The high-voltage differential probes of the DP series are based on Micsig's innovative SigOFITTM technology. They are characterised by a very low noise floor, excellent amplitude-frequency characteristics and industry-leading common mode rejection, enabling users to test high frequency and high voltage signals with ease. Micsig DP series probes can be used with oscilloscopes from all manufacturers.
Features
- 5 MHz bandwidth limitation: When measuring the FET switching frequency in most switching power supplies, the DP probe effectively eliminates high-frequency noise.
- Quick Zero: Short-circuit the test leads, press the zero button, the probe can be zeroed very quickly.
- Dual range selection: Improves the signal-to-noise ratio, meets more test requirements.
- BNC interface: Standard BNC interface, works with any oscilloscope.
- USB power supply: Powered directly from the oscilloscope's USB port via a Type-C cable.
- Overvoltage alarm: LED flashes, buzzer "beeps" quickly and indicates an over-range alert.
- Exceptionally compact: Much smaller than conventional differential probes.
