LOGIC (Main) -

PATTERN: Specifies a logical combination (AND, OR, NAND, NOR) of the four input channels (high, low, don't care). Trigger when pattern stays true or false for a specified time.

STATE: Any logical pattern of channels 1, 2, and 3 plus a clock edge on channel 4. Triggerable on rising or falling clock edge.

SETUP/HOLD: Trigger on violations of both setup time and hold time between clock and data which are on two input channels.

GLITCH: Trigger on or reject glitches of positive, negative, or either polarity. Minimum glitch width is 1.0 ns (typical), 2 ns (warranted) with 200-ps resolution.

RUNT: Trigger on a pulse that crosses one threshold but fails to cross a second threshold before crossing the first again.

WIDTH: Trigger on width of positive or negative pulse either within or out of selectable time limits (1 ns to 1 s).

SLEW RATE: Trigger on pulse-edge rates that are either faster or slower than a set rate. Edges can be rising, falling, or either.

TIME-OUT: Trigger on an event which remains high, low, or either, for a specified time period, selectable from 1 ns to 1 s, with 200-ps resolution.

VIDEO (Optional) -

Trigger on a particular line of individual, odd/even, or all fields.

Trigger on a specific pixel of a line by using the video trigger with delay by events. Choose positive or negative horizontal sync polarity.

Continuous update of up to four measurements on any combination of waveforms.

Measurement Statistics - Display minimum and maximum or mean and standard deviation on any displayed single-waveform measurement.

Thresholds - Settable in percentage or voltage.

Gating - Any region of the waveform may be isolated for measurement using vertical bars.

Snapshot - Performs all measurements on any one waveform showing results from one instant in time.

Cursor Measurements - Absolute, Delta: Volts, Time, Frequency, and NTSC IRE and line number (with video trigger option).

Cursor Types - Horizontal bars (volts), vertical bars (time); operated independently or in tracking mode.

Waveform Processing

Autoset - Single-button, automatic setup on selected input signal for vertical, horizontal, and trigger systems.

Waveform Limit Testing - Compares incoming or math waveform to a reference waveform's upper and lower limits.

Waveform Histograms - Both vertical and horizontal histograms, with periodically updated measurements, allow statistical distributions to be analyzed over any region of the signal.

Zoom Characteristics

The Zoom feature allows waveforms to be expanded or compressed in both vertical and horizontal axes. Allows precise comparison and study of fine waveform detail without affecting ongoing acquisitions. When used with Hi-Res or Average acquisition modes, Zoom provides an effective vertical dynamic range of 1000 divisions or 100 screens.

Dual Window Zoom - Dual graticules simultaneously show selected and zoomed waveforms. Up to two zoom boxes show areas on the selected trace that are being magnified, and the two magnified areas can be overlapped for quick comparison. Color of zoomed trace matches selected trace.

Display Characteristics

Color - Standard palettes and user-definable color for waveforms, text, graticules, and cursors. Measurement text and cursor colors matched to waveform. Waveform collision areas highlighted with different color. Statistical waveform distribution shown with color grading through variable persistence.

Color Grading - With variable persistence selected, historical timing information is represented by temperature or spectral color scheme providing "z-axis" information about rapidly-changing waveforms.
