The 1-kV safety-rated HVD310xA, the 2-kV safety-rated HVD3206A and the 6-kV safety-rated HVD3605A probes provide 1% gain accuracy, a differential-voltage range of up to 1500 V (DC + peak AC), and high offset ranges.
All the HVD3000A probes perform auto-zero functionality without having to first remove the probes from the device under test, ensuring that high-voltage testing will be both consistent and efficient. In addition, the probes automatically detect overloads of both differential- and common-mode input, notifying users of any overload condition through the oscilloscopes’ user interfaces (overload thresholds vary with probe models).
The HVD3605A is safety-rated for 8485V (DC + peak AC) and 6000VRMS for full test coverage of 5kV-class, three-phase electrical apparatus and power electronics. This has a differential-voltage range of 7000V (DC + peak AC) with a 7600V maximum measurable differential voltage before amplifier saturation, and an offset range of up to 6000V along with 100 MHz of bandwidth. The HVD3605A allows probing of AC Line, DC bus, and drive/inverter output voltages at apparatus ratings up to 4160V
The HVD3206A 1500VDC CAT III probe meets the IEC/EN 61010-031:2015 standard, addressing solar PV string-inverter requirements for 1500 VDC inputs, which will become common in utility-scale string inverters with more PV modules on each string and lower installed cost. The HVD3206A has the same 1% gain accuracy and a 2000 VPK differential-voltage range, 120 MHz of bandwidth, and CMRR performance of 85dB from DC to 60Hz and 65dB at 1MHz, falling to 40dB at 5MHz an 30dB at 20MHz.
Serving the full 600V-class requirement for three-phase electrical apparatus, high-voltage DC-DC converters, and 120-V/240-V half-bridge circuit topologies, the 1kV HVD310xA probes come in bandwidths of 25, 80, and 120 MHz with teh same CMRR as the 2kV version. These probes offer a 1500V differential range with an overshoot capability of 2000 VPK and offset capability of 1500V when used with Teledyne LeCroy’s HDO Series oscilloscopes.
All HVD3000A series probes connect to the oscilloscope through the ProBus interface, which brings power and communications to the probe so there is no need for a separate power supply or batteries. Attenuation is automatically selected based on oscilloscope gain range (V/div) setting.
The HVD3102A (1 kV, 25 MHz), HVD3106A (1 kV, 120 MHz), HVD3206A (2 kV, 120 MHz) and the HVD3605A (6 kV, 100 MHz) sell for US list prices of $1,535, $1,865, $2,195, and $3,430, respectively. Some probes are offered in “no-accessory” versions at lower entry-level prices, and some are offered in 6m cable versions.
