| Acquisition Modes |
| DPO | Captures and displays complex waveforms, random events and subtle patterns in actual signal behavior. DPOs are able to provide 3 dimensions of signal information in real time: Amplitude, time and the distribution of amplitude over time. |
| Peak Detect | High frequency and random glitch capture. Captures glitches as narrow as 1 ns. |
| WaveAlert | Monitors the incoming signals on all channels and alerts the user to any waveform that deviates from the normal waveform being acquired. |
| Sample | Sample data only. |
| Envelope | Max/min values acquired over one or more acquisitions. |
| Average | Waveform data from 2 to 512 (selectable) acquisitions is averaged. |
| Single Sequence | Use the Single Sequence button to capture a single triggered acquisition sequence at a time. |
| Trigger System |
| Main Trigger Modes | Auto (supports Roll Mode for 40 ms/div and slower), Normal. |
| B Trigger | Trigger after time or events. |
| Trigger After Time Range | 13.2 ns to 50 s. |
| Trigger After Events Range | 1 to 9,999,999 events. |
| External Trigger Input | >1 Megaohm in parallel with 17 pF; Max input voltage is 150 VRMS. |
| Trigger Types |
| Edge | Conventional level-driven trigger. Positive or negative slope on any channel. Coupling selections: DC, noise reject, HF reject, LF reject. |
| Video | Trigger on all lines or individual line, odd/even or all fields or analog HDTV formats (1080i, 1080p, 720p, 480p). See optional TDS3VID and TDS3SDI application modules for extended video triggering and measurement features. |
| Logic (requires TDS3TRG) | PATTERN: Specifies AND, OR, NAND, NOR when true or false for a specific time.
STATE: Any logic state. Triggerable on rising or falling edge of a clock. Logic triggers can be used on combinations of 2 inputs (not 4). |
| Pulse (requires TDS3TRG) | WIDTH (or GLITCH): Trigger on pulse width less than, greater than, equal to or not equal to a selectable time limit ranging from 39.6 ns to 50 s.
RUNT: Trigger on a pulse that crosses one threshold but fails to cross a second threshold before crossing the first again.
SLEW RATE: Trigger on pulse edge rates that are either faster or slower than a set rate. Edges can be rising, falling or either. |
| Comm (requires TDS3TMT) | Provides isolated pulse triggering required to perform DS1/DS3 telecommunications mask testing per ANSI T1.102 standard. |
| Alternate | Sequentially uses each active channel as a trigger source. |
| Measurement System |
| Automatic Waveform Measurements | Period, Frequency, +Width, -Width, Rise Time, Fall Time, +Duty Cycle, -Duty Cycle, +Overshoot, -Overshoot, High, Low, Max, Min, P-P, Amplitude, Mean, Cycle Mean, RMS, Cycle RMS, Burst Width, Delay, Phase, Area*1, Cycle Area*1.
