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 an ATE (automated test environment) where you want the system to preset probe parameters.

NOTE.

For more information on the many probes available for use with MSO2000B and

DPO2000B Series oscilloscopes, visit the

Oscilloscope Probe and Accessory Selector tool on the Tektronix website.

2. TPA-BNC Adapter

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

NOTE.

To use a TekVPI probe and a

TPA-BNC adapter, connect a TekVPI external power adapter (Tektronix part number 119 ‑ 7465 ‑ XX) to the side panel

Probe Power connector.

3. Plain BNC Interfaces

Some probes use TekProbe capabilities to pass the waveform signal and scaling to the oscilloscope. Other probes only pass the signal and there is no communication.

4. Digital Probe Interface

(MSO2000B series only)

The P6316 probe provides 16 channels of digital (on or off state) information.

For more information on the many probes available for use with MSO2000B and DPO2000B series oscilloscopes, refer to www.tektronix.com.

Powering On the Oscilloscope

Ground the Oscilloscope and Yourself

Before pushing the power switch, connect the oscilloscope to an electrically neutral reference point, such as earth ground.

Do this by plugging the three-pronged power cord into an outlet grounded to earth ground.

Grounding the oscilloscope is necessary for safety and to take accurate measurements. The oscilloscope needs to share the same ground as any circuits that you are testing.

To connect the power cord and power on the oscilloscope:

Quick Tips

If you are working with static sensitive components, ground yourself. Static electricity that builds up on your body can damage static-sensitive components.

Wearing a grounding strap safely sends static charges on your body to earth ground.

10 MSO2000B and DPO2000B Series Oscilloscopes User Manual

Powering Off the Oscilloscope

To power off the oscilloscope and remove the power cord:

Functional Check

Perform this quick functional check to verify that your oscilloscope is operating correctly.

1. Connect the oscilloscope power cable as described in Powering On the

Oscilloscope. (See page 10.)

3. Connect the TPP0200/TPP0100 probe tip and reference lead to the PROBE

COMP connectors on the oscilloscope.

4. Push Default Setup.

5. Push Autoset. The screen should now display a square wave, approximately

5 V at 1 kHz.

NOTE.

For best performance, it is recommended that you set the Vertical scale to 1 V.

If the signal appears but is misshapen, perform the procedures for compensating

the probe. (See page 12.)

If no signal appears, rerun the procedure.

If this does not remedy the situation, have the oscilloscope serviced by qualified service personnel.

Compensating a Passive Voltage Probe

Whenever you attach a passive voltage probe for the first time to any input channel, compensate the probe to match it to the corresponding oscilloscope input channel.

To properly compensate your passive probe:

1. Follow the steps for the functional

check. (See page 11.)

2. Check the shape of the displayed waveform to determine if your probe is properly compensated.

Properly compensated Under compensated Over compensated

12 MSO2000B and DPO2000B Series Oscilloscopes User Manual

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 USB flash drive and generating a report later, you may want to get a copy of the image or waveform data directly from a remote

PC for analysis. You may also want to control an oscilloscope at a remote location from your computer. (See page 113,

Saving a Screen Image.) (See page 114, Saving and Recalling Waveform Data.)

Two ways to connect your oscilloscope to a computer are through the VISA (Virtual Instrument Software Architecture) 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 communications connection, such as USB or Ethernet, to connect the computer to the oscilloscope.

To set up VISA communications between your oscilloscope and a computer:

1. Load the VISA drivers on your computer.

You will find the drivers on the appropriate

CD that comes with your oscilloscope or at the Tektronix software finder Web page

Acquire the Signal

This section describes concepts of and procedures for setting up the oscilloscope to acquire the signal as you want it to.

Setting Up Analog Channels

Use front-panel buttons and knobs to set up your oscilloscope to acquire signals using the analog channels.

1. Connect a TPP0200/TPP0100 probe or a

TekVPI probe to the input signal source.

2. Push Default Setup.

NOTE.

If you are using a probe that does not supply probe encoding, set the attenuation

(probe factor) on the oscilloscope vertical menu to match the probe. The default attenuation for the oscilloscope is 10X and is set in the Probe Setup lower-bezel menu of any analog channel.

