Safety Precautions
CAUTION
Beware of high voltages to avoid electric shock. Understand the maximum
input voltage for the probe.
Do not operate in wet conditions or in an explosive atmosphere.
Before use, please check whether the exterior of the probe is damaged. If
damaged, stop using it.
Turn off the circuit under test before connecting it to the probe.
When connecting the BNC output cable of the probe to the oscilloscope or
other devices, ensure that the BNC terminal is safely grounded.
After measurement, turn off the circuit first and then remove the probe.

General Inspection
1 Inspect the packaging
RIGOL has carried out strict inspections on each product before leaving
the factory. When you receive the product, please check whether the
packaging is intact. If the packaging has been damaged, do not dispose
the damaged packaging or cushioning materials until the shipment has
been checked for completeness and the probe has passed both electrical
and mechanical tests.
The consigner or carrier shall be liable for the damage to the instrument
resulting from shipment. RIGOL would not be responsible for free
maintenance/rework or replacement of the instrument.
2 Check the probe
In case of any mechanical damage, missing parts, or failure in passing the
electrical and mechanical tests, contact your RIGOL sales representative.
3 Check the accessories
Please check the accessories according to Appendix 2 Package List in
this manual. If the accessories are damaged or incomplete, please contact
your RIGOL sales representative.

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;

PHA User Guide 3
the alarm can be disabled manually
Auto memory function, capable of automatically saving the working status
that was set before it is shutdown
Note[1]:
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
Floating voltage

Strong current or high voltage
isolation measurement
Switching power supply

Power conversion and other
related designs
