Quick Tips

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

If you use Autoset when one or more channels are displayed, the instrument selects the lowest numbered channel for horizontal scaling and triggering. You can individually control the vertical scaling of each channel.

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

The A utoset Undo control window remains on the screen until you open another control window. After Autoset Undo closes, you can still undo the last Autoset by selecting the Undo Last Autoset command from the Edit menu. Although the last Autoset is immediately undone, the Autoset Undo control window does not open again.

You can stop the Autoset Undo control window from opening automatically by changing the User Preferences in the Utilities menu.

Acquisition Concepts

Acquisition H

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 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.

Real-time Sampling

In real-time sampling, the instrument digitizes all of the points it acquires using one trigger event. Use real-time sampling to capture single-shot or transient events.

Interpolated Real-time Sampling

In interpolated real-time sampling, the instrument di acquires using one trigger event. If the instrument cannot acquire enough samples for a complete real-time sample rate, it interpolates. Use interpolated real-time sampling to capture single-shot acquisitions.

Interpolation

Your instrument can interpolate between the samples it acquires when it does not have all of the actual samples it needs to ﬁll the waveform record. Linear interpolation computes record points between actual acquired samples by using a straight line ﬁt.

Sin(x)/x interpolation computes record points using a curve ﬁt between the actual values acquired. Sin(x)/x interpolation is the default interpolation mode because it requires fewer actual sample points than linear interpolation to accurately represent the waveform.

Quick Tip

Use the display style Intensiﬁed Samples to intensify the real samples and dim the interpolated samples. (See page 36, Setting the Display Style.)

How the 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.

Acquisition

Average mode calculates the average value for each record point over many acquisitions. Average uses Sample mode for each individual acquisition. Use average mode to reduce random noise.

Waveform Database mode is a three-dimensional accumulation of source waveform data over several acquisitions. In addition to amplitude and timing information, the database includes a count of the number of times a speciﬁc waveform point (time and amplitude) has been acquired.

Pinpoint Triggers

The Pinpoint trigger system also comes with a robust suite of advanced trigger types that is usable on both A and B triggers, and it adds Reset capability to reset the trigger sequence i f the B event does not occur after a speciﬁc number of events or a speciﬁc time. Together, these features support capture of events based on the most complex trigger event or sequence of trigger events.

This section contains concepts and procedures for using the trigger system. Detailed information is available i n the online help.

Triggering Concepts

Trigger Event

The trigger event establishes the time-zero point in the waveform record. All waveform record data are 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 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 (displayed after, or to the right of, the trigger event). Once a trigger is recognized, the instrument will not accept another trigger until the acquisition is complete and the holdoff time has expired.

Trigger Types

Edge trigge trigger event occurs when the trigger source passes through a speciﬁed voltage level in the speciﬁed direction (rising or falling signal voltage).

Pulse triggers are special-purpose triggers that are primarily used with digital signals. The following types of pulse triggers are availa

The serial pattern trigger (available with Option ST) is a special trigger type used on signals with serial data patterns. Serial triggering is available with A triggers only, and only when the Serial option i s present.

odes

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 after a trigger event occurs. If another trigger event is not detected before the timer times out, the instrument forces a trigger. T he length of time it waits for a trigger event depends on the time base setting.

You can also for control window.

ce the instrument to trigger with an edge trigger by clicking the Force Trigger button o n the Trigger Setup

Trigger Holdoff

Trigger holdoff can help stabilize triggering. When the instrument 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. Adjust holdoff to obtain stable triggering when the instrument is triggering on undesired trigger events.

Trigger Coupling

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

coupling only.

Horizontal Po sition

Horizontal position is an adjustable feature that deﬁnes where the trigger occurs on the waveform record. It lets you choose how much the instrument acquires before and after the trigger event. 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 be valuable when troubleshooting. For example, if you are trying 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, if you want 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 instrument 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.

Delayed T

You can trigger with the A (Main) trigger system alone or you can combine the A (Main) trigger with the B (Delayed) trigger to trigger on sequential events. When using sequential triggering, the A trigger event arms the trigger system, and the B trigger event triggers the instrument when the B trigger conditions are met. A and B triggers can (and typically do) have separate sources. The B trigger condition can be based on a time delay or a speciﬁ ed number of events. (See page 33, Using A (Main) and B (Delayed) Triggers.)

Checking Trigger Status

You can check the trigger status from the s tatus lights on the front panel or from the acquisition readout.

Check the ARM, READY, and TRIG’D front-panel controls to determine the trigger status.

If TRIG’D is on, the instrument has recognized a valid trigger and is ﬁlling the posttrigger portion of the waveform.

If READY is on, the instrument can accept, and is waiting for, a valid trigger to occur. Pretrigger data has been acquired.

If ARM is on, the trigger circuitry is ﬁlling the pretrigger portion of the waveform record.

If both TRIG’D and READY are on, a valid A event trigger has been recognized and the instrument is waiting for a delayed trigger. When a delayed trigger is recognized, the posttrigger portion of the delayed waveform will ﬁll.

If ARM, TRIG’D, and READY are off, acquisitions have stopped.

To quickly determine the settings of some key trigger parameters, check the Trigger readout at the bottom of the display. The readouts differ for edge and the advanced triggers.

Spectral Analysis Concepts

Signals may be represented by their characteristics in both the time and the frequency domains. Spectral analysis merges the time domain controls with the frequency domain controls to provide a complete spectral analyzer. Consider the following when using spectral analysis:

Frequency Domain controls use traditional spectrum analyzer controls to set the center frequency, span, and resolution bandwidth directly.

Time Domain controls for the acquired waveform set the time duration and the resolution time between samples. You can easily set the required sample rate and record length.

