The DP6020B, DP6040B, and DP6060B probes are low-voltage differential probes with floating measurement capability. They have measurement voltages of ±20V (DC+Pk), ±40V (DC+Pk), and ±60V (DC+Pk) respectively, with a bandwidth of up to 1GHz. They offer attenuation settings of 10:1, 20:1, and 50:1, feature input impedances of 200KΩ and 400KΩ, and a low input capacitance of 1pF, which can minimize circuit loading to the greatest extent. Equipped with an overvoltage alarm function, they are compatible with any oscilloscope with a 50Ω BNC input and can be powered via the USB port on the oscilloscope or computer. Widely used in various applications, they can provide excellent general-purpose differential signal measurement for today's high-speed power measurement, in-vehicle bus measurement, and digital system design.
