| Case | Input Basis | Key Values | Base PPS | Effective PPS |
|---|---|---|---|---|

| Clock source | Frequency | 500 Hz | 500.000 | 500.000 at unity correction |
| Timing probe | Period | 2 ms | 500.000 | 475.000 at 95% efficiency |
| Encoder wheel | Speed / spacing | 3 m/s and 0.02 m spacing | 150.000 | 153.000 with 1.02 correction |

Count mode: PPS = Pulse Count ÷ Observation Time
Frequency mode: PPS = Frequency in hertz
Period mode: PPS = 1 ÷ Period in seconds
Spacing mode: PPS = Speed ÷ Pulse Spacing
Burst mode: PPS = Pulses per Burst × Bursts per Second
Corrected PPS: Base PPS × Correction Factor
Effective PPS: Corrected PPS × Efficiency ÷ 100
Period: 1 ÷ Effective PPS
High Time: Period × Duty Cycle ÷ 100
Low Time: Period − High Time
Uncertainty band: Effective PPS ± (Effective PPS × Uncertainty ÷ 100)
Pulses per second measures how many repeating signal events occur during one second. In many physics and electronics problems, it is numerically identical to frequency in hertz.
Yes, when one pulse represents one complete event each cycle. If your system emits several pulses per cycle, convert carefully by linking pulse count to the actual physical cycle definition.
Count and time mode is useful for experimental measurements. You can observe pulses over a real interval, then divide count by time to get an average PPS value.
Duty cycle does not change the raw pulse rate. It splits the computed period into high-time and low-time portions, which helps when analyzing digital timing or gating behavior.
Burst mode helps when signals arrive in grouped packets instead of evenly spaced pulses. Multiply pulses inside each burst by bursts occurring each second to estimate average PPS.
The correction factor scales the base PPS value for calibration, instrument bias, gearing, sensor mapping, or any known proportional adjustment required by your measurement system.
Uncertainty gives a lower and upper PPS range around the effective value. That is useful when timing measurements, sensor counts, or spacing estimates are not perfectly exact.
Yes. After calculating, use the CSV button for spreadsheet-friendly data or the PDF button for a quick formatted report you can archive, email, or print.
