Maximum SSC Frequency (kHz) - When the 'Data Standards' selection is "Custom", this in combination with
Minimum SSC Frequency, determines the SSC frequency range over which the tool will search for the maximum
SSC ppm deltas.
Measure Bit Rate (Mb/s) - Measures the Bit Rate based on a correctly defined pattern. The bit rate is derived by
measuring the total time over a number of pattern repeats and calculating an ideal unit interval.
Measure Edge Count - Enter a number of edges to skip on the measured edge(s) relative to the arm time. Typically,
skews would be measured on edges consecutive to the Reference, so the Ref Edge count and Meas Edge count
would be equal.
Measure Incr (Periods) - Choose the increment step size of the number of cycles to measure.
Measure RJ + PJ Per- – Plots RJ + PJ time measurements for Period - (falling edges to falling edges). See Measure
RJ + PJ Per+. See also High Frequency Modulation Theory.
Measure RJ + PJ Per+ – Plots RJ+PJ time measurements for Period + (rising edges to rising edges). See Measure
RJ + PJ Per-. See High Frequency Modulation Theory.
Measure RJ + PJ PW- – Plots RJ + PJ time measurements for PW- (pulse width falling edges to rising edges).
Measure RJ + PJ PW+ – Plots RJ + PJ time measurements for PW+ (pulse width rising edges to falling edges).
Measurement - Select primary measurement configuration for the unit: Rise time, Fall time, PW+, PW-, Period
+ and Period - -.
Minimum Data Points - Determines the number of time measurements shown on Time View and refers to the
number of hits in the histogram. Directly affects FFT resolution. A larger value results in greater FFT resolution
and the ability to see lower frequencies.
Minimum Delay (ns) - Sets time delay between reference clock edge and data edge allowing different data edges to
be measured. Due to the measurement technique, the closest data edges to a clock reference edge are captured. An
oscilloscope has an inherent trigger delay. This value corresponds to the trigger delay on an oscilloscope.
