When plugging in, make sure that the active probe amplifier is tightly connected to the probe head via the connection points. Pay attention to the spring direction, if connected in the wrong direction, the performance of the active probe will be undermined, and even worse, the probe may be damaged.
CAUTION
There is a black mark sleeve on the negative pole of the soldering single- ended probe head.
Probe Head
PVA8000 supports a hand-held probe head and a solder-in probe head.
Hand-held Probe Head
The types of hand-held probe heads include hand-held differential probe heads and hand-held single-ended probe heads.
Like using common passive probes, you can use this kind of probe head to easily measure signals. Besides, the spacing between the probe tips can be easily adjusted to fulfill your various measurement requirements.
For the hand-held differential probe head, the spacing between the probe tips is controlled by the roller on the probe head. As shown in Figure 3, turning the roller forwards or backward can precisely adjust the spacing between the two probe tips.

As shown in Figure 4, the probe tip is a standard accessory and replaceable.
If it is damaged during use, you can easily replace it with a new one (refer to To Replace Probe Accessories).

For hand-held single-ended probe heads, rotating the ground pin can adjust the spacing between the ground pin and probe tip, as shown in Figure 5.

The signal pin and the ground pin are standard accessories. There are different types of signal pins and ground pins, and they are replaceable. You can use them according to different application scenarios (refer to To Replace Probe Accessories).
PVA8000 series probe provides three types of signal pins and four types of ground pins to cater to different test requirements. The structure of the pins is shown in Figure 6. Different types of signal pins and ground pins can work with each other in different combination forms.
Signal Pin Types
a) Signal Pin (bent): (same as the hand-held differential probe tip, available to use for any hand-held differential probe): suitable for carrying out the handheld spot test for near-distance test points.
b) Signal Pin (straight): suitable for the hand-held spot test for near- distance test points.
c) Signal Adapter (square pin): work with Male Dupont wires, suitable for measurements of a longer distance of test points; or work with square pin ground adapter, suitable for in-line circuit board pin tests. Ground Pin Types
d) Ground Pin (pogo): suitable for the hand-held spot test for near-distance test points.
e) Ground Pin (solderable): suitable for the hand-held spot test for a longer distance of test points or soldering test.
f) Ground Adapter (square pin): work with the signal square pin adapter, suitable for in-line circuit board pin tests.
g) Ground Adapter (angled): works with male DuPont wires for measurements of a longer distance of test points.

Solder-in Probe Head
The solder-in probe head includes two types: solder-in differential probe head and solder-in single-ended probe head, as shown in Figure 7 and Figure 8. Wherein, the solder-in probe head is suitable for the measurement of high- density IC pin signals.

The hand-held differential probe head can be used to measure differential and single-ended signals. Button 1, 2, and 3 on the probe head has the memory function. Take Button 1 as an example. When you need to save the current position of the probe head for future use, long press this button in this position until the indicator between the probe tips blinks. Then release the button. In this way, the position of the probe tip is remembered by the probe. For future use, once you want to adjust the probe to this specified
position, just press Button 1, and then the probe tip will be adjusted automatically to this position. The button is a button for controlling the on/off status of the indicator located between the probe tips. In the weak light environment, you’d better turn on the indicator to make measurements clear to see.
The following figure shows the operation demonstration:

Note: If the length of the nickel wire is longer than 4 mm, the bandwidth specification of the probe will be affected. You can use the trim gauge to measure and cut the nickel wire.
To Adjust Offset Voltage
RIGOL DS70000 series oscilloscope can provide offset voltage to the PVA8000 series active probe. Then the offset voltage can be output through the BNC module of the robe. The offset voltage adjusts the measured signal which exceeds the input dynamic range of the probe to within an appropriate range to ensure the measured signal’s integrity. You can adjust the offset voltage by operating the front panel menu of the oscilloscope. The operation method is as shown below.

1. Follow the instructions in To Connect to the Oscilloscope to connect the PVA8000 series active probe to the channel input terminal (e.g. CH1) of the DS70000 oscilloscope.
2. Open the probe offset voltage control menu of the DS70000 oscilloscope (CH1 Probe Bias) and input the value with the virtual keypad.

To Calibrate the Probe
Before using, you should calibrate the PVA8000 series active probe. Follow the procedures below to calibrate the PVA8000 active probe:

1. Connect the PVA8000 active probe to the analog channel (CH1 to CH4 of the oscilloscope, illustrations here are based on CH1).
2. Open the probe calibration control menu (front panel operation: CH1Probe Calibration), and the oscilloscope starts to calibrate the probe. The calibration will last for about 80 to 90 seconds. When the probe calibration is finished, a prompt message “Probe calibration finished!” or “Probe calibration failure!” is displayed in the user interface of the oscilloscope. As the offset voltage of the PVA8000 series active probe is provided by the BNC module, after the first calibration, you do not need to calibrate it again before use next time.

Note: Technical specifications of the PVA8000 series active probe depend on the calibration operation. After the calibration is finished, the DC gain, offset voltage zero and offset gain will be calibrated. After inserting the probe, users can view the information about the vendor, model, serial number, and the last calibration time of the probe through the menu operation: CH1  Probe.
