Introduction

The HVD3102 and 3106 high-voltage active differential probes are safe, easy-to-use, and ideally
suited for power electronics measurements. The probes feature:
Differential voltage measurement capability in high common-mode (up to 1000Vrms)
l
environments.
Exceptional common-mode rejection ratio (CMRR) across a broad frequency range
l
Wide differential voltage range – 1500Vpeak rated and 2000Vpeak before amplifier
l
saturation to permit capture of short duration overshoots
High offset capability at both 50x and 500x attenuation settings provides maximum
l
flexibility for capturing gate drive and control signals floating on a 1000Vdc bus
1% DC and low frequency gain accuracy
l
ProBus interface with automatic scaling
l
Auto Zero capabilities

The HVD3102 probe (25 MHz, 1000Vrms) and HVD3106 probe (120 MHz, 1000Vrms) are ideal
for power electronics applications, where the reference potential is elevated from ground. Each
probe is supplied with a complete set of lead accessories and a soft accessory case. The main
differences between the two probes is the probe bandwidth (25 MHz vs. 120 MHz).
The CMRR for the probes is exceptional out to very high frequencies. This greatly assists in
measurement of signals in the noisy, high common-mode environments common to power
electronics. The high 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.
Probe specifications are provided for using the probe within a 1500Vpeak differential voltage
range. However, the probe can be safely operated above this range. Up to 2000Vpeak, the probe
will display the signal, but the probe specifications cannot be guaranteed. However, in this
range, the probe is operating below the saturation point of the amplifier, and very reasonable
results can be expected. The V/div range for each probe can be set up to 400V/div (3200Vp-p
displayed over all 8 vertical oscilloscope grid divisions).
