The 300MHz HT300B are high impedance probes with switchable attenuation ratio (1:1 and 10:1).
This oscilloscope probes are compatible with hantek digital storage oscilloscopes or similar oscilloscopes with 1 M ohm BNC input.
These passive probes have been designed and calibrated for use with instruments having an input impedance of 1M Ω paralleled by 20pF. However, these may be recalibrated for use with instruments having an input capacitance of 15 to 40pF.
NOTE: The BNC connector of these probes has a pin hole without a pin. This is as per the design and does not indicate any damage or fault in the probe.
