The PINTECH N1070Apro is a 50MHz high-voltage differential oscilloscope probe designed for engineers, technicians, and lab users who need to measure differential signals up to 7kVp-p with 1000X or 100X attenuation and a standard BNC oscilloscope connection.
Recommended For
- Engineers and technicians measuring floating high-voltage nodes in power electronics, such as inverter outputs, switch-mode power supplies, motor drives, or offline mains sections, where a true differential probe is safer and more appropriate than a standard ground-referenced probe.
- Bench users who already have a standard 1 MΩ BNC oscilloscope and need a differential accessory that works across different scope brands, rather than a probe tied to a proprietary interface.
- Users who need better differential measurement fidelity than the two-passive-probes-plus-math workaround, especially when the signal of interest is small relative to common-mode voltage.
- Lab and field-debug users who want flexible powering options for longer measurement sessions or portable work, since this model supports external power and battery operation.
Real-World Use Scenarios
- Checking inverter, motor-drive, or half-bridge switching nodes on a bench oscilloscope where neither point is at ground. The user is trying to see the true differential waveform without shorting a floating high-side node to earth. The likely outcome is a usable waveform for switch timing, overshoot, and ringing checks that would be unsafe or misleading with a standard ground-referenced probe.
- Measuring high-voltage waveforms inside power supplies, PFC stages, or offline converters during repair or validation. The user is trying to compare drain-to-source, gate-related, or bus-related behavior while keeping the oscilloscope safely referenced through the probe. The likely outcome is clearer diagnosis of switching behavior and abnormal transients than with two single-ended probes or improvised floating setups.
- Looking at phase-to-phase or phase-to-neutral voltages in three-phase equipment such as VFDs and industrial drives. The user is trying to verify PWM output shape, switching imbalance, or startup behavior on lines that cannot be safely clipped to scope ground. The likely outcome is practical visibility into drive output behavior for commissioning or troubleshooting, provided the signal stays within the probe's voltage limits.
- Capturing fast edges and ripple on high-common-mode power electronics nodes during design debugging. The user is trying to separate the small differential signal from a large DC bus or switching common-mode voltage. The likely outcome is more believable measurements of ripple, ringing, and transition details than subtracting two scope channels, especially when channel matching is not ideal.
- Using a standard BNC oscilloscope to inspect floating or non-ground-referenced circuits in a lab, service bench, or education setting. The user is trying to extend a normal bench scope into jobs that involve mains-derived or isolated high-voltage sections without buying a specialized isolated oscilloscope. The likely outcome is broader measurement capability, but with the tradeoff that attenuation and high-voltage focus make it less suitable for very small low-level signals.

Reference Q&A
Q: Should I choose the PINTECH N1070Apro or a 25MHz high-voltage differential probe?
A: Choose the PINTECH N1070Apro when you need both high-voltage headroom and enough bandwidth to see switching edges more clearly. The N1070Apro is positioned as a 50MHz, 7kVp-p differential probe with 100X/1000X attenuation and ±0.5% accuracy, while common 25MHz alternatives are typically intended for lower-speed measurements and often offer lower voltage range. A 25MHz model is more suitable for slower waveforms and basic mains or inverter checks. The N1070Apro is the better fit for broader power electronics work where voltage margin and edge fidelity matter more than minimum cost.
Q: Is the PINTECH N1070Apro a better choice than a 100MHz differential probe?
A: Choose a 100MHz probe if your main goal is capturing faster transients, sharper switching behavior, or higher-frequency content. Choose the PINTECH N1070Apro if your priority is 7kVp-p measurement range with solid baseline accuracy for general high-voltage oscilloscope work. In official product lineups, 100MHz probes are usually the step-up option for faster signals, while 50MHz models remain a practical choice for many power conversion and high-voltage applications. The trade-off is simple: the N1070Apro favors voltage range and broad compatibility, while a 100MHz model favors additional signal detail.
Q: How does the PINTECH N1070Apro compare with a Siglent high-voltage differential probe?
A: The PINTECH N1070Apro is the more universal choice if you want a standard BNC-connected probe that can work across many oscilloscopes without relying on a brand-specific probe interface. Siglent's high-voltage differential probe range includes models with higher bandwidth and SAPBus integration, which can be more attractive in a Siglent-centered setup or when you need more advanced bandwidth options. Choose the N1070Apro for cross-scope compatibility and 7kVp-p coverage in a straightforward 50MHz class. Choose a Siglent model if you want tighter alignment with Siglent instruments or need a higher-bandwidth option from the same vendor ecosystem.
Q: Should I buy the PINTECH N1070Apro for portable field checks or use a bench-focused higher-performance probe?
