:
When the bandwidth is limited to 5 MHz, the internal output circuit of the PHA
series probe is connected to a 5 MHz low-pass network. The low-pass network
can reduce the high-frequency components, the noise, and the harmonics,
which is conducive to the testing and analysis of the low-frequency signals.
Measurement Scenarios
The PHA series probe is mainly used in scenarios where high-voltage floating
measurement is required, such as