3. Select the input channel by pushing the front-panel buttons.

4. Push Autoset.

40 MSO2000B and DPO2000B Series Oscilloscopes User Manual

Acquire the Signal

5. Push the desired channel button. Then adjust the vertical position and scale.

6. Adjust the horizontal position and scale.

The horizontal position determines the number of pretrigger and posttrigger samples.

The horizontal scale determines the size of the acquisition window relative to the waveform. You can scale the window to contain a waveform edge, a cycle, several cycles, or thousands of cycles.

Quick Tip

Use the zoom feature to see multiple cycles of your signal in the upper part, and a single cycle in the lower part of the

display. (See page 105, Using Wave Inspector to Manage Long Record Length Waveforms.)

Labeling Channels and Buses

You can add a label to the channels and buses shown on the display for easy identification. The label is placed on the waveform baseline indicator in the left side of the screen. The label can have up to 32 characters.

To label a channel, push a channel input button for an analog channel to label a channel.

1. Push a front panel button for an input channel or a bus.

Quick Tips

To position the waveform appropriately, Autoset may change the vertical position. Autoset always sets vertical offset to 0 V.

If you use Autoset when no channels are displayed, the oscilloscope 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.

To manually set the oscilloscope to view a video signal in an IRE graticule:

1. Set the Trigger Type to Video.

2. Set the Vertical Scale to 143mV/div.

3. Select the proper input channel Attenuation for the probe or cable being used to feed the video signal to the oscilloscope.

4. If necessary, connect a 75 ohm pass-through terminator to the oscilloscope input. For example, you need to add a terminator when you use a 75-ohm cable between the video signal and the oscilloscope.

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 oscilloscope extracts waveform records.

Sampling Process

Acquisition is the process of sampling an analog signal, converting it into digital data, and assembling it into a waveform record, which is then stored in acquisition memory.

Input signal Sampled points

Digital values

MSO2000B and DPO2000B Series Oscilloscopes User Manual 45

Real-Time Sampling

MSO2000B and DPO2000B series oscilloscopes use real-time sampling. In real-time sampling, the oscilloscope digitizes all of the points it acquires using a single trigger event.

Record points

Sampling rate

Waveform Record

The oscilloscope builds the waveform record through the 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 the Delay mode is on, this is the time from the trigger point to the expansion point. Adjust this by turning the Horizontal Position knob.

When the Delay mode is off, the expansion point is fixed to the trigger point. (Push the Acquire front panel button to set the Delay mode.)

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.

46 MSO2000B and DPO2000B Series Oscilloscopes User Manual

How the Analog Acquisition Modes Work

FilterVu Noise Filter Foreground mode retains the first sampled point from each acquisition interval. This mode is also called

Sample in other oscilloscopes. This is the default mode.

FilterVu Glitch Capture Background mode uses the highest and lowest of all the samples contained in two consecutive acquisition intervals. At fast time per division settings, the Glitch Capture Background mode is unavailable. This mode is also called Peak Detect in other oscilloscopes.

Average mode calculates the average value for each record point over a user-specified number of acquisitions. Average uses

Sample mode for each individual acquisition.

Use Average mode to reduce random noise.

Changing the Acquisition Mode, Record Length, and Delay Time

Use this procedure to change the acquisition mode.

4. Turn multipurpose knob a to set the number of waveforms to average over.

5. Push Record Length.

Choose 100 k or 1.00 M points. The selections depend on the horizontal time per division setting. 125 k and 1.25 M records lengths are available at slower time per division settings.

6. Push the lower-bezel Delay button to select

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.

48 MSO2000B and DPO2000B Series Oscilloscopes User Manual

Acquire the Signal

Using Roll Mode

Roll mode gives a display similar to a strip chart recorder for low-frequency signals. Roll mode lets you see acquired data points without waiting for the acquisition of a complete waveform record.

Roll mode is enabled when the trigger mode is auto and the horizontal scale is set to 40 ms/division or slower.

Quick Tips

Roll mode is disabled when you switch to Average acquisition mode, use digital channels, use math waveforms, turn on a bus, switch to Normal trigger, or set the horizontal scale to 20 ms per division or faster.

Zoom is disabled when you use Roll mode.

Push Run/Stop to halt Roll mode.

