Interpolation
Your instrument can interpolate between the samples it acquires when it does not have all of the actual samples it needs to ll the waveform record. Linear interpolation computes record points between actual acquired samples by using a straight line t.
Sin(x)/x interpolation computes record points using a curve t 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 Intensied Samples to intensify the real samples and dim the interpolated samples. (See page 36,

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

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 specic number of events or a specic 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. The instrument continuously acquires and retains enough sample points to ll 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 trigger
Auto mode, w 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 with an edge trigger by clicking 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.
Trigger Ho
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.
Set the trigger holdoff in the Trig > Holdoff menu. For more information, see the instrument online help.
mode determines how the instrument behaves in the absence of a trigger event:
Normal trig 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 tri

Trigger Coupling
Trigger coupling determines what part of the signal is passed to the trigger circuit. Edge triggering can use a ll 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 Po sition
Horizontal position denes where the trigger occurs on the waveform record. It lets you choose how much the instrument acquires bef part that occurs after the trigger is the posttrigger portion.
Pretrigger data can be valuable when troubleshooting. For example, if you are trying to nd 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 an 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.

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 trigger ev separate sources. The B trigger condition can be based on a time delay or a specied number of events. (See page 31, 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 ll ing 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 lling 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 i nstrument is waiting for a delayed trigger. When a delayed trigger is recognized, the posttrigger portion of the delayed waveform will ll.
If ARM, TRIG’D, and READY are off, acquisitions have stopped.

Quick Tips
Sources for spectral math waveforms must be channel or other math waveforms.
Use short record lengths for faster instrument response.
Use long record lengths to lower the noise relative to the signal and increase the frequency resolution.
Different window functions produce different lter response shapes in the spectrum and result in different resolution bandwidths. See the online help for more information.
The resolution bandwidth (RBW) directly controls the gate width. Therefore, the time domain gate markers move as you adjust the control.
You can display the linear magnitude of the real data or the imaginary data in the spectrum. This is useful if y ou process the spectrum off line and transform it back into a time domain trace.
