Differential probe boasts 500MHz bandwidth

A novel differential probe can transform a single-ended oscilloscope input into a balanced differential input with a bandwidth of 500MHz and very high common-mode rejection.

The new 701920 differential probe from Yokogawa Martron is capable of transforming a single-ended oscilloscope input into a balanced differential input with a bandwidth of 500MHz and very high common-mode rejection (typical CMPR is 60dB).

The probe is designed to overcome the limitations of traditional single-ended inputs in accurately capturing high-speed signals at low power-supply voltages, particularly when isolated probing is required to capture noise-resistant differential signals in leading-edge designs.

A differential probe is also particularly useful when creating a trigger which cannot usually be generated from a calculated signal in single-ended oscilloscopes.

The probe is powered with a +/-12V signal, which can be supplied independently but is available as standard on the latest oscilloscopes in the Yokogawa range.

The 701920 has a frequency bandwidth of DC-500MHz, an input reactance of 100kW and an input capacitance of 2.5pF (both relative to ground).

External dimensions are only 111 x 22 x 14 mm.

A wide range of probe tips is available.
