SIGLENT SDP6150A 100MHz High Voltage Differential Probe
The SIGLENT SDP6150A is a 100 MHz high voltage differential probe for safe and accurate measurement of floating and high voltage signals up to ±1500 V. With 50X/500X attenuation, high input impedance, low input capacitance, overrange indication and SAPBUS integration for compatible SIGLENT oscilloscopes, it is ideal for power electronics, inverter, motor drive and switching power supply measurements.
SIGLENT SDP6150A High Voltage Differential Probe
The SIGLENT SDP6150A is a professional 100 MHz high voltage differential probe designed for safe, precise and reliable measurement of floating high voltage signals with compatible SIGLENT oscilloscopes. It is ideal for engineers working on power electronics, switching power supplies, frequency converters, motor drives, electronic ballasts, variable frequency household appliances, inverters and other electrical power devices.
The SDP6150A supports differential voltage measurements up to ±1500 V DC + peak AC and uses 50X / 500X attenuation. The 50X range is suitable for measurements up to ±150 V, while the 500X range is used for measurements up to ±1500 V. This makes the probe flexible for both lower and higher voltage differential measurements.
The probe offers 100 MHz bandwidth, ≤3.5 ns rise time, ±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 suppress common mode signals during differential measurements. A selectable 5 MHz bandwidth limit is available to reduce high frequency noise when measuring lower frequency signals.
For safety and convenience, the SDP6150A includes a visual overrange indicator and a switchable audible overrange alarm. Zero adjustment is supported manually and can also be performed through the oscilloscope when used with compatible SIGLENT models.
The SDP6150A uses SIGLENT’s SAPBUS interface, providing probe power, communication and automatic recognition on compatible SIGLENT oscilloscopes such as the SDS3000X HD, SDS6000X and SDS7000X series. The probe includes a practical accessory kit with high voltage rated accessories such as alligator clips, test bars, hook clips, Y-shaped clamps and extender leads.
