3. Trigger Controls

Trigger type key parameters applicable scenarios

Edge triggered slope (rising/falling), coupling (AC/DC/noise suppression), stable display of conventional signals (sine wave/square wave)

Video trigger standards (NTSC/PAL/SECAM), synchronous (field/line) composite video signal testing, such as television signals

Pulse width triggering conditions (=≠<>), width (33ns-10s), polarity (positive/negative) capture abnormal pulses (such as spikes, narrow pulses)

Trigger mode:

Auto: Automatically scans without triggering, suitable for signal exploration

Normal: Only displayed when triggered, suitable for stable signal observation

Single: Single capture, suitable for transient signals (such as relay arcs)

4. Acquisition Controls

The working principle of the collection mode is applicable to different scenarios

Sampling mode equidistant sampling, 1 sampling point=1 waveform point for most conventional signals

Peak detection mode records the maximum/minimum values within each interval, captures narrow pulses (≥ 10ns), and reduces aliasing

After multiple acquisitions in average mode (4/16/64/128 times optional), suppress random noise and improve signal clarity

Measurement and analysis functions

1. Basic measurement techniques

Voltage measurement:

Peak to Peak Value (Vp-p): The difference between the maximum and minimum values of the signal, calculated by multiplying the number of vertical partitions by volts per grid and the probe attenuation ratio

Amplitude: Voltage from ground to signal peak, for example: 2V/div x 3 zones x 10X probe=60V

Time measurement:

Cycle/frequency: Cycle=number of horizontal partitions x seconds/grid, frequency=1/cycle

Pulse width: time interval at 50% amplitude, rise/fall time: time interval at 10% -90% amplitude

Phase difference measurement: Turn on XY mode and use the Lissajous diagram to determine (for example, when the frequency ratio is 1:1, the straight line is 0 ° and the circle is 90 °)

2. Automatic measurement and FFT analysis

Automatic measurement:

Supports 34 types, including time class (cycle, frequency, delay), amplitude class (peak to peak, overshoot), and count class (pulse number, edge number)

Up to 6 measurement results can be displayed simultaneously, with an update frequency of approximately 2 times per second

FFT analysis:

Window function selection: Hanning window (excellent frequency resolution), flat top window (excellent amplitude accuracy), rectangular window (transient analysis)

Nyquist frequency: half of the sampling rate. Exceeding this frequency will result in aliasing, which needs to be resolved by increasing the sampling rate or filtering

Spectrum measurement: supports cursor measurement of frequency (Hz) and amplitude (dB, 0dB=1VRMS)