Setting Up a Serial or Parallel Bus

Your oscilloscope can decode and trigger on:

I 2 C and SPI serial buses if the DPO2EMBD application module is installed

CAN and LIN serial buses if the DPO2AUTO application module is installed

RS-232, RS-422, RS-485, and UART serial buses if the DPO2COMP application module is installed

Parallel buses if you are using an MSO2000B series oscilloscope

(See page 13, Application Module Free Trial.)

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 zero 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.

RS-232

If you defined an end-of-packet character to use for RS-232 decoding, the stream of bytes will be displayed as packets.

When decoding an RS-232 bus in ASCII mode, a large dot indicates that the value represents a character outside the printable

ASCII range.

7. Turn multipurpose knob a to scroll through the list of digital channels. Turn multipurpose knob b to position the selected channel.

As you position channels close to each other on the display, the oscilloscope groups the channels, and adds the group to the pop-up list. You can select the group from the list to move all the channels in the group instead of individual channels.

8. Push the lower-bezel Thresholds button.

You can assign a different threshold value to each pod.

9. Push the lower-bezel Edit Labels button and create the label. You can create labels through the front panel or with an optional

USB keyboard. (See page 41, Labeling

Channels and Buses.)

10. Push the lower-bezel Height button repeatedly to set the signal height. You only need to do this once to set the height for all of the digital channels.

Quick Tip

Use the zoom feature to see multiple cycles of the signal in the upper part, and a single cycle in the lower part of the

display. (See page 105, Using Wave Inspector to Manage Long Record Length Waveforms.)

The lead for each digital channel has a color-coded band for easy identification. The ground leads are shorter and have black wires.

Digital channels store a high or low state for each sample. The threshold that separates a high from a low can be set for all the channels in GROUP 1 or in GROUP 2. The threshold can not be set for individual channels.

Reducing Unwanted Noise With FilterVu

You can use FilterVu to filter unwanted noise from your signal and still capture glitches. The oscilloscope does this by superimposing a filtered foreground waveform over a glitch capture background waveform.

The filtered waveform uses a variable low-pass filter to block out noise, yielding a cleaner waveform. When the noise filter is adjusted to the minimum bandwidth setting, no more than 1% of high-frequency content that could cause the oscilloscope to alias will pass through the filter.

The glitch capture waveform shows signal details up to the full bandwidth of the oscilloscope. The oscilloscope captures pulses as narrow as 5 ns, using peak detect min/max sampling.

When your signal is filtered, the glitch capture waveform changes color to distinguish it from the filtered waveform. When the signal is filtered, you can independently adjust the intensity of the glitch capture waveform. When the signal is not filtered, the intensity of the glitch capture waveform depends on the overall intensity (under the Intensity button on the oscilloscope front panel).

Acquire the Signal

FilterVu, Bandwidth Limit, and Averaging

You can use FilterVu, Bandwidth Limits, or Average mode to reduce noise in your signal. Each has benefits.

NOTE.

FilterVu does not apply to triggering. To reduce the effects of noise on your signal while triggering, use Bandwidth

Limits or use Coupling settings.

Use FilterVu when you want to do the following:

Adjust your filter frequency with more granularity than the Bandwidth Limit provides.

Adjust all channels to the same frequency.

Acquire a non-repetitive or a single-shot signal.

Use Bandwidth Limit when you want to do the following:

Filter only one channel.

Trigger on a filtered signal.

Acquire a non-repetitive or a single-shot signal.

Use Average mode when you want to do the following:

Acquire a repetitive signal.

Noise on your signal is random (not correlated with the trigger).

Increase the vertical precision of your acquisition.

NOTE.

You can use FilterVu with Bandwidth Limit. You cannot use FilterVu with Average mode.

Quick Tips

You can choose to save to a file with full resolution (every point that was captured) or reduced resolution (fewer points).

When your signal is filtered, only the reduced-resolution waveform is guaranteed to be filtered to the chosen frequency.

Sometimes, the filter is unable to produce a full-resolution waveform with a frequency as low as the chosen frequency.

The frequency of the full-resolution waveform is shown in the saved file.

When the glitch capture background is on, a saved waveform file includes both the foreground and the background data.

Reference waveforms can be filtered; the chosen noise filter frequency also applies to references. Reference waveforms also have a glitch capture background.

