Description
About the DP-60HS Oscilloscope Differential Voltage Probe
The DP‑60HS differential voltage probe for small signal applications is an important accessory for any application involving low‑level ‘non‑ground‑referenced’ or floating signals. These probes allow isolated and floating measurements with any digital oscilloscope or computer‑interface DAQ, allowing the oscilloscope to remain safely grounded.
Using a DP‑60HS differential probe, floating (isolated) measurements can be made on a variety of control signals and audio signals found in power amplifiers and instrumentation systems. The isolated input is made via two 4 mm safety banana sockets, ensuring safe connection to floating circuits. The BNC output provides a clean, ground‑referenced signal for easy connection to an oscilloscope or DAQ. The DP‑60HS isolation probes are powered from a battery or external power supply, enabling both portable and bench‑top operation.
