CONTROLS: Rear-panel presets for position, brightness and contrast. Menu controls for brightness and color selection.
GRID STYLES: Single, Dual, Quad, Octal, XY, Single+XY, Dual+XY, and Full Screen -- an enlarged view of each grid style.
GRATICULES: Internally generated; separate intensity control for grids and waveforms. Selectable blending of grid with displayed traces.
WAVEFORM STYLE: Dot-join with optional bold sample point highlight or dots-only.
PERSISTENCE MODES: Color-graded persistence and Analog Persistence, infinite or variable with decay over time. In color-graded persistence, a color spectrum from red through violet is used to map signal intensity. With Analog Persistence, the brightness level of a single color denotes signal intensity. Each trace's persistence data is stored in 64k levels.
TRACE DISPLAY: Opaque or transparent mode, with overlap management.

REAL-TIME CLOCK: Date, hours, minutes, seconds.
EXTERNAL MONITOR: Rear panel 15-pin socket for external VGA compatible monitor.
VERTICAL ZOOM: Up to 5x vertical expansion (50x with averaging, up to 40 µV/div sensitivity).
HORIZONTAL ZOOM: Waveforms can be expanded to 0.4 points/division.
AUTO SCROLL: Use Auto Scroll to automatically "PLAY" the captured signal to identify anomalies quickly and easily. With a selectable zoom expansion and scrolling speed, you can set up Auto Scroll to match your signal viewing needs. The scrolling speed can be adjusted during the scan to focus on the more interesting characteristics of the signal.
"REVERSE" enables you to quickly review any part of the signal.

PERSISTENCE DATA MAP MEMORY: 16 bits per displayed pixel (64k levels).
Up to four processing functions may be performed simultaneously. Functions available are: Add, Subtract, Multiply, Divide, Negate, Identity, Summation Averaging, Sine x/x, Integral, Derivative, Square Root, Ratio, Absolute Value, and the advanced functions listed below.
AVERAGE: Up to 106 averages possible.
EXTREMA: Roof, Floor, or Envelope values from
1 to 106 sweeps.
ERES: Low-Pass digital filters provide up to 11-bit vertical resolution. Sampled data is always available, even when a trace is turned off.
FFT: Spectral analysis with five windowing
functions (Rectangular, Von Hann, Hamming, Flat Top, and Blackman-Harris) and FFT averaging.
STATISTICAL DIAGNOSTICS: The Parameter Analysis package permits in-depth diagnostics on waveform parameters. Live histogramming and trending of any waveform parameter measurement is possible. The histogram can be autoscaled to display the center and width of the distribution. This package is standard on the LC684 and LC584 series and optional on the LC564A.
Note: Any of the above processes can be invoked without losing the data.
WAVEFORM MEMORY: Up to four 16-bit memories (M1, M2, M3, M4).
ZOOM & MATH MEMORY: Up to four 16-bit Waveform Processing memories (A,B,C,D) whose length corresponds to the length of the channel acquisition memory.
SETUP MEMORY: Four non-volatile memories. The floppy drive and optional cards or disks may also be used for high-capacity waveform and setup storage.
The following parametric measurements are available, together with their Average, Highest, Lowest values and Standard Deviation:

PASS/FAIL: Pass/Fail testing allows any five items (parameters and/or masks) to be tested against selectable thresholds. Waveform Limit Testing is performed using Masks that may be defined either inside the instrument or by downloading templates created on a PC. Any failure will cause pre-programmed actions, such as Hardcopy, Save to Internal Memory, Save to mass storage device (card or disk), GPIB SRQ, or Pulse Out.