Reference waveforms are always saved at full resolution. Unlike saving a waveform to a file, there is no reduced resolution option.

When the signal is not filtered, most measurements are taken on the foreground waveform. The min, max, and peak-to-peak measurements are taken on the glitch capture background, because they measure the smallest and largest amplitudes in the waveform.

When the signal is filtered, all measurements are taken from the filtered waveform.

Dual-waveform math can be filtered; the chosen noise filter frequency also applies to math. Dual-waveform math does not have a glitch capture background.

MSO2000B and DPO2000B Series Oscilloscopes User Manual 61

Acquire the Signal

Search uses the glitch capture background, when available. This lets you better search for spikes and other anomalies.

Serial bus decode uses a full-resolution sample (foreground) waveform. When filtering is active, that waveform might not be filtered to the chosen frequency.

Using FilterVu

By default, the noise filter cutoff frequency is set to the full bandwidth of the oscilloscope when you use FilterVu. To invoke the variable low-pass filter (noise filter), turn the multipurpose knob counterclockwise. The oscilloscope passes lower frequency signals which results in a cleaner-looking waveform. The noise frequency readout displays frequencies that the oscilloscope includes in the foreground waveform. The oscilloscope displays higher frequency components in the background waveform, up to the bandwidth of the MSO2000B or DPO2000B model.

NOTE.

The oscilloscope always displays the noise filter cutoff frequency in the upper right part of the screen. The cutoff frequency reflects the -3 dB point.

Trigger Setup

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 oscilloscope 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 oscilloscope 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 oscilloscope will not accept another trigger until the acquisition is complete and the holdoff time has expired.

Untriggered display Triggered display

Trigger Modes

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

Normal trigger mode enables the oscilloscope 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 oscilloscope 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 oscilloscope 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 oscilloscope to trigger. To do so, push the front-panel Force Trig button.

64 MSO2000B and DPO2000B Series Oscilloscopes User Manual

Trigger Setup

Trigger Holdoff

Adjust holdoff to obtain stable triggering when the oscilloscope is triggering on undesired trigger events.

Trigger holdoff can help stabilize triggering, since the oscilloscope does not recognize new triggers during the holdoff time. When the oscilloscope recognizes a trigger event, it disables the trigger system until acquisition is complete. In addition, the trigger system remains disabled during the holdoff period that follows each acquisition.

Holdoffs

Trigger Coupling

Trigger coupling determines what part of the signal is passed to the trigger circuit. Edge triggering can use all available coupling types: DC, Low Frequency Rejection, High Frequency Rejection, and Noise Rejection. All other trigger types use DC coupling only.

The cutoff frequency for low frequency rejection is 65 kHz. The cutoff frequency for high frequency rejection is 85 kHz.

Horizontal Position

When Delay Mode is on, use horizontal position to acquire waveform detail in a region that is separated from the trigger location by a significant interval of time.

MSO2000B and DPO2000B Series Oscilloscopes User Manual 65

Trigger Setup

1. Adjust the position (delay) time by rotating the Horizontal Position knob.

2. Turn the horizontal Scale knob to acquire the detail that you need around the position (delay) expansion point.

The part of the record that occurs before the trigger is the pretrigger portion. The part that occurs after the trigger is the posttrigger portion. Pretrigger data can help you troubleshoot. For example, to find the cause of an unwanted glitch in your test circuit, you can trigger on the glitch and make the pretrigger period large enough to capture data before the glitch. By analyzing what happens before the glitch, you may uncover information that helps you find the source of the glitch. Alternatively, to see what is happening in your system as a result of the trigger event, make the posttrigger period large enough to capture data after the trigger.

Slope and Level

The slope control determines whether the oscilloscope finds the trigger point on the rising or the falling edge of a signal.

The level control determines where on that edge the trigger point occurs.

The oscilloscope provides a long horizontal bar or bars across the graticule to temporarily show the trigger level.

1. Turn the front-panel Trigger Level knob to adjust the trigger level without going to a menu.

2. Push the Force Trig button to force the oscilloscope to trigger.

Trigger conditions

Trigger on a rising or falling edge, as defined by the slope control. Coupling choices are DC, LF Reject, HF

Edge triggers are the simplest and most commonly used trigger type, with both analog and digital signals.