Gating Controls are the bridge that connects the time domain to the frequency domain. You can perform spectral analysis on a gated region of the input waveform. This gating also determines the resolution bandwidth.

Eight different window functions are a vailable to shape the ﬁlter response.

Display log data i n dB, dBm, or linear mode. You can display the real or only the imaginary parts of the spectral magnitude. Reference level offset and reference level controls give complete control over the vertical position and offset of the spectrum.

Display phase data as a function of frequency in radians, degrees, or group delay. You may zero the phase value for magnitudes below a user-de ﬁned threshold level to prevent the display from becoming unusable due to random noise.

You can turn on averaging in the frequency domain for phase and magnitude waveforms.

Up to four spectral analyzers may be used simultaneously. They may all be assigned to different gates on the same source waveform or to different channel sources. The controls of Math1 and Math2 may be locked, and the controls of Math3 and Math4 may be locked. When controls are locked, turning a control on one analyzer changes the control on the other analyzer to the same value. Other combinations of locking, including all four analyzers, are available using GPIB commands.

Using the Time Controls

The time domain c ontrols for the spectral waveform are:

Duration, which selects the time from the beginning to the end of the acquired waveform. Set duration using the record len

n, which determines the time between samples. Duration is kept constant as resolution is changed. Therefore,

58 TDS6000B & TDS6000C Series Quick Start User Manual

Analyzing Wavef

Using the Gating Controls

Gating determines which portion of the acquired waveform is transformed into the frequency domain. The gate has a position and a width control. The gate position is the time in seconds from the trigger location to the center 50% position of the gate interval. The position and width units are seconds.

Using the Frequency Controls

The frequency domain controls for the spectral waveform are:

Span, which is the frequency at the end of the spectral waveform minus the frequency at the beginning of the waveform.

Center, which is the frequency at the center of the spectral waveform. Center is equal to the start frequency plus one half of the span.

orms

Resolution bandwidth, which is the 3 dB down bandwidth of the spectral analyzer frequency response to a sine wave input.

Using the Magnitude Controls

Vertical units can be either linear or log. When the spectrum is linear magnitude, the vertical units are the same as the source waveform. When the vertical scale of the magnitude spectrum is set to dB, use the Reference Level Offset to set which vertical position in the magnitude spectrum is zero dB. Setting the vertical scale to dBm sets the Reference Level Offset to a value that is equivalent to 1 mW of power into 50 Ω.

The value of the Reference Level is the magnitude at the top of the display screen. Reference Level does not change the spectral data but Reference Level Offset does. Adjusting the Reference Level Offset causes the spectral waveform to move vertically with respect to the waveform reference marker. This moves the waveform without changing the Reference Level control setting.

Using the Phase Controls

You can set the vertical units to Degrees, Radians, or Group Delay in seconds. Phase is a relative measurement that must have a time domain reference point. The phase value is speciﬁed with respect to this phase r eference position.

The spectral analyzer produces phase values from -p to p radians or -180 to 180 degrees. However, when you perform impulse response testing and the phase is continuous, then phase values outside these ranges may occur. The spectral analyzer then wraps the data with discontinuities in the dis play from +180 to -180 degrees. Phase unwrap will display the correct result by unwrapping the phase. P hase unwrap is only valid when the phase spectrum is a continuous function of frequency. Therefore, do not use it when analyzing the harmonic content of the typical repetitive signal.

Random noise in the spectrum may have phase values over the entire range. This could make the phase display unusable. However, you can set the suppression threshold control to a level in dB. The phase of any complex spectral points with a magnitude below this threshold is set to zero.

Using Acquisition Memory to Efﬁciently Capture Multiple High Resolution Events

The r ecord length of an instrument indicates how many sample points the instrument can acquire and store in a single acquisition, while the sample rate determines how closely in time these samples are taken. If you set the oscilloscope to run at the maximum sample rate, then the total time window acquired will be much shorter than if you chose a slower sample rate. In other words, in normal operation the oscilloscope can either acquire a shorter period of signal activity with high resolution or a much longer period of signal activity with lower resolution.

Some applications, such as capturing laser or radar pulses, require that the instrument capture multiple events over a long period of time with very h igh resolution. This example shows you how to use FastFrame to acquire such signals. For this example, we are looking at a laser pulse that ﬁres every 1-2 seconds but is only a few nanoseconds wide. We want to capture 50 consecutive pulses and compare the wave shape of all 50 pulses.

1. Acquire the desired signal on CH1.

Correlating Data Between a Tektronix Oscilloscope and Logic Analyzer

Today almost every design is a high-speed design with fast clock edges and data rates. For these designs, you need to see the analog characteristics of high-speed digital signals in relation to complex digital events in the circuit. iView is your window into the digital and analog world. The iView capability seamlessly integrates and automatically time-correlates data from Tektronix logic analyzers and oscilloscopes, so you can transfer analog waveforms from the oscilloscope to the logic analyzer display with the click of a mouse. View time-correlated analog and digital signals side-by-side and pinpoint the source of elusive glitches and other problems in moments.

The iView External Oscilloscope Cable allows you to connect your logic analyzer to a Tektronix oscilloscope, enabling communication between the two instruments. The Add External Oscilloscope wizard, which is available from the TLA application System menu, will guide you through the process of connecting the iView cable between your logic analyzer and oscilloscope.

A setup window is also available to assist you in verifying, changing, and testing the oscilloscope settings. Before acquiring and displaying a waveform, you must establish a connection between your Tektronix Logic Analyzer and oscilloscope using the Add External Oscilloscope wizard.

1. Select Add iView External Oscilloscope... from the logic

analyzer System menu.
