Internal analysis of handheld oscilloscopes
Capture method
Peak detection - every two sampling cycles as a peak detection cycle, sampling the maximum and minimum values within the cycle, as a sampling point, the composition of the waveform. This capture method is applied to capture high frequency and random burrs. Burrs as narrow as 10ns can be captured at all time divisions from 5μs/div to 5s/div.
Sampling - Sample data at equal time intervals.
Averaging-Average 2 to 512 (optional) captured waveform data.
Envelope-Maximum/minimum values obtained on one or more captured signals.
Trigger system
1, the main trigger mode - automatic (support 0.5s/div and slower scrolling mode), normal.
2, trigger type
Edge-conventional level-driven trigger. Positive or negative slope on any channel. Coupling options: DC, noise suppression, high frequency suppression, low frequency suppression.
Pulse Trigger-
External Trigger-Supports 5MHz TTL level, selectable 200mV to 2V trigger level;
Video - selectable triggering on Field or Lines of video, triggering on NTSC, pAL or SECAM broadcast standard video;
Motor Trigger: Trigger on 3 and 5 level pulse width modulated power signals, this feature is only used in THS720p.
3, trigger source: any channel, external trigger channel, external trigger channel / 5, mains power;
4, trigger display: can display the trigger level;
5, cursor system:
Type: horizontal line, vertical line, paired line;
Cursor measurement: ΔVolt, Δtime, 1/Δtime (Hz), degree (phase).
Time base system
1,Horizontal zoom: Horizontal zoom in or zoom out of static or dynamic waveforms, you can use the viewport to select a specific area for the window expansion mode to zoom in and out of the observation.
2,Time/division range：-5ns～5s/div;
3,Record length: 2500 points;
4, horizontal accuracy: ± 0.01%;
5,Time base stability: 200ppm.
Measurement system
1,Automatic waveform measurement-Automatic measurement of 21 parameters: period, frequency, positive pulse width, negative pulse width, positive overshoot, negative overshoot, high value, low value, maximum, minimum value, peak-peak, amplitude, average value, average value of the period, the root mean square, the root mean square of the period, the rise time, the fall time, the positive duty cycle, the negative duty cycle, the width of the outburst, and can display the four arbitrary combinations of the waveform Measured value.
2, thresholds - can be set by percentage or voltage of various thresholds, such as, rising edge from 10% to 90% (or 0.1V to 0.9V)
3,Calculation calculator-add, subtract, multiply and calculate the U x I power value;