An edge trigger event occurs when the trigger source passes through a specified voltage level in the specified direction.

Trigger on pulses that are less than, greater than, equal to, or not equal to a specified time. You can trigger on positive or negative pulses. Pulse width triggers are primarily used on digital signals.

Trigger on a pulse amplitude that crosses one threshold but fails to cross a second threshold before recrossing the first. You can detect positive or negative (or either) runts, or only those wider than, less than, greater than, equal to, or not equal to a specified width. Runt triggers are primarily used on digital signals.

Trigger when all channels transition to the specified state. Use multipurpose knob a to select a channel.

Push the appropriate side-bezel button to set that channel's state to High (H), Low (L), or Don't Care (X).

Use the Clock side-bezel button to enable clocked

(state) triggering. You can have at most a single clock channel. Push the Clock Edge bottom bezel button to change the polarity of the clock edge. Turn off clocked triggering and return to unclocked (pattern) triggering by selecting the clock channel and setting it to high, low, or don't care.

For unclocked triggering, by default, triggering occurs when the selected condition goes true. You can also select triggering when the condition goes false, or time-qualified triggering.

You can use up to 20 channels for a logic trigger

(4 analog and 16 digital) with MSO2000B series oscilloscopes.

C, SPI, CAN, and LIN Bus Trigger Data Matching

Rolling window byte matching for I

2

C, and SPI.

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.

Specific byte matching (non-rolling window matching for a specific position in the packet) for I

2

C, SPI, and CAN.

You can trigger on a specific byte for I 2 C, SPI, and CAN in several ways:

For I 2 C 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 I 2 C, push the lower-bezel Trigger On to trigger on Address/Data. Push Address. On the side-bezel menu, push

Address, and turn multipurpose knobs a and b as needed. Set the address to don't cares (X) if you want to mask the address. The data will be matched starting at the first byte without using a rolling window.

For CAN, triggering occurs when the user-selected data input matches the data and qualifier in the signal starting at 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 user, with the data starting at the first byte. No rolling window is used.

RS-232 Bus Trigger Data Matching

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 character 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.

Parallel Bus Trigger Data Matching

Optimum parallel bus trigger performance is achieved by using only analog channels or only digital channels

(MSO2000B series only).

Quick Tips

Using Probes with the TekProbe II and TekVPI Interfaces. When you attach a probe with the TekProbe II or the

TekVPI interface, the oscilloscope sets the channel sensitivity, coupling, and termination resistance automatically to match the probe requirements. Tek Probe II probes require use of the TPA-BNC Adapter. TekVPI probes require the use of a 119 ‑7465‑XX external power supply.

The Difference Between Vertical Position and Offset. Vertical position is a display function. Adjust the vertical position to place the waveforms where you want to see them. The waveform baseline locations track adjustments made to their positions.

When you adjust vertical offset, you see a similar effect, but it is actually quite different. Vertical offset is applied before the oscilloscope preamplifier and can be used to increase the effective dynamic range of the inputs. For example, you can use vertical offset to look at small variations in a large DC voltage. Set the vertical offset to match the nominal DC voltage and the signal appears in the center of the screen.

Taking Manual Measurements with Cursors

Cursors are on-screen markers that you position in the waveform display to take manual measurements on acquired data.

They appear as horizontal and/or as vertical lines. To use cursors on analog or digital channels:

1. Push Cursors.

This changes the cursor state. The three states are:

No cursors appear on the screen.

Two vertical waveform cursors appear. They are attached to the selected analog waveform or digital waveforms.

Four screen cursors appear. Two are vertical and two are horizontal. They are no longer specifically attached to a waveform.

2. Push Cursors again.

In the example, two vertical cursors appear on the selected screen waveform.

As you turn multipurpose knob a, you move one cursor to the right or left. As you turn knob b, you move the other cursor.

If you change the selected waveform by pushing the front-panel 1, 2, 3, 4, M, R, or D15-D0 button, both cursors jump to the new selected waveform.

Using Cursor Readouts

Cursor readouts supply textual and numeric information relating to the current cursor positions. The oscilloscope always shows the readouts when the cursors are turned on.

Readouts appear in the upper right corner of the graticule. If Zoom is on, the readout appears in the upper right corner of the zoom window.

