Probe Introduction
PVA7000, with more than 2.5GHz bandwidth, is an active probe for high
frequency application. It can be used to measure differential and single-ended
signals with better common mode rejection. PVA7000 uses plug-on socket
probe head and supports 3 types of interchangeable probe heads to optimize
the performance and usability. Besides, its replaceable probe tip prolongs the
service life of the probe and the probe tip spacing can be precisely adjusted to
fit different test point spacings.
PVA7000 is compatible with the auto-identification port of RIGOL
MSO/DS7000/MSO8000 series oscilloscope and can be recognized and
configured automatically by this port. Its snap-in BNC connector enables easier
connection with the oscilloscope.
PVA7000 provides various accessories and options, as well as multiple
replaceable components which make it applicable to be used in different tests
and measurements.

connected to the desired probe head.
Figure 2 Active Probe Amplifier
When connecting a probe head to an active probe amplifier, push it
straight in. For single-ended probe, when connecting them, pay attention to
their polarities. If the polarity is reversed, the performance of the active probe
would be undermined and the active probe might even be damaged.
CAUTION
There are black mark sleeve on the negative pole of the solder-in
single-ended probe head.

The type of Hand-held probe head is: hand-held differential probe head.
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 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 backwards can precisely adjust the spacing between the two
probe tips.
Figure 3 Hand-held Differential Probe Head
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).

2. 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 5 and
Figure 6. Wherein, solder-in differential probe head is suitable for
measurement of high-density IC pin signals.
Figure 5 Solder-in Differential Probe Head
Figure 6 Solder-in Single-ended Probe Head
When using the solder-in probe head for measurement, please use an auxiliary
device to fix the probe head. Do not use your hand to fix the probe head, or
else, the lead resistor soldered onto the probe head might break or fall off.
What’s more, the hand-held position might also affect the probe performance.
The nickel wire of the solder-in probe head is a standard accessory. If the nickel
wire under use is damaged or broken, please replace it with an appropriate lead
resistor (refer to To Replace Probe Accessories).

To Connect to the Oscilloscope
After PVA7000 is connected correctly to a RIGOL MSO8000 series oscilloscope,
the oscilloscope recognizes the probe automatically and provides both power
and offset voltage to the probe. You can adjust the offset voltage (refer to To
Adjust Offset Voltage) and calibrate the probe (refer to To Calibrate the
Probe) by the front panel menu of the oscilloscope.
Please connect the probe to the oscilloscope following the steps below:
1. Connect the probe head (in the figure, taking a hand-held differential
probe head for example) with the active probe amplifier. If a single-ended
probe head is used, during the connection, pay attention to their polarities.
2. Connect the other end of the active probe amplifier to the channel input
connector of the oscilloscope and make sure the connection is tight.
3. Use any probe auxiliary device to connect the probe to the circuit to be
tested.

4. To disconnect the probe from the oscilloscope, press the button on the
probe (as shown in the left figure below), pull the connector straight out of
the oscilloscope (as shown in the right figure below) and then release the
button.
CAUTION
Do not twist the probe on the BNC connector of the oscilloscope.
Otherwise, the probe might be damaged.

To Use the Probe Head
In the Probe Head section, PVA7000 can be connected with 3 kinds of probe
heads. You can easily change the probe head by using the method introduced
in To Replace Probe Accessories. This chapter introduces how to use these
three kinds of probe heads respectively.
1. Hand-held Differential Probe Head
The hand-held differential probe head provides an effective bandwidth of more
than 2.5 GHz. The spacing between the two probe tips can be precisely
adjusted by turning the roller. The probe tips are replaceable, which can
prolong the service life of the probe.
The hand-held differential probe head can be used to measure differential and
single-ended signals. During the measurement, you can turn the roller on the
probe head to adjust the spacing between the probe tips so as to fit
measurements with different spacing requirements.
The structure of the hand-held differential probe head is shown in Figure 7.

③ 50Ω probe tip.
2. Solder-in Differential Probe Head
The solder-in differential probe head provides an effective bandwidth of more
than 2.5 GHz. The replacement of the nickel wire enhances the usability of the
probe and prolongs its service life.
The structure of the solder-in differential probe head is shown in Figure 8.

② 0.2mm Nickel Wire.
When the points to be tested are widely spaced, the length of the nickel wire

3. Solder-in Single-ended Probe Head
The solder-in single-ended probe head provides an effective bandwidth of more
than 2.5 GHz. The replacement of the nickel wire enhances the usability of the
probe and prolongs its service life.
The structure of the solder-in single-ended probe head is shown in Figure 9.
The pin at the same side with the negative pole mark sleeve (refer to Figure 6)
is negative.

To Replace Probe Accessories
1. To replace the probe head
Take care not to damage the connecting part to avoid affecting the probe
performance when replacing the probe head.
Replacing Method:
① Disconnect the current probe head from the active probe amplifier.
② Push the new probe head into the active probe amplifier straightly.
When single-ended probe head is used, pay attention to their
polarities.
2. To replace the probe tip
The probe tip and probe head are connected with screw thread, so please
note the screw rotation and strength when removing and installing the
probe tip.
3. To replace the nickel wire
If the nickel wire of the solder-in probe head under use becomes damaged
or breaks off, you can replace a new one. The probe head nickel wire
should satisfy the following size requirement, that is, the length must be
shorter than 5 mm.
Note: If the length of the nickel wire is longer than 5 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 MSO/DS7000/MSO8000 series oscilloscope can provide offset voltage
to the PVA7000 series active probe. 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 PVA7000 series active probe to the channel input terminal (e.g. CH1)
of the MSO/DS7000/MSO8000 oscilloscope.
2. Open the probe offset voltage control menu of the
MSO/DS7000/MSO8000 oscilloscope (front panel operation: 1 → Probe
→ Bias Voltage) and rotate the knob to adjust the value.
RIGOL
User Guide for PVA7000 Series Active Probe 17
To Calibrate the Probe
Before using, you should calibrate the PVA7000 series active probe. Follow the
procedures below to calibrate the PVA7000 active probe:
1. Connect the PVA7000 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: 1 →
Probe → Probe-Cal), and the oscilloscope starts to calibrate the probe.
The calibration will last for about 40 to 50 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.
Note: Technical specifications of the PVA7000 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. Users can query the information
about the manufacturer, model, serial number and the last calibration time of
the probe through the menu operation: 1 → Probe → Probe Info.
