DF-600 High Bandwidth High Voltage Active Differential Probe

clips

A lot of money will be spent if both a differential probe and an active probe are needed.  If a conventional differential probe is used as an active probe, there will be a big problem when there is a big voltage difference between the target ground and the oscilloscope ground.  This DF-600 Differential Active Probe has a switch to select differential or single-ended mode and another switch to change the measured voltage range.

The DF-600 Differential Active Probe is a high input impedance and low input capacitance probe.  It also supports extremely high frequency bandwidth, and high voltage input.  It is designed using three OP amps, namely two FET buffer OP amps and a low offset OP amp. Therefore, even with long-term operations, the measured voltage will not drift.  The voltage offset always approach 0 volts. (USB power supply should be 5V ±2%). The following diagram shows the circuit of DF-600.


clips

A wide assortment of connectors, wires and clips come with the DF-600 for different connection scenarios and situations.  Also a 50 Ω pass through BNC connector is provided for high impendance oscilloscope inputs, as well as a USB power input cable.
