Tektronix P7508 TriMode Probe, 8 GHz, TekConnect, ±15 V Limit

Description

Eight gigahertz is plenty for a large share of digital and embedded debug. The Tektronix P7508 TriMode probe brings that bandwidth on a TekConnect interface. It is the entry step of our 75-series list, below the P7513A at more than 13 GHz and the P7516 at 16 GHz. As a TriMode design, this active differential probe can also show single-ended and common-mode signals without moving the tip. Lost in HCM rents and sells it, plus it arranges service on request.

Jobs that fit 8 GHz

• Debug of DDR-class buses and fast GPIO on embedded boards.
• Clock and reset checks during board bring-up.
• Signal studies on industrial controllers and automotive electronics.
• Teaching labs that show real differential behavior.

In each case, the probe should match or exceed the needs of the signal, while the scope sets the final ceiling. For example, an 8 GHz probe on a much faster scope leaves scope bandwidth unused. In that case, the P7513A or P7516 may suit you better.

Specs for the Tektronix P7508 TriMode probe

The listing gives 8 GHz bandwidth and a 100 kΩ differential input resistance. It also lists 5X or 12.5X attenuation. The maximum nondestructive differential input is ±15 V. Finally, the interface is TekConnect.

Before you connect

Check that your oscilloscope has a TekConnect input, because the probe needs one. Next, plan the tips and adapters for your board, since they affect the result. Then keep each signal well inside the ±15 V limit, and follow the manufacturer’s manual and ratings.

Why rent first

Many teams rent this probe when a new product enters the line or a field issue appears. After that, they decide whether to buy one for daily use. So request a quote from Lost in HCM for either option. Include the scope model, signal level and tip needs. You can also view all oscilloscope probes, check Tektronix for documents, or contact SMK Vietnam with questions.

FAQ on the P7508

Is 8 GHz the lowest bandwidth in this group?

Yes. Of the three 75-series probes we list, the P7508 has the lowest bandwidth.

Does it share specs with the P7516?

Apart from bandwidth, the listed input resistance, attenuation, limit and interface match.

Can the Tektronix P7508 TriMode probe work without TekConnect?

The listing only names TekConnect, so ask Lost in HCM about your scope.
