Ideal Probes for up to 48V GaN Power Conversion

60 V of common mode and 80 V differential input range with 1 GHz of bandwidth, make these probes ideal for lower voltage GaN power conversion measurements. The 60 V of common mode is well suited for handling any float of the battery and bulk/absorption voltage during charging, while the 80 V differential input range provide margin for any overshoot.

Highest Accuracy

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 gain accuracy and removing small offset drifts from the measurement configuration.

Lowest Noise and Highest Rejection

The Common Mode Rejection Ratio (CMRR) is exceptional to very high frequencies. This provides for the best measurement performance when measuring very fast slew rate (high dV/dt) PWM 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.

Wide Variety of Tips

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.
