Waveform measurements

System Measurement Rate

The DSA8300 supports up to 8 simultaneous measurements, updated 3 times per second with optional display of per-

measurement statistics (min, max, mean, and standard deviation)

Measurement Set

Over 120 automated measurements include RZ, NRZ, and pulse signal types, and the following measurement types:

Amplitude Measurements

High, Low, Amplitude, Peak-to-Peak, Max, Mid, Min, Mean, +Overshoot, –Overshoot, P-P, Average Optical Power (dBm, watts),

Noise, RMS Noise, SNR, Eye Height, Eye Opening Factor, Extinction Ratio (Ratio, %, dB), Suppression Ratio (Ratio, %, dB),

OMA, Q-factor, RMS, AC RMS, Cycle RMS, Cycle Mean, Gain, Crossing %, Crossing Level OMA, VMA

Timing Measurements

Rise, Fall, Period, Bit Rate, Bit Time, Frequency, Crossing Time, +Cross, –Cross, Jitter (P-P, RMS), Eye Width, +Width, –Width,

Waveform Processing

Up to 8 math waveforms can be defined and displayed using the following math functions: Add, Subtract, Multiply, Divide,

Average, Differentiate, Exponential, Integrate, Natural Log, Log, Magnitude, Min, Max, Square Root, and Filter. In addition,

measurement values can be utilized as scalars in math waveform definitions

Mask Testing

For many applications, standard masks are available as predefined, built-in masks. Many of the most commonly used standard

masks are shown in the following supported standards list. Contact your local Tektronix representative to get a list of all available

masks. Unless otherwise noted, file-based masks are used to distribute new, Tektronix factory-created, updated masks as a file

loadable by the firmware. User-defined masks allow the user to create (through UI or PI) user masks
