1. Introduction
OP6031/OP6032 is the latest optical isolated voltage probe with remarkably high CMRR. The
CMRR of traditional differential probe decreases fast in high-frequency range, as a result, measuring the
small voltage signal waveform (e.g., the driving voltage when measuring the upper MOSFET of the
half-bridge circuit) under high CM interference voltage accurately become a extremely hard task.
OP6031/6032 applies optical isolation technologies and gains remarkably high CMRR in all working
bandwidth, helping our customers to deal with these kinds of challenging measurement with low cost.
Product Characteristics:
Bandwidth over 200MHz
Isolation voltage over 60kV
High CMRR
High precision in wide temperature range
Double range design with measurable differential voltage of 30V/3V
Able to measure gate voltage drive of Si/SiC/GaN and other power devices
Able to measure high-frequency current of Si/SiC/GaN and other power devices with coaxial
shunt CSD series.
2 Chargeable batteries that can be replaced to keep the probe work continuously
2. Application
OP6000 series can be widely applied in the R&D, debugging or maintenance of switching power
supply, motor driver, new energy inverter, converter, LED power supply, household appliances and other
electrical power devices.
Floating signal test
The gate driving signal measurement of upper bridge MOSFET can also be applied to the
measurement of high-speed driving waveform of SiC and GaN.
Small signal measurement of differential mode under high common mode voltage

1Input connector: USB connector used to connect standard attenuator of 2X or 20X. Please
select the corresponding attenuator according to need.
2BATTERY indicator: lighted green under normal condition; lighted yellow under insufficient
power supply, please change the battery in time.
3TEC indicator: temperature control indicator of the laser. Lighted green under normal condition,
and lighted red when temperature control system malfunctioned.
4Front-end light emitter switch: power supply switch. Please turn it off when not needed.
5Optical fiber: connecting the front-end light emitter and rear-end light receiver, 1.4m in length.
Please refer to the tips below when using:
Do not put heavy objects on the optical fiber to avoid any stress on it.
Do not squeeze or curl the optical fiber and do not curl the optical fiber into a loop
diameter less than 10cm.
Do not twist or knot on optical fiber and do not pull it hard.
Do not drop the E/O transmitter and O/E receiver, as the impact will possibly damage
the inner optical components.
Do not drop heavy objects like chairs or wheels on the optical fiber as they could
possibly damage it.
Please put the optical isolated probe back to its suitcase as delivered.
Check the optical fiber carefully before use, if there is any damage please stops using
immediately.
For better precision, please begin testing after a warm-up of 3~5 minutes.
6Power supply connector: rear-end O/E receiver DC 5V power supply connector.
7Auto-zero button: realizing auto-zero set of the output signal.
8Auto-zero indicator: lighted when auto-zero setting and the light goes off after two clicks,
indicating that zero set is successful; If the indicator light is still on and the buzzer sounds for
one second after zero set, zero set has failed.
9Laser indicator: lighted green indicates that front laser device is okay.
10 Power indicator: O/E receiver power indicator.
11 Output connector: standard BNC output connector, connected with standard BNC cable to the
oscilloscope.
█ Attenuator

1Attenuator: the attenuator will connect the USB socket of the probe and SSMB RF female
socket of the circuit under test. Attenuator have different models with ratio of 20X or 2X,
corresponding with range between ±30V / 3V.The standard configuration is 20X. Users can
choose proper attenuator according to the signal under test and set the attenuation parameter
on oscilloscope.
2SSMB male socket: to gain higher CMRR, users can directly weld the socket to the component
or the circuit board of the device under test. The closer SSMB male socket is welded to the
connecting line of the component, the higher CMRR will be.
3SSMB Male socket to DuPont connector: easy to use in the case of low requirements for
CMRR.
█ Battery
The product is equipped with two 7.4V/950mAh lithium batteries as standard, as shown in the figure
above: battery installation position. In this design, after inserting the attenuator, the attenuator plays a
limiting role, and the battery cannot be removed. If you need to remove the battery for charging, refer to
the following steps:

6. Operating Process
User need to estimate the range of voltage under test and plug-in the proper attenuator before
operating. Turn on the E/O transmitter and confirm the indicator light signal.
Connect the 5V power supply to the rear-end O/E receiver, confirm the indicator light signal of the
rear-end box. The rear-end starts functioning.
Connect the BNC signal cable between rear-end of the probe and oscilloscope, setup attenuation
ratio according to the plug. Adjust the sensitivity of the oscilloscope according to voltage under test.
Connect the SSMB plug of the attenuator with the SSMB socket of the circuit under test.
Turn on the power supply of the circuit under test and begin testing.
Put the front-end box of the probe overhead if possible to decrease the interference from
high-voltage pulse circuit.
Because the front-end of the probe is directly connected with the high voltage of the circuit under
test, please switch off the power supply of the circuit under test first before touching the probe.
To save the battery power, turn off the switch when you don’t need it.
Please charge in time if the power indicator of the front-end box turns yellow.
The typical connection diagram is shown below:
