Pollution Degree Description

asure of the contaminants that could occur in the environment around and within a p roduct. Typically the internal

Ame 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 rated.

Pollution Degree 1. No pollution or only dry, nonconductive pollution occurs. Products in this category are generally

capsulated, hermetically sealed, or located in clean rooms.

llution Degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a temporary conductivity that is

Signal Path Compensation

Signal Path Compensation (SPC) corrects for DC inaccuracies caused by temperature variations and/or long-term drift. Run the compensation whenever the ambient temperature has changed by more than 10 °C (18 °F) or once a week if you use vertical settings of 5 mV/division or less. Failure to do so may result in the instrument not meeting warranted performance levels at those volts/div settings.

To compensate the signal path:

1. Warm up the oscilloscope for at least 20 minutes. Remove all input signals (probes and cables) from channel inputs. Input signals with AC components adversely affect SPC.

Connecting Your Oscilloscope to a Computer

You may want to document your work for future reference. Instead of saving screen images and waveform data to a CompactFlash storage device or USB ﬂash drive, and then generating a report later, you may want to send the image or waveform data directly to a remote PC for analysis. You may also want to control an oscilloscope at a remote location from your computer. (See page 124, Saving a Screen Image.) (See page 125, Saving and Recalling Waveform Data.)

Two ways to connect your oscilloscope to a computer are through the VISA drivers and the e*Scope Web-enabled tools. Use VISA to communicate with your oscilloscope from your computer through a software application. Use e*Scope to communicate with your oscilloscope through a Web browser.

Using VISA

VISA lets you use your MS-Windows computer to acquire data from your oscilloscope for use in an analysis package that runs on your PC, such as Microsoft Excel, National Instruments LabVIEW, or a program of your own creation. You can use a common c

ommunications connection, such as USB, Ethernet, or GPIB, to connect the computer to the oscilloscope.

2. Connect the oscilloscope to your computer

with the appropriate USB or Ethernet cable.

To communicate between the oscilloscope and a GPIB system, connect the oscilloscope to the TEK-USB-488 GPIB-to-USB Adapter with a USB cable. Then connect the adapter to your GPIB system with a GPIB cable. Cycle the power on the oscilloscope.

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 one (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.

Waveform Record

The instrument builds the waveform record through use of the following parameters:

Sample interval: The time between recorded sample points. Adjust this by turning the Horizontal Scale knob or changing the record length with the bezel buttons.

Record length: The number of samples required to ﬁll a waveform record. Set this by pushing the Acquire button and using the resulting lower- and side-bezel menus.

Trigger point: The zero time reference in a waveform record. It is shown on the screen by an orange T.

Horizontal position: When Delay Mode is on, this is the time from the trigger point to the expansion point. Adjust this by turning the Horizontal Position knob.

Use a positive time to acquire the record after the trigger point. Use a negative time to acquire it before the trigger point.

Expansion point: The point that the horizontal scale expands and contracts around. It is shown by an orange triangle.

How the Analog Acquisition Modes Work

Sample mode retains the ﬁrst sampled point

from each acquisition interval. Sample is the default mode.

Peak Detect mode uses the highest and lowest of all the samples contained in two consecutive acquisition intervals. This mode only works with real-time, noninterpolated sampling and is useful for catching high frequency glitches.

46 MSO4000 and DPO4000 Series Oscilloscopes User Manual

Hi Res mode calculates the average of all the samples for each acquisition interval. This mode also

only works with real-time, noninterpolated sampling. Hi-Res provides a higher-resolution, lower-bandwidth waveform.

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. The 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 set to Off, the expansion point is tied to the trigger point so that scale changes are centered around the trigger point.

Setting Up a Serial or Parallel Bus

Your oscilloscope can decode and trigger on signal events or conditions that occur on:

I2C and SPI serial buses if the DPO4EMBD application module is installed

USB 2.0 serial buses if the DPO4USB application module is installed (edge-trigger only for high-speed bus)

CAN and LIN serial buses if the DPO4AUTO or DPO4AUTOMAX application m odule is installed. LIN works on DPO4000s with a serial number greater than C020000 or on any MSO4000

FlexRay serial buses if the DPO4AUTOMAX application module is installed. FlexRay works on DPO4000’s with a serial number greater than C02000 or on any MSO4000

RS-232, RS-422, RS-485, and UART serial buses if the DPO4COMP application module is installed

Audio buses (I2S, Left Justiﬁed (LJ), Right Justiﬁed (RJ), and TDM) if the DPO4AUDIO application module is installed

Physical Layer Bus Activity

Oscilloscope waveform traces from analog channels 1 to 4, digital channels D15 to D0, and the traces you 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

RS-232 and LIN buses transmit the LSB (least signiﬁcant bit) ﬁrst

NOTE. The oscilloscope displays the decode traces and event tables for all buses with the MSB on the left and LSB

on the right.

