Oscilloscope Functions
1. High Bandwidth & Sampling Rate
120MHz bandwidth (single channel) with 250MSa/s real-time sampling rate – captures high-frequency signals accurately.
2. Dual-Channel Input
Two independent channels – compare signals side by side. Bandwidth: 120MHz (CH1 alone) or 60MHz (CH1+CH2 simultaneously).
3. Deep Memory
Up to 128KB record length – captures long signal sequences without losing detail.
4. Multiple Display Modes
Supports YT, XY, and scroll modes – flexible viewing for different measurement needs.
5. Rich Automatic Measurements
Measures frequency, peak-to-peak, average, RMS, amplitude, duty cycle, pulse width, period, max/min, top/bottom values, and negative duty cycle – 14+ parameters.
6. Flexible Trigger Options
Trigger modes: automatic, normal, single. Trigger edge: rising or falling.
7. Bandwidth Limiting
Selectable 20MHz or full bandwidth – reduces high-frequency noise when needed.
8. Afterglow Mode
Options: off, 1 second, or infinite – useful for capturing intermittent or complex signals.
9. One-Key Auto Setup
Automatic waveform optimization on CH1 – speeds up basic measurements.
10. High Input Voltage Protection
x1 probe: <40V; x10 probe: <400V (DC+AC peak) – protects the device from accidental overload.
11. Fast Rise Time
<3ns rise time – responds quickly to fast-edged signals.
