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)|
• Simulation (Option SIM) - De-embedding, Embedding,
Random Jitter, Random Noise
Calibrate - classic DCA user interface
All calibrations
• Module (amplitude)
• Horizontal (time base)
• Extinction ratio
• Probe
• Optical channel
Front panel calibration output level
• User selectable –2 V to 2 V

Additional capabilities
Waveform autoscaling
Autoscaling provides quick horizontal and vertical scaling of
both pulse and eye-diagram (RZ and NRZ) waveforms.
Gated triggering
Trigger gating port allows easy external control of data
acquisition for circulating loop or burst-data experiments.
Use TTLcompatible signals to control when the instrument
does and does not acquire data.
