Equivalent-time sampling can limit or avoid any interpolation since the equivalent (virtual) acquisition rate is not limited by the digitizer sample rate and can be huge. This advantage has its price: ...

Equivalent-time sampling oscilloscopes generally provide higher bandwidth for the money, but they sample slowly and are thus limited to repetitive waveforms. The PicoScope 9404-05 sampler-extended ...

For reference: the 5GHz and 16GHz models (PicoScope 9400 types) are more traditional real-time scopes that rely on ‘random equivalent time’ sampling. They sample at 12bit ADC resolution and at ...
