common mode differential probes now available

30 October 2020

New 60 V common mode differential probes from Teledyne LeCroy are ideal for lower voltage gallium nitride (GaN) power conversion measurement with the highest accuracy, best common mode rejection ratio (CMRR) and lowest noise. The 60 V of common mode is well suited for handling any float of the battery and bulk/absorption voltage during charging, while an 80 V differential input range with 1 GHz of bandwidth provides margin for any overshoot.

The DL-HCM probes are calibrated for high-precision measurements to within 0.5% at DC and 0.1 dB flatness from DC to 100 MHz. This ensures high accuracy top and base voltage level measurement of pulse-width modulated signals. The precision gain calibration capability furthers measurement precision by improving the Source: Teledyne LeCroySource: Teledyne LeCroygain accuracy and removing small offset drifts from the measurement configuration.

The CMRR is exceptional to very high frequencies, providing for the best measurement performance when measuring very fast slew rate (high dV/dt) pulse-width modulation signals typical of GaN devices and systems. Exceptional CMRR, combined with low probe noise and high offset capability, makes the probes capable of measuring very small control signals floating on high common mode voltages.

The 60 V common mode differential probes provide the perfect combination of high performance and flexibility for connecting to any device under test. An optional accessory kit and high temperature solder-in tip are available for further connectivity options.
