–– Eye boundaries
–– Define boundaries for eye measurements
–– Define boundaries for alignment
–– Format units for
–– Duty cycle distortion — Time or percentage
–– Extinction/Contrast ratio — Ratio, decibel or percentage
–– Eye height — Amplitude or decibel (dB)
–– Eye width — Time or ratio
–– Average power — Watts or decibels (dBm)
–– Top base definition
Automatic or custom
–– Δ time definition
–– First edge number, edge direction, threshold
–– Second edge number, edge direction, threshold
–– Jitter mode
–– Units (time or unit interval, watts, volts, or unit amplitude)
–– Signal type (data or clock)
–– Measure based on edges (all, rising only, falling only)
–– Graph layout (single, split, quad)
Quick measure configuration
When using the classic DCA interface, “Quick Measure”
measurements are initiated by pressing the <Multi-Purpose>
button on the front panel.
–– Four user-selectable measurements for each mode, eye-
mask, TDR, etc.
–– Default settings (Eye/Mask mode) extinction ratio, jitter RMS,
average power, crossing percentage
–– Default settings (Oscilloscope mode) rise time, fall time,
period, V amptd
Histograms
Configure
–– Histogram scale (1 to 8 divisions)
–– Histogram axis (vertical or horizontal)
–– Histogram window (adjustable window via marker knob)
Math measurements - classic DCA user interface
–– Four user-definable functions operator — Magnify, invert,
subtract, versus, min, max
–– Source — Channel, function, memory, constant, response
(TDR)
Signal processing measurements - FlexDCA
–– Math — Add, subtract, multiply, average, invert, maximum,
minimum, median
–– Signal processing — Difference (differentiate), summation
(integrate), interpolation (linear, Sin(x)/x), filters: 4th order
bessel, butterworth, gaussian
–– Transforms — FFT, versus
–– Equalizer (Option 201) — Linear feed-forward
–– Equalizer (LFE, up to 64 taps)
