Product Description
The P6616 general-purpose logic probe connects the Tektronix
MSO/DPO5000 Series and MSO4000B Series of mixed-signal
oscilloscopes to digital buses and signals on your target system.
The probe contains 16 data channels split between two lead sets
(GROUP 1 and GROUP 2).
All leads include a ground connection at the tip. You can
connect the probe leads separately to the target system, or group
the leads together using the probe tip holders.
Connecting the Probe to the Oscilloscope
Connect the probe as shown in the illustration below.
1. Insert the probe label-side up into the connector on the
oscilloscope.
2. To remove the probe, squeeze the buttons on the side and
pull out the probe.
Connecting the Probe to Your Circuit
Attach the probe to the circuit using the connectors and adapters
shown on the back of these instructions. Select the best method
for your needs, and then proceed to Setting up the Probe.
Setting Up the Probe
To set and view the digital channel parameters, do the
following:
On MSO/DPO5000 Series instruments, select
Vertical>Digital Setup.
On MSO/DPO4000B Series instruments, push the D15–D0
button.
The parameters listed below can be set on each digital channel:
Threshold voltage and vertical position (the default
threshold setting is 1.4 V)
Signal height and position (set once for all 16 channels)
Channel label
To set and view bus characteristics, do the following:
On MSO/DPO5000 Series instruments, use the controls in
the Bus Setup screen.
On MSO/DPO4000B Series instruments, push the B1 to
B4 buttons.
The setup screens allow you to set and view bus characteristics
such as:
Clock type
Bus type (Serial or Parallel)
Bus width
Display format (Hex, Binary, or ASCII symbols)
Parallel bus setup information is resident on some oscilloscope
models. However, for other buses such as SPI and I2C, you
must have the appropriate option. See your oscilloscope manual
or product data sheet for nomenclature and ordering details.
Functional Check
Logic activity immediately displays on all connected, active
channels. If you do not see an active signal:
1. Push the Trigger button.
2. Select Edge for trigger type.
3. Select the channel that you are setting up as the source.
4. On MSO/DPO4000B Series instruments, push the Autoset
button.
If you do not see an active signal, try another probe channel (or
analog probe) to verify circuit activity at the test point.
Typical Application
1. Use the P6616 probe to view digital signals on a system
bus.
2. Use an analog probe, such as the TPP0500 or TPP1000
active probe to view analog waveform information.

The following standard accessories ship with the probe and are
