A single-ended oscilloscope input can be transformed into a balanced differential input using this probe, boosting ability to capture high speed signals at low voltages
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 supply, which is available independently but is fitted 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.
