Introduction
Overview
The PV1 active probe is an ideal solution for measuring digital transmissions up
to 2.5 Gbps. An amplifier near the probe tip ensures signal integrity, and a small,
lightweight design makes it easy to install many probes for measuring multilane buses.
These single-ended, ground-referenced probes are compatible with any 50Ω
terminated oscilloscope for browsing or attachment and are the perfect addition
to any laboratory for monitoring all digital communications from low-speed
LVCMOS to high-speed SerDes such as MIPI D-PHY and C-PHY.
User Guide Documentation
This User Guide will provide the relevant information for an end user to setup

Preparing the Test Points
There are three methods of probing signals on a target PCB.
1. Attach to Header at test point
2. Attach to Header with extension wires
3. Direct probing without installed header
Attach to Header at Test Point
For this method, a 0.1-in Header is soldered to the PCB at each test point
location. One pin should be soldered to Signal and the other pin should be
soldered to Ground.

Attach to Header with Extension Wires
For this method, extension wires are soldered to the PCB at each test point
location. This method can be used for fine pitch test points, or when the
distance between signal and ground is not 0.1-in. A 0.1-in Header is then
soldered to the extension wires. It is important to keep the length of the
extension wire as short as possible. For high-speed signals, a damping resistor
is recommended (see Application example #1).

Direct Probing Without Installed Header
For direct probing, a 0.1-in Header is inserted into the PV1 Active Probe head
and contact is made with the desired test point location. Care must be taken to
connect both Signal and Ground at the same time. A ground extension wire
might facilitate probing in this manner.

User Guide
Application example #1 shows the "Direct probing" method where the Header is
inserted into the PV1 Active probe and contact is made with the test point. In
this application, there is no Header soldered to the PCB and the probe is held in
place by a human hand. Also shown in the photo are some “Headers with
extension wires”.
Figure 9 Application example#2
Application example #2 shows the probing of a MIPI Lane using four PV1 Active
Probes. This example illustrates the “Attach to Header at test point” method, as
four Headers are soldered to the PCB, and the probes simply attach to them.

Step-by-Step Procedure
1. Plug 12VDC Wall Adapter into a suitable AC Outlet
2. Connect Wall Adapter DC Output to PV1PSU
3. Connect PV1 Active Probe Power cable to PV1PSU
4. Connect PV1 Active Probe Signal cable to Scope or Analyzer
5. Power ON the PV1PSU (observe V+ and V- LEDs will come on)
6. Perform measurements using Introspect Analyzer or oscilloscope
