SIGLENT SDP6150D High Voltage Differential Probe
The SIGLENT SDP6150D is a professional 400 MHz high voltage differential probe for accurate measurement of fast floating high voltage signals with compatible SIGLENT oscilloscopes. It is especially suitable for advanced power electronics, high-speed switching applications, inverters, frequency converters, motor drives, switching power supplies and other electrical power systems.
The SDP6150D supports differential voltage measurements up to ±1500 V DC + peak AC and uses 100X / 1000X attenuation. The 100X range is suitable for measurements up to ±150 V, while the 1000X range is used for measurements up to ±1500 V. This allows the probe to handle both medium and high voltage differential signals while maintaining excellent measurement flexibility.
With 400 MHz bandwidth and a fast ≤1 ns rise time, the SDP6150D is well suited for capturing fast switching edges and high-speed transient signals. It offers ±2% DC accuracy, high input impedance and low input capacitance. Typical CMRR is specified at 80 dB at DC, 60 dB at 100 kHz and 40 dB at 1 MHz, helping to reduce the effect of common mode noise. A selectable 5 MHz bandwidth limit is also available for cleaner low-frequency measurements.
The SDP6150D includes a visual overrange indicator and a switchable audible overrange alarm to help protect the probe during measurements. Zero adjustment is supported manually and can also be controlled through compatible SIGLENT oscilloscopes.
The SDP6150D uses SIGLENT’s SAPBUS interface, which provides power, communication and automatic probe recognition. It is compatible with SIGLENT SDS3000X HD, SDS6000X and SDS7000X oscilloscopes. The probe is supplied with a high voltage rated accessory kit including alligator clips, test bars, hook clips, Y-shaped clamps and extender leads.
