Oscilloscope
I recently purchase a small single change digital oscilloscope. Typical for Chinese supply the instruction provided are terse. These are some additional notes.
Measurement options:
| Type | Display | Description | Unit |
|---|---|---|---|
| Freq | Frq | Frequency | Hz |
| PKPK | PKPK | Peak to Peak Voltage | Volts |
| Mean | Mea | Mean Voltage | Volts |
| RMS | RMS | Root Mean Square Voltage | Volts |
| Amp | AMP | Amplitude, the voltage between signal peak voltages | Volts |
| Duty | Duty | Duty cycle (percentage of time +) | % second/second |
| Wid+ | (T+) | Period of the signal + | seconds |
| Wid- | (T-) | Period of the signal - | seconds |
| Perd | T | Period of signal | seconds |
| Max | MAX | Minimum voltage | Volts |
| Min | MIN | Maximum voltage | Volts |
| Top | TOP | Top + voltage | Volts |
| Base | Bas | Lowest - Voltage | Volts |
| Duty- | Dut- | Duty cycle - (percentage of time -) | % second/second |