A: Choose the PINTECH N1070Apro when portability and flexible powering matter, because it supports battery or adapter operation and uses a standard BNC interface that is easy to pair with many scopes. A higher-performance bench-focused probe is the better choice when your measurements are done in a fixed lab setup and you need more bandwidth, deeper ecosystem integration, or more specialized scope-side features. The N1070Apro is better suited to mixed environments where convenience and compatibility are part of the buying decision, while bench-oriented premium probes are better suited to maximum waveform detail.
Q: Is this probe suitable for measuring high-voltage differential signals on a standard oscilloscope?
A: Yes, if your oscilloscope uses a standard BNC input and you need isolated differential measurement rather than a basic ground-referenced passive probe. The N1070Apro is positioned for high-voltage differential work with a 7 kVp-p maximum differential rating, 50 MHz bandwidth, and 100X/1000X attenuation. The main trade-off is that it is for electrical measurement tasks, not general low-voltage bench probing, so buyers should confirm that the voltage range and bandwidth match their use case.
Q: Who is this probe best for?
A: This probe is best for engineers, technicians, and advanced electronics users who need to observe floating or high-side voltages safely on an oscilloscope. It makes more sense for power electronics, inverter, motor drive, SMPS, and similar high-voltage diagnostic work than for hobby-level low-voltage signal checks. Buyers who mostly test low-voltage digital signals may not benefit from a dedicated high-voltage differential probe.
Q: What is the main trade-off of a 50 MHz high-voltage differential probe like this?
A: The main trade-off is safety and voltage capability versus top-end signal speed. A 50 MHz differential probe is a practical fit for many power and industrial measurements, but it is not the best choice for fast RF work or very high-speed digital edge analysis. In return, you get high-voltage differential measurement capability, switchable attenuation, and compatibility with standard BNC oscilloscopes.
Q: Is the 100X/1000X attenuation useful in real buying terms?
A: Yes. Switchable 100X/1000X attenuation makes the probe more flexible across different voltage ranges and helps match measurement sensitivity to the signal being tested. The trade-off is that higher attenuation reduces the displayed signal amplitude, so users need an oscilloscope with enough sensitivity and should verify scaling carefully during setup.
Q: Is this a better fit than a standard passive BNC probe?
A: It is a better fit only when you need true differential high-voltage measurement. Compared with a standard passive probe, this type of probe is better for floating measurements and higher-voltage applications, but it is more specialized and usually less necessary for routine grounded, low-voltage oscilloscope work. Buyers should choose it for measurement safety and differential capability, not as a general replacement for every probe.
Q: Who is this differential probe suitable for?
A: This probe is most suitable for bench users who need to measure floating or high-side voltages with a standard BNC oscilloscope. Based on the product data, it fits work such as mains-level, inverter, motor-drive, and power-electronics troubleshooting where a grounded passive probe is not appropriate. It is less suitable for low-voltage general-purpose probing, and it is not a substitute for proper high-voltage safety practice.
Q: Is it worth buying instead of using two regular probes and math mode?
A: It can be worth buying if you regularly measure non-ground-referenced or high-voltage differential signals. A dedicated differential probe is the safer and more practical choice than using two single-ended probes with scope math, especially when common-mode voltage is high. The trade-off is that this model is specialized: its 100X/1000X attenuation and 50 MHz bandwidth make more sense for power and HV measurement than for small-signal everyday bench use.
Q: What are the main trade-offs of this probe?
A: The main advantages are high-voltage differential measurement, dual attenuation options, standard BNC compatibility, and battery or adapter power. The main trade-offs are moderate bandwidth at 50 MHz, high attenuation that reduces usefulness for very small signals, and the need to manage probe powering. In short, it is better matched to power electronics and mains-related measurement than to high-speed digital debug or low-level precision signal work.
Q: Is 50 MHz bandwidth enough for this kind of probe?
A: 50 MHz is generally enough for many mains, switching power supply, inverter, and motor-drive measurements, but it is not a strong fit for higher-speed edge analysis or fast digital buses. The product's 7 ns rise time and 50 MHz bandwidth suggest a practical focus on power troubleshooting rather than advanced high-speed signal integrity work. If your main need is waveform visibility on high-voltage power circuits, it is likely sufficient; if you need detailed fast-edge fidelity, it may be limiting.
Q: Can this replace a battery-powered handheld oscilloscope for mains or high-voltage work?
A: Not really. It solves a different problem. This probe lets you use a standard grounded oscilloscope to measure differential high-voltage signals more appropriately, while a battery-powered handheld scope changes the isolation setup of the instrument itself. If you already own a bench scope and need better high-side or floating measurements, a differential probe is the more direct upgrade. If you need maximum portability or field isolation, a handheld scope may still be the better tool.
