Purpose and user

The Pintech PT-5102 is a high-frequency differential probe designed for oscilloscope measurements up to 150MHz bandwidth. It suits engineers and technicians who need to capture fast rise times of 2.3ns on floating or differential signals within an 80V peak-to-peak range.

Sustained measurement behaviour

The probe maintains ±2% typical accuracy across two attenuation settings: 2X and 20X. Input impedance presents 1MΩ paralleled with 7.5pF differentially and 0.5MΩ with 15pF single-ended to ground. Common-mode rejection exceeds 80dB at 60Hz, 60dB at 100Hz and 50dB at 1MHz, while noise stays at 1mV rms.

Installation and common issues

A standard BNC interface connects directly to any oscilloscope with a 50Ω input, and the package includes a dedicated input cable, adapter, two probe hooks, two alligator clips and a manual. The 220×85×30 mm body weighs 450g, so cable strain relief matters. Users sometimes forget to match the attenuation selector on the probe to the oscilloscope channel setting, which causes scaling errors.

Questions about this item

How much noise does the PT-5102 add when it runs continuously at 150 MHz bandwidth?

The probe specifies 1 mV rms of noise across its DC-150 MHz range, so long sessions do not increase that figure.

What oscilloscope input impedance is required for the PT-5102 BNC output to meet its ±2 % accuracy?

The probe is calibrated for a 50 M scope input; using a different impedance will shift the attenuation ratio and accuracy.

Can the PT-5102 connect directly to an older oscilloscope that only has a 1 M input and no 50 Ω setting?

The probe expects a 50 M oscilloscope input; a 1 M input will alter the attenuation and accuracy, so a 50 Ω feed-through adapter is recommended.
