PHA High-Voltage Differential Probe
The PHA series high-voltage differential probe (hereinafter referred to as PHA
series 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.
Main Features
High bandwidth to meet the requirements of most high-frequency test
system
PHA0150: 70 MHz;
PHA1150: 100 MHz;
PHA2150: 200MHz
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
[1]
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.
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;
