Description
A long reach and a strong divider make the Tektronix P5100A high-voltage probe a practical choice for big enclosures. In fact, it is a passive, single-ended probe with 100X attenuation and 500 MHz bandwidth. Plus, its 2 m nominal cable lets the scope stay well back from the panel you probe. Lost in HCM offers it for rental or sale, and arranges service on request.
What 100X does for you
The probe divides the input by 100 before it reaches the scope. As a result, high signal levels land inside the normal range of a standard input. Remember to set the scope to 100X, unless the instrument reads the probe coding itself. Readout coding works on supported instruments, according to the listing.
Compensation across many scopes
Unlike probes that compensate on their own, this one has a manual compensation range of 7 to 30 pF. In other words, you can trim it to suit any scope input whose capacitance falls inside that span. So the P5100A can serve a mixed fleet of older and newer oscilloscopes. Then follow the manufacturer’s procedure whenever you compensate it.
Data from the listing
- Bandwidth: 500 MHz.
- Attenuation: 100X.
- Input loading: 40 MΩ with 2.5 pF.
- Cable length: 2 m nominal.
- Voltage rating: 2.5 kV peak and 1000 V RMS CAT II, subject to frequency derating.
- Connection: single-ended, for ground-referenced signals.
Keep in mind that pulse duration is a separate constraint from the headline rating. Follow the manufacturer’s manual and ratings.
Jobs for the Tektronix P5100A high-voltage probe
Maintenance teams often probe drive cabinets, switchgear panels and test rigs where the scope cannot sit close. In those spots, the longer cable helps. Likewise, labs with several scope brands or ages value the wide compensation range. For a single site survey, a rental keeps costs tied to the job.

P5100A buyer FAQ
Why choose it over the TPP0850?
Pick it for the longer cable, the 100X ratio and manual compensation. The TPP0850, by contrast, offers 800 MHz and 50X.
Is the 1000 V figure valid at all frequencies?
No. According to the listing, the rating is subject to frequency derating, so check the data sheet.
Which accessories come with the Tektronix P5100A high-voltage probe?
The photo shows a reference set. So ask Lost in HCM to confirm the contents of your unit.
