RIGOL PHA1150 PHA Series High-Voltage Differential Probe

The PHA series high-voltage differential probe connects to the voltage under test through the high-voltage differential input cable to convert the input high voltage into the low voltage, and then display the waveforms on the waveform measuring instrument by connecting its output interface to the waveform measuring instrument.

• High bandwidth to meet the requirements of most high-frequency test system
• PHA0150: 70 MHz
• PHA1150: 100 MHz
• Diversified ranges and two attenuations to meet the requirements for most common-mode test circuit
• 50X: 150 V (DC + peak AC)
• 500X: 1500 V (DC + peak AC)
• 5 MHz bandwidth limit(see note)
• For the low-frequency signal measurement, this function can reduce the noise and interference of high-frequency signals to meet the measurement requirement for the switching frequency of most switching transistors (FETs) in the switching power supply.
• Note: 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.
• High-voltage differential input mode
• Higher input impedance and lower input capacitive on the input terminal ensure accurate and fast measurement
• Sound common-mode noise rejection
• Standard BNC output terminal, compatible with the waveform measuring instruments of most manufacturers.
• Audible alarm beeper and visible indicator blinking for sounding the alarm; the alarm can be disabled manually
• Auto memory function, capable of automatically saving the working status that was set before it is shutdown
