Acquisiti

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.

on Hardware

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 S ampling

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.

Equivalent-Time Sampling

The instrument uses equivalent-time sampling t its r eal-time maximum sampling rate. Equivalent-time sampling is only used if Equivalen base is set to a sampling rate that is too fast to create a waveform record using real-time sampling

The instrument makes multiple acquisitions of a repetitive waveform to obtain the sample density record. Thus, equivalent time sampling should only be used with repetitive signals.

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.

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 only works with real-time, noninterpolated sampling and is useful for catching high frequency gl

Hi Res mode calculates the average of all the sa interval. Hi-Res provides a higher-resolution, lower-bandwidth waveform.

Envelope mode ﬁnds the highest and lowest record points over many acquisitions. Envelope uses Peak Detect for each individual 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 comes with advanced trigger types that are usable on both A and B triggers, and it can reset the trigger sequence if the B event does not occur after a speciﬁc number of events or a speciﬁc time. Pinpoint triggers 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.

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. T he instrument continuously acquires and retains enough sample points to ﬁll the pretrigger portion of the waveform record. 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 Modes

The trig

Normal t waveform record acquired remains on the display. If no last waveform e xists, 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

Auto mo display. The waveform will appear to roll across the screen. If valid triggers occur, the display will become stable.

In edge-trigger mode, you can also force the instrument to trigger by pushing the Force Trigger button on the Trigger Setup control window.

Select the trigger mode in the Trig > Mode menu. For more information, see the instrument online help.

Trig

Trigger holdoff can help stabilize triggering, by extending the period in which further trigger recognition is suppressed after initiating an acquisition. Such an extension can help the system skip over the remaining events of a recurring burst of events, and thus always trigger on the ﬁrst event in each burst. Adjust holdoff to obtain stable triggering when the instrument is triggering on undesired trigger events.

Set the trigger holdoff in the Trig > Holdoff menu. For more information, see the instrument online help.

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.

Select the trigger coupling in the Trig > A Event (Main) Trigger Setup menu. For more information, see the instrument online help.

Horizontal Position

Horizontal position deﬁnes where the trigger occurs on the waveform record. It lets you choose how much the instrument acquires be part that occurs after the trigger is the posttrigger portion.

Pretrigger data can be valuable when troubleshooting. For e xample, 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 Alternatively, if you w ant 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.

analyzing what happens before the glitch, you may uncover information that helps you ﬁnd the source of the glitch.

Slope an

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.

d Level

Delayed Trigger System

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

er event triggers the instrument when the B trigger conditions are met. A and B triggers can (and typically do) have

trigg separate sources. The B trigger condition can be based on a time delay or a speciﬁed number of events. (See page 53, Using A (Main) and B (Delayed) Triggers.)

Checking Trigger Status

You can check the trigger status from the status lights on the front panel or from the 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.

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 jump from mark to mark (area of interest to area of interest). With the Advanced Search and Mark option, you can automatically search and mark m any of the same parameters that you can trigger on. Many search parameters don’t have the time limits as triggers. You can search on math and reference waveforms. You can ﬁnd all of the acquired events of a certain type.

Search marks provide a way to mark a waveform r egion 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 violations, and bus search types.
