Use One Optimized Probe For Every In-Circuit 60 V GaN Measurement

Optical probes are too expensive and/or have too much performance for the lower dV/dT and common-modes present in 60 V designs. High voltage differential probes are not performance optimized for this application. Only one differential probe – the Teledyne LeCroy DL-HCM Series – is optimized for 60 V GaN probing.

• 60 V common-mode voltage rating, 80 V differential voltage rating
• Measure 1 ns rise times with up to 1 GHz system bandwidth (using a 1 GHz oscilloscope)
• Easily accessibility with small size and a wide variety of tips and leads

Faithful Reproduction of Gate-drive and Device Output Signals

DL-HCM series probes have the high performance required to faithfully measure your high-speed gate-drive and device output signals.

• Low additive noise due to low, switchable attenuation
• Most faithful signal reproduction with 0.5% gain accuracy, 0.1 dB LF flatness, 80 dB CMRR and low additive overshoot
• Gate-drive measurements with 8.9 Vmax or 20 Vmax dynamic range, and low input loading (200 kΩ // 0.6 pF)
• Device Output measurements with 80 Vmax dynamic range

Dual-purpose to Also Measure DC Link and System Output Signals

Measure every in-circuit signal, regardless of where it is in your circuit, with switchable attenuation for higher voltages.

• DC Link ripple measurements using minimum 1.6 Vp-p measurement range with only 3.25 mVRMS additive noise
• System Output measurements (line-ref or line-line) with 80 Vp-p differential capability
• 60 V common-mode rating

Lower-cost High Voltage Differential Probes (HVD Series) For Lower Bandwidth Measurements

System output measurement often don’t require high bandwidth, but still require high accuracy, low noise, and good noise immunity (high probe CMRR). If probe pricing is a challenge, HVD Series probes can balance price and performance for some GaN system measurements.

• Device Output measurements with 400 MHz bandwidth model
• System Output measurements with 120 MHz to 400 MHz models
• Great price vs. performance — low noise and 65 dB CMRR at 1 MHz (30 dB or better than competitive probes)
• 1% gain accuracy (two times better than competitive probes)
• Common-mode rated to 1 kV, 2 kV or 6 kV

Capture Every Detail with High Oscilloscope Resolution at Full Bandwidths

Teledyne LeCroy High Definition Oscilloscopes (HDO®) provide 12 bits of resolution all the time at full oscilloscope bandwidth ratings. Once you use a Teledyne LeCroy HDO, you’ll never want to go back to using another oscilloscope.

• No tradeoff of resolution, sample rate or bandwidth
• Clean, crisp waveforms
• More signal details
• Unmatched measurement precision

More Capability for Inverter Subsection and System Test

Teledyne LeCroy oscilloscopes and software application packages provide faster and more complete debug of half-bridge, full-bridge and cascaded H-bridge inverter subsections and systems.

Optical Probes (HV) for SiC Gate-drive and Device Output Signals

Optical isolation provides the best noise immunity at the fastest dV/dt while also providing safe operation, high signal fidelity and square header connections to in-circuit signals in SiC designs

• 350 MHz bandwidth (1.1 ns rise time) with 160 dB CMRR rating for best noise immunity
• Highest accuracy (1.5%) with precision gain calibration and low drift
• Interchangeable tips to permit measurement of both gate-drive and device output signals
• Square header connection to SiC signals and very flexible tips make it easy to connect to signals in SiC designs

Highest Performance 6 kV Common-mode HV Differential Probe for 5 kV Class Apparatus (HVD3605A)

The Teledyne LeCroy HVD3605A high voltage differential probe is the only HV differential probe worth considering for >1500 V SiC measurements and combines exceptional noise immunity with high performance.

• 6000 VRMS common-mode safety rating
• Uniquely noise immune with 50 dB CMRR at 1 MHz in highest voltage range – no comparable probe comes close.
• Only probe that permits AC line, DC link, and system output voltage probing up to 4160V apparatus ratings
• Industry's best offset capability (6000 V)
• 1% gain accuracy

1500 V Common-mode Safety-rated HV Differential Probe per IEC/EN 61010-031:2015

Utility grid-tied solar photovoltaic (PV) inverters, uninterruptible power supplies (UPS) and welding systems commonly use 1500 Vdc buses to minimize system cost. Teledyne LeCroy’s HVD3206A or HVD3220 are ideal for this application.

• 1500 VDC (CAT III) and 2000 V (DC+peak AC) (CAT I) safety rating – unique in the industry
• Low-attenuation (500x) with 2000 V differential voltage rating
• 120 MHz or 400 MHz bandwidth ratings
• 65 dB CMRR at 1 MHz (50x better than competitive 1 kV-rated probes)
• 1% gain accuracy

Teledyne LeCroy oscilloscopes and software application packages provide faster and more complete debug of cascaded H-bridge and multi-level cascaded H-bridge inverter subsections and systems.

• 8 channel oscilloscopes (16 channels using OscilloSYNC) provide capability to view all switching events at one time
• Powerful, deep toolbox with many automated timing and other measurements
• Application specific power packages make it easy to correlate control events to power events, or even to a single device switching cycle
