Basic Operation Guide

1. Installation and functional inspection

Installation requirements: The power cord must comply with the specific specifications of the equipment, with a power supply voltage of 90-264VAC (45-66Hz) or 90-132VAC (400Hz); The equipment is cooled by convection, leaving 2 inches of space at both ends and top.

Functional inspection steps:

After booting up, press the Default Setup button to reset to the factory state;

Connect the TPP0101/TPP0201 probe to channel 1, and connect the probe end/reference wire to the "probe compensation" terminal;

Press AutoSet, and after a few seconds, a square wave of approximately 5V peak to peak and 1kHz will be displayed;

Repeat the operation of channel 2 (check channels 3-4 for 4-channel models) and confirm that all channels are functioning properly.

2. Probe calibration and setting

Probe Inspection Wizard: Press the PROBE CHECK button, and the oscilloscope will automatically verify the probe compensation and attenuation coefficient matching (supporting 1X/10X/20X/50X/100X). If it is qualified, it will display "qualified", otherwise it will prompt correction.

Manual probe compensation:

Channel menu → "Probe" → "Voltage" → "Attenuation" set to 10X, P2220 probe switch adjusted to 10X;

Connect the probe to the "probe compensation" terminal and display a square wave according to AutoSet;

Adjust the probe compensation screw until the waveform is "compensated correctly" (no overcompensation/overcompensation).

Current probe settings: Channel menu → "Probe" → "Current" → "Ratio", default 10A/V, need to match the ratio of the current probe.

3. Core control operations

(1) Vertical control

Coupling: DC (AC/DC), AC (DC blocking, attenuation<10Hz signal), grounding (disconnected input);

Bandwidth limit: 20MHz bandwidth limit can be enabled to reduce high-frequency noise;

Scale and Position: The "Vertical Scale" knob adjusts the voltage/grid (1-2-5 sequence, fine adjustment can set small steps), and the "Vertical Position" knob moves the waveform up and down.

(2) Horizontal control

Time base range: 5ns-50s/grid (1-2.5-5 sequence), corresponding relationship of sampling rate is as follows (partially):

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

5.0ns-250.0ns 1 GS/s 150.0 MHz

500.0ns 500.0 MS/s 150.0 MHz

1.0μs 250.0 MS/s 125.0 MHz

Window function: Open the "Window Settings" through the "Horizontal Menu", define the waveform segment and zoom in to view, supporting switching between the main time base and window view.

(3) Trigger control

Trigger type:

Edge trigger: rising/falling edge, optional source of CH1/CH2/ext/ext/5/mains power, coupling supports DC/AC/noise suppression, etc;

Video trigger: Supports NTSC/PAL/SECAM standards, synchronizes optional scan lines/line numbers/odd fields/even fields/all fields;

Pulse width triggering: The triggering conditions are=(± 5% tolerance), ≠,<,>, and the pulse width range is 33ns-10s.

Key buttons: "Set to 50%" (trigger level set to signal midpoint), "Force trigger" (complete acquisition regardless of trigger conditions), "Trig View" (hold down to view trigger signal).

Functional applications and examples

1. Signal measurement

(1) Automatic measurement

Supports 16 measurement types, with a maximum of 5 displayed at once. Some types are defined as follows:

Measurement type definition applicable scenarios

Frequency measurement, first cycle calculation, frequency cycle signal frequency detection

Measurement of the amplitude range of the absolute difference signal between the maximum and minimum peak values of the peak to peak waveform

Evaluation of edge velocity of time pulse signal between 10% -90% rising edge of rising time waveform

Synchronization analysis of phase difference signal between rising edges of two channel phase signals

Determination of pulse signal symmetry based on the proportion of duty cycle, positive pulse time, and period

Operation steps: Press the Measure button → Select the source → Select the measurement type → View the reading (including real-time updates).

(2) Cursor measurement

Type: Time cursor (vertical line, measuring time/frequency/amplitude), amplitude cursor (horizontal line, measuring voltage/current);

Example: Measure pulse width → Press cursor → Select "time" from "type" → Move cursor 1/2 to the rising/falling edge of the pulse → Read and display Δ t (pulse width).

2. Advanced analysis function

(1) FFT analysis

Function: Convert time-domain (YT) signals into frequency-domain spectra, supporting 1024 data points (0Hz Nyquist frequency);
