3.10 Waveform Processing
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: Summed averaging up to one million sweeps.
Extrema: Roof, Floor, or Envelope values up to one million 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 four windowing functions 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 auto-scaled to
display the center and width of the distribution. This package is only standard on the
LC584 Series.
Internal Memory
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.
Cursor Measurements
Relative Time: A pair of arrow cursors measures time differences and voltage
differences relative to each other.
Relative Voltage: A pair of line cursors measures voltage differences relative to
each other.
Absolute Time: A cross-hair marker measures time relative to the trigger and
voltage with respect to ground.
Absolute Voltage: A reference bar measures voltage with respect to ground.
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
which 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.
