Tektronix TPP0250 Passive Probe, 250 MHz, 10X, Under 4 pF, TekVPI, 1.3 m

Description

Plenty of bench work never needs more than a few hundred megahertz. The Tektronix TPP0250 passive probe covers that ground at 250 MHz with 10X attenuation. It is a passive, single-ended voltage probe that joins the scope through TekVPI, and it keeps input capacitance below 4 pF. Lost in HCM supplies it in Vietnam for purchase or project rental, and it arranges service on request.

Low loading at 250 MHz

This probe lists the same 10 MΩ input and under 4 pF that the faster TPP0500B and TPP1000 list. So sensor lines, PWM outputs, serial buses and reset circuits see little extra load. In practice, the waveform on screen stays close to what the circuit does without the probe attached.

Key data

• Kind: passive, single-ended voltage probe.
• Bandwidth: 250 MHz.
• Attenuation: 10X.
• Input resistance: 10 MΩ.
• Input capacitance: below 4 pF.
• Cable: 1.3 m.
• Connection: TekVPI.

Fitting the Tektronix TPP0250 passive probe into your lab

First, check the scope. The listing names a TekVPI interface, so the oscilloscope needs a supported TekVPI input. For scopes with BNC inputs, the TPP0100 listing names a BNC interface instead. Next, think about speed. A 250 MHz probe suits control boards, power-stage timing and slower digital work, while fast clocks and high-speed buses call for the TPP0500B or TPP1000. Then compensate the probe, set 10X on the channel and keep the ground short.

Spare sets for teaching and production

Training rooms, repair benches and production test stations often need several matching probes. Because a tip can bend or break, a few spares also keep a station running. For a short course or a line trial, a rental from Lost in HCM can cover the peak, while a permanent station usually justifies a purchase. Tell them your scope model and accessory needs, then get a TPP0250 quote from Lost in HCM. In addition, you can view all oscilloscope probes on SMK, visit tek.com, or contact SMK Vietnam.

Tektronix TPP0250 passive probe questions

Is 250 MHz enough for my board?

For many control and power jobs, it is. However, if fast edges look rounded, try the TPP0500B or TPP1000 and compare the result.

What separates it from the faster TPP models?

Bandwidth alone, going by the listings. The TPP0500B reaches 500 MHz and the TPP1000 reaches 1 GHz, while attenuation, input, cable and interface stay the same.

Can I order several at once?

Yes. Tell Lost in HCM how many probes you need and which scopes they will serve, so the quote covers the full set.
