Basic Operation Guide

1. Device initialization and probe settings

(1) Power on and self-test

After turning on, the oscilloscope automatically performs a self-test. If it displays "PASS", it is normal; If "FAIL", check the power connection or contact for repair;

Press the Default Setup button to quickly reset to factory settings (vertical coupling DC, trigger edge rise, time base 200ns/grid).

(2) Probe connection and compensation

Probe selection: It is recommended to use Tektronix specialized probes, such as P6139A (100MHz/10X) and P6249 (500MHz/10X);

Connection steps: ① Connect the BNC end of the probe to the oscilloscope channel, ② Connect the probe tip to the measured signal point, ③ Connect the reference wire to the circuit ground;

Manual compensation: ① Connect the probe to the "probe compensation" terminal (output 5V/1kHz square wave), ② Display the waveform according to AutoSet, ③ Rotate the probe compensation screw until the waveform is free of overshoot/undershoot (standard square wave);

Attenuation setting: Channel menu ->"Probe Attenuation" Set to 1X/10X, which should match the actual attenuation ratio of the probe (default 10X).

2. Core control system operation

(1) Vertical system

Coupling mode:

DC: AC/DC signal, suitable for DC bias signals (such as power supply voltage);

AC: Block DC components (attenuation<10Hz signal), suitable for AC signals (such as audio);

Grounding: Disconnect the input to determine the zero level position;

Vertical Scale: Range 2mV-10V/grid (1-2-5 sequence), adjustable through the "Vertical Scale" knob; Support "fine adjustment" mode (switch by knob), achieve non-standard stepping (such as 2.5mV/grid);

Channel control: Press the channel button (CH1/CH2, etc.) to turn on/off the channel, move the "vertical position" knob up and down to display the waveform, and support channel overlay display (press Display → "Overlay").

(2) Horizontal system

Time base range: 5ns-50s/grid (1-2-5 sequence), corresponding to the following sampling rate relationship (taking TDS3052B as an example):

Time base setting sampling rate maximum measurable frequency (Nyquist frequency)

5ns-200ns 5GS/s 2.5GHz

400ns-1μs 2.5GS/s 1.25GHz

2μs-50s 1GS/s 500MHz

Sampling mode:

Real time sampling: suitable for high-frequency signals (≤ bandwidth), directly capturing signals;

Equivalent sampling: suitable for ultra-high frequency signals (>bandwidth), reconstructing waveforms through multiple samplings;

Window function: Press Horiz Menu → "Window" to open, define waveform segments and zoom in to view, support switching between main timing and window view.

(3) Trigger system

Trigger type:

Edge trigger: Based on the rising/falling edge of the signal, the source can be selected as CH1-CH4/Ext/Ext 5x/mains power; Coupling supports DC/AC/noise suppression (reducing false triggering of high-frequency noise);

Video trigger: Supports NTSC/PAL/SECAM standards, with synchronization methods including all fields/odd fields/even fields/specified number of lines (1-525 NTSC, 1-625 PAL);

Pulse triggering: triggered by pulse width (20ns-10s), with conditions of>,<,=, ≠, suitable for abnormal pulse detection (such as burrs);

Code triggering: triggered based on logical combinations of 2-4 channels (such as CH1=high, CH2=low), supporting TTL/CMOS levels;

Key operation: Press Set to 50% to automatically set the trigger level to the midpoint of the signal peak to peak; Press Force Trigger to ignore triggering conditions and force collection.