When a bus is selected, the readout shows the decoded bus data in the format you have selected, hexadecimal, binary, or

ASCII (RS-232 only). When a digital channel is selected, the cursors show the values of all displayed digital channels.

NOTE.

When buses are selected, the data value at that point is displayed in the cursor readout.

For example, you might calculate power by multiplying a voltage waveform and a current waveform.

Quick Tips

Math waveforms can be created from channel or reference waveforms or a combination of them.

Measurements can be taken on math waveforms in the same way as on channel waveforms.

Math waveforms derive their horizontal scale and position from the sources in their math expressions. Adjusting these controls for the source waveforms also adjusts the math waveform.

You can zoom in on math waveforms using the inner knob of the Pan-Zoom control. Use the outer knob for positioning

the zoomed area. (See page 105, Using Wave Inspector to Manage Long Record Length Waveforms.)

Both math sources must have the same record length.

Using FFT

An FFT breaks down signals into component frequencies, which the oscilloscope uses to display a graph of the frequency domain of a signal, as opposed to the oscilloscope's standard time domain graph. You can match these frequencies with known system frequencies, such as system clocks, oscillators, or power supplies.

These are some important details about operating the FFT feature on this oscilloscope:

The area of the source waveform used to calculate the FFT is usually slightly less than one screen width of data. To see this area, turn on the gating indicators.

The FFT is calculated from 5,000 points (typical) of the source waveform. When the input area contains more than 5,000 points, the area is reduced in resolution (that is, the number of samples is reduced).

When the input area is off the screen, the FFT cannot be calculated. To display your waveform on screen, push Acquire

-> Set Horiz. Position to 0s.

Aliasing

The largest frequency in the FFT spectrum is called the Nyquist frequency. Frequency components above the Nyquist frequency will appear on screen to be below the Nyquist frequency. This is called aliasing. To eliminate aliases, try the following remedies:

MSO2000B and DPO2000B Series Oscilloscopes User Manual 101

Analyze Waveform Data

Set up the FFT so that the Nyquist frequency is above the major frequency components of your signal. To do this, adjust the Horizontal time/div, which affects the Nyquist frequency.

Use the FilterVu low-pass filter to remove aliases from the source waveform. To do this, set the filter frequency to its minimum value (while zoom is off and acquisitions are running). Aliased frequencies are reduced to no more than 1% of their original amplitude. Using a filter frequency above the minimum can reduce, but not eliminate, aliasing.

Recognize and ignore the aliased frequencies.

NOTE.

The Nyquist frequency is one-half the sample rate. When the FFT is taken from a reduced-resolution waveform, the

Nyquist frequency will be half of the reduced sample rate of the waveform, not half of the full sample rate of the oscilloscope.

Quick Tips

If desired, use the zoom feature along with the horizontal Position and Scale controls to magnify and position the

FFT waveform.

Use the default dBV RMS scale to see a detailed view of multiple frequencies, even if they have very different amplitudes.

Use the linear RMS scale to see an overall view of how all frequencies compare to each other.

The FFT feature provides four windows. Each is a trade-off between frequency resolution and magnitude accuracy.

What you want to measure and your source signal characteristics help determine which window to use. Use the following guidelines to select the best window.

Description

Hanning

This is a very good window for measuring amplitude accuracy but less so for resolving frequencies.

Use Hanning for measuring sine, periodic, and narrow band random noise. This window works on transients or bursts where the signal levels before and after the event are significantly different.

Rectangular

This is the best type of window for resolving frequencies that are very close to the same value but worst for accurately measuring the amplitude of those frequencies. It is the best type for measuring the frequency spectrum of nonrepetitive signals and measuring frequency components near DC.

Use Rectangular for measuring transients or bursts where the signal level before and after the event are nearly equal. Also, use this window for equal-amplitude sine waves with frequencies that are very close and for broadband random noise with a relatively slow varying spectrum.

Hamming

This is a very good window for resolving frequencies that are very close to the same value with somewhat improved amplitude accuracy over the rectangular window. It has a slightly better frequency resolution than the Hanning.

Use Hamming for measuring sine, periodic, and narrow band random noise. This window works on transients or bursts where the signal levels before and after the event are significantly different.