For example, an RS-232 signal (after the start bit) might be high, high, high, low, high, low, low, and high. Since the RS-232 protocol uses high for z ero and low for one, this value would be 0001 0110.

Since the decode displays the MSB ﬁrst, the oscilloscope reverses the order of the bits and displays 0110 1000. If the bus display is set to hex, the value displays as 68. If the bus display is set to ASCII, the value displays as h.

Trigger Setup

This section contains concepts and procedures for setting up the oscilloscope to trigger on your signal.

Triggering Concepts

Trigger Event

The trigger event establishes the time-reference point in the waveform record. All waveform record data is located in time with respect to that point. The instrument continuously acquires and retains enough sample points to ﬁll the pretrigger portion of the waveform record. That is the part of the waveform that is displayed before, or to the left of, the triggering event on screen. When a trigger event occurs, the instrument starts acquiring samples to build the posttrigger portion of the waveform record, that is, the part displayed after or to the right of the trigger event. After a trigger is recognized, the instrument will not accept another trigger until the acquisition is complete and the holdoff time has expired.

Untrigg

ered display

Trigger

ed display

Trigger Modes

The trigger mode determines how the instrument behaves in the absence of a trigger event:

Normal trigger mode enables the instrument to acquire a waveform only when it is triggered. If no trigger occurs, the last waveform record acquired remains on the display. If no last waveform exists, no waveform is displayed.

Auto trigger mode enables the instrument to acquire a waveform even if a trigger does not occur. Auto mode uses a timer that starts when the acquisition is started, and the pretrigger information is obtained. If a trigger event is not detected before the timer times out, the instrument forces a trigger. The length of time it waits for a trigger event depends on the time base setting.

Auto mode, when forcing triggers in the absence of valid triggering events, does not synchronize the waveform on the display. The waveform will appear to roll across the screen. If valid triggers occur, the display will become stable.

You can also force the instrument to trigger by pushing the front-panel Force Trig button.

Triggering on Buses

You can use your oscilloscope to trigger on CAN, I2C, SPI, RS-232, RS-422, RS-485, UART, LIN, FlexRay, I2S, Left Justiﬁed, Right Justiﬁed, and TDM buses, if you have the appropriate DPO4AUTO, DPO4AUTOMAX, DPO4EMBD, DPO4COMP, or DPO4AUDIO application module installed. The MSO4000 Series can trigger on parallel buses without an application module. The oscilloscope can display both physical layer (as analog waveforms) and protocol level information (as digital and symbolic waveforms).

To set up the bus trigger:

1. If you have not already deﬁned your bus using the front-panel B1 and B2 buttons (and B3 and B4 on the MSO4000 Series), do so now. (See page 50, Setting Up a Serial or Parallel Bus.)

2. Push Trigger Menu.

I2C, SPI, USB, CAN, LIN, and FlexRay Bus Trigger Data Matching

Rolling window byte matching for I2C, SPI, USB, and FlexRay. To use a rolling window to trigger on data, you

deﬁne the number of bytes to match. Then the oscilloscope uses a rolling window to ﬁnd any match within a packet, with the window rolling one byte at a time.

For example, if the number of bytes is one, the oscilloscope will attempt to match the ﬁrst byte, second byte, third, and so on within the packet.

If the number of bytes is two, the oscilloscope will try to match any two consecutive bytes, such as one and two, two and three, three and four, and so on. If the oscilloscope ﬁnds a match, it will trigger.

With FlexRay, obtain a rolling window match by setting the Byte Offset to Don’t care. Do this by pressing the front-panel Trigger button, followed by setting the lower-bezel Type to Bus, Trigger On to Data, pressing Data, and entering the byte offset with the side menu and multipurpose knob a.

Speciﬁcby USB, CAN, and FlexRay.

For I2C and SPI, enter the number of bytes to match the number of bytes in the signal. Then use don’t cares (X) to mask the bytes that you are not interested in.

For I2C, push the lower-bezel Trigger On to trigger on Address/Data.PushAddress. On the side-bezel menu, push Address, address. The data will be matched starting at the ﬁrst byte without using a rolling window.

For USB, triggering occurs when the user-selected data input matches the data and qualiﬁer in the signal starting at the byte offset. Set the number of bytes to match the number of bytes of interest. Use the data qualiﬁer to perform: =, !=,<,>,

For CAN, the ﬁrst byte. Set the number of bytes to match the number of bytes of interest. Use the data qualiﬁer to perform: =, !=, <, >, >=, and <= operations. Triggering on identiﬁer and data always matches the identiﬁer and data selected by the use

You can trigger on a speciﬁc data value for RS-232 bytes. If you deﬁned an end-of-packet character to use for RS-232 bus decoding, you can use the same end-of-packet c haracter as a data value for trigger data matching. To do so, choose the Tx End of Packet or the Rx End of Packet character as the Trigger On selection.
