Configure measurements

– Thresholds

– 10%, 50%, 90% or 20%, 50%, 80% or custom

– 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” measure-

ments 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)

Measurements (Continued)

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)

– Simulation (Option SIM) — De-embedding, embedding,

random jitter, random noise
