Pollution d

A measure of the contaminants that could occur in the environment around and within a product. Typically the internal
environment inside a product is considered to be the same as the external. Products should be used only in the environment
for which they are r ated.

Pollution degree 1. No pollution or only dry, nonconductive pollution occurs. Products in this category are generally
encapsulated, hermetically sealed, or located in clean rooms.

Pollution degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a temporary conductivity that is
caused by condensation must be expected. This location is a typical office/home environment. Temporary condensation
occurs only when the product is out of service.

Pollution degree 3. Conductive pollution, or dry, nonconductive pollution that becomes conductive due to condensation.
These are sheltered locations where neither temperature nor humidity is controlled. The a rea is protected from direct
sunshine, rain, or direct wind.

Pollution degree 4. Pollution that generates persistent conductivity through conductive dust, rain, or snow. Typical
outdoor locations.

Connecting Probes

The oscilloscope supports probes with the following:

1. Tektronix Versatile Probe Interface

(TekVPI)
These probes support two-way

communication with the oscilloscope
through on-screen menus and remotely
through programmable support. The
remote control is useful in applications
like ATE where you want the system to
preset probe parameters.

2. Tektronix Versatile Probe Interface

(TekVPI) for Passive Probes
These probes build upon the functionality

of the TekVPI interface. Each probe
is matched with its corresponding
oscilloscope channel, allowing the
oscilloscope to optimize the signal input
path. This provides AC compensation
across the frequency band.

Installation

3. TPA-BNC Adapter

The TPA-BNC Adapter allows you to
use TEKPROBE II probe capabilities,
such as providing probe power, and
passing scaling and unit information to
the oscilloscope.

4. BNC Interfaces

Some of these use TEKPROBE
capabilities to pass the waveform signal
and scaling to the oscilloscope. Some
only pass the signal and there is no other
communication.

5. Logic Probe Interface

The P6616 probe provides 16 channels
of digital (on or off state) information.

6. The TPA-N-VPI Adapter allows you to

use TekVPI probes in the RF input.

For more information on the m any probes available for use with MDO4000B Series oscilloscopes, visit the Oscilloscope
Probe and Accessory Selector Tool on the Tektronix website at www.tektronix.com.

Compensating a T PP0500 or TPP1000 Passive Voltage Probe

The MDO4000B Series oscilloscopes can automatically compensate TPP0500 and TPP1000 probes. This eliminates the
need for manual probe compensation, as is typically performed with other probes.

Each compensation generates values for a specific probe and channel combination. If you want to use the probe on another
channel and desire to compensate the new probe-channel pair, you must run a new set of compensation steps for that new
combination.

Quick Tips

To position the waveform appropriately, Autoset may change the vertical position. Autoset always sets vertical offset
to0V.

If you use Autoset when no channels are displayed, the instrument turns on channel 1 and scales it.

If you use Autoset and the oscilloscope detects a video signal, the oscilloscope automatically sets the trigger type to
video and makes other adjustments to display a stable video signal.

Acquisition Concepts

Before a signal can be displayed, it must pass through the input channel where it is scaled and digitized. Each channel
has a dedicated input amplifier and digitizer. Each channel produces a stream of digital data from which the instrument

7. Push Delay on th
On when you want to delay the acquisition

relative to the trigger event.

With Delay set to On, turn the Horizontal Position knob counterclockwise to increase the delay. The trigger point will move
to the left and ultimately outside of the acquired waveform. Then you can adjust the Horizontal Scale knob to acquire more
detail around the area of interest at the center of the screen.

When this delay is on, the trigger point separates from the horizontal expansion point. T he horizontal expansion point
stays at the center of the screen. The trigger point can move off the screen. When this happens, the trigger marker turns
to point in the direction of the trigger point.

Use the delay feature when you want to acquire waveform detail that is separated from the trigger event by a significant
interval of time. For example, you can trigger on a sync pulse that occurs once every 10 ms and then look at high-speed
signal characteristics that occur 6 ms after the sync pulse.

When the delay feature is s et to Off, the expansion point is tied to the trigger point so that scale changes are centered
around the trigger point.

see when you choose to display a bus always show the physical layer bus activity. In the physical layer display, bits that were
transmitted earlier are to the left, and bits that were transmitted later are to the right.

I2C, and CAN buses transmit the MSB (most significant bit) first

SPI buses do not specify a bit order

74 MDO4000B Series Oscilloscopes User Manual

When and Why to Turn On MagniVu

Tektronix MagniVu acquisition technology allows you to have higher timing resolution so that you can more accurately
determine edge placement and make more precise timing measurements on digital edges. Using MagniVu, you can see
up to 32 times more detail than you can using normal digital channel sampling.

The MagniVu record is acquired in parallel to the main digita l acquisition and is available at any time, running or stopped.
MagniVu provides an ultra high resolution view of your data sampled at a maximum resolution of 60.6 ps for 10,000 points
centered around the trigger.

NOTE. MagniVu centers itself around the trigger point. If you turn MagniVu on while using a large record length and you are

looking somewhere other than the trigger point, then the digital signal may be off screen. In most of these cases, you can find
the digital record by looking for the digital signal in the upper overview and panning accordingly.

NOTE. You should turn on MagniVu when light gray shading is displayed to indicate the uncertainty of the edge position. If

the shading is not displayed, you do not need to use MagniVu. (See page 109, Viewing Digital Channels.)

Resolution Bandwidth

The resolution bandwidth (RBW) determines the level to which the oscilloscope can resolve individual frequencies in
the frequency domain. For example, if the test signal contains two carriers separated by 1 kHz, you will not be able to
discriminate between them unless the RBW is less than 1 kHz.

The views below both show the same signal. The difference between them is their RBW.

Lower (narrower) RBWs take longer to process,
but have finer frequency resolution and a lower
noise floor.

Higher (wider) RBWs take less time to process, but have less frequency resolution
and a higher noise floor.