Window

102 MSO2000B and DPO2000B Series Oscilloscopes User Manual

Blackman-Harris

This is the best window for measuring the amplitude of frequencies but worst at resolving frequencies.

4. During play, up to a point, the more you turn the ring, the faster the waveform accelerates. If you turn the ring as far as it can go, the play speed does not change, but the zoom box quickly moves in that direction. Use this maximum rotation feature to replay a portion of the waveform that you just saw and want to see again.

5. Pause the play-pause feature by pushing the play-pause button again.

Searching and Marking Waveforms

You can mark locations of interest in the acquired waveform. These marks help you limit your analysis to particular regions of the waveform. You can mark areas of the waveform automatically, if they meet some special criteria, or you can manually mark each item of interest. You can use arrow keys to jump from mark to mark (area of interest to area of interest). You can automatically search and mark many of the same parameters that you can trigger on.

Search marks provide a way to mark a waveform region for reference. You can set marks automatically with search criteria. You can search for and mark regions with particular edges, pulse widths, runts, logic states, rise/fall times, setup and hold, and bus search types.

To manually set and clear (delete) marks:

1. Move (the zoom box) to the area on the waveform where you want to set (or clear) a search mark by turning the pan

(outer) knob.

Push the next ( →) or previous (←) arrow button to jump to an existing mark.

2. Push Set/Clear.

If no search mark is at the screen center, the oscilloscope will add one.

Analyze Waveform Data

3. Investigate your waveform by moving from search mark to search mark. Use the next ( →) or previous (←) arrow button to jump from one marked location to another, without adjusting any other controls.

4. Delete a mark. Push the next ( →) or previous (←) arrow button to jump to the mark you want to clear. To remove the current, center-positioned mark, push

Set/Clear. It works on both manually and automatically created marks.

To automatically set and clear (delete) search marks:

1. Push Search.

2. Push the Search lower bezel menu and select On.

Save and Recall Information

Save and Recall Information

The oscilloscope provides permanent storage for setups, waveforms, and screen images. Use the internal storage of the oscilloscope to save setup files and reference waveform data.

Use external storage, such as USB flash drives, to save setups, waveforms, and screen images. Use the external storage to carry data to remote computers for further analysis and for archiving.

External File Structure.

If you are saving information to external storage, select the appropriate menu (such as the

To File side-bezel menu to save setups and waveforms) and turn multipurpose knob a to scroll through the external file structure. Drive E is the USB flash drive plugged into the USB Host port on the front of the oscilloscope.

Use multipurpose knob a to scroll through the list of files. Use the Select front panel button to open and close folders.

Naming Your File.

The oscilloscope gives the files it creates a default name in the following format: tekXXXXX.set for individual setup files where XXXXX is an integer from 00000 to 99999; the name is shortened to tXXXXX.set for setup files saved with the Save All function tekXXXXX.png, tekXXXXX.bmp, or tekXXXXX.tif for individual image files; the name is shortened to tXXXXX.png, tXXXXX.bmp, or tXXXXX.tif for image files saved with the Save All function tXXXXYYY.csv for all spreadsheet files or tXXXXYYY.isf for all internal format files

For waveform and for internal format files, the XXXX is an integer from 0000 to 9999. The YYY is the channel of the waveform, and can be one of the following:

CH1, CH2, CH3, or CH4 for the analog channels

D00, D01, D02, D03, and so on through D15 for the digital channels

MTH for a math waveform

RF1 or RF2 for reference memory waveforms

ALL for a single spreadsheet file containing multiple channels when you select Save All Waveforms

NOTE.

Only analog channels and waveforms derived from analog channels (such as math and reference) can be saved to an ISF file. When saving all channels in ISF format, a group of files will be saved. Each will have the same value for XXXXX, but the YYY values will be set to the different channels that were turned on when the Save All Waveforms was performed.

For example, the first time you save a file, that file is named tek00000 for a setup or image file, and t0000 for a waveform or internal format file. The next time you save the same type of file, the file will be named tek00001 or t0001 respectively.

For bus event tables, the XXXX is an integer from 0000 to 9999. The YYY is the type of bus, and can be one of the following:

RS2 (designates RS-232, RS-422, RS-485 or UART buses), I2C, SPI, CAN, or LIN for a serial bus

PAR for a parallel bus
