Overview
RSDPB5000 series high voltage differential probes are designed for the
measurement of high voltage differential signal, to meet the demand for floating
measurement. The bandwidth can be as high as 100MHz, meeting the demand for
majority of measurement systems.
There are a variety of ranges to choose from, and their differential voltage
measurement range can meet with the demand for majority of tested circuits. Users may
go into test mode to adjust the offset voltage, and also to adjust automatically to
prevent probes being disordered after years’ of use. The electronic touch buttons give
them a longer working life.
The function of 5MHz bandwidth limit selection, whose frequency bandwidth fits
the FETs switching frequency measurement in most switching power supplies, and they
can filter out higher frequency noise and interference. With the sound & light alarming
function, this can also be closed manually, with a USB power supply connector to make
it easier and more flexible for use. The probes are equipped with standard BNC input
connectors, they can be used with any manufacturer oscilloscope ( oscilloscope input
impedance should set to 1MΩ. when 50Ω is selected, the attenuation multiply
attenuates double.) to test waveform of the tested circuits, there is an automatic save
function, to prevent users re-operating in case of power supply drops. The probes have
good capability of common mode noise suppression and can be widely used in the
research and development, debugging or overhauling work for switching power supply,
frequency converter, electronic ballast, frequency conversion electronic appliances and
other electric power equipments.

Operating the Probe Safely
1. Youshould estimate the tested voltage amplitude before testing, please do not use if
exceeds the voltage range, because it is likely the probe is damaged.
2. Connect the input lead and output lead to the probe, and then connect the probe to the
oscilloscope or other instruments.
3. Connect the power adapter to voltage probe, the power indicator light turns on green.
Please select proper range based on the tested voltage. When the tested voltage exceeds range,
the overload indicator light is on with alarming sound, which can be manually turned off.
4. Please set proper attenuation rate for the oscilloscope or other instruments according to
the probe range. And adjust the oscilloscope sensitivity based on the tested voltage.
5. Connect the probe clips based on needs, start after connecting to the circuits to be tested.
When testing, the probe body should be kept away from high voltage pulse circuits to reduce
interference to the probe.
Test Mode (Offset Setting)
Users may enter the test mode to adjust offset based on needs. The probes may be disordered
after years’ of use. The adjustment method is as follows if not at zero:
①Please press these two keys, and make short circuits for input terminals.
②Turn power on to start, entering test mode, and the overload indicator light is on,
release the two keys.
③Go into the high attenuation fact or offset adjustments under the state, press the
offset increase. Press offset decrease.
④After the adjustment, press key to switch to low attenuation ratio offset adjustment,
press key offset increases, press , offset decreases.
⑤Then press key to exit the test mode, offset adjustment is completed and the
overload indicator light is off, entering into normal operation mode.
Safety Notices
1. Please try to wind up the input leads when testing, this is better for eliminating noise and
to improve the ability of high frequency response. Please view below for the winding method:

11
2. It is better not to extend input lead when testing; otherwise it may introduce
more noise. If extra extension lead is necessary, please ensure the extension leads are
the same length, and the input frequency is under 10MHz, errors may exist if exceeds
10MHzoutput.

Overview
The RSPDB4080 differential probe provides a safety means for measuring differential
voltage to all models of oscilloscopes. It can convert the high differential voltage (≤800Vpeak)
into a low voltage (≤8V) and display this on the oscilloscope. Its bandwidth is up to 50MHz,
which is ideal for large power testing, development and maintenance.
The RDPB4080 is designed to operate with the 1MΩ impedance oscilloscopes. When
combined with the 50Ω load, the attenuation will be 2 times as much.
RDPB4080 is recommend for use with our own manufactured PL-10 to expand the
measuring with the electricity meter to observe more accurate measurement. The accuracy of
oscilloscope is 1% and the electricity meter is about10%.
