Portable 3-Channel Signal Analyzer Phase/Spectrum/Harmonic Analysis Tool Phase Difference Detection Module

Introduction:
- It is a portable signal analysis tool designed for research and development, debugging, and on-site measurement.
- Real three channel synchronous acquisition, direct viewing of waveforms on the screen, and further recording and analysis on the computer.
- CH1 yellow: three channel synchronization
- CH2 blue: three sets of phase difference
- CH3 red: spectral analysis
- Yellow, blue, and red correspond to three input channels; the screen displays real time frequency, Vpp, phase and battery status.

Applications:
- Power and inverter output inspection
- Verification of three-phase signal and phase relationship
- Filter, amplifier, sensor debugging
- Rapid investigation of laboratory waveforms, spectra, and harmonics

Core Functions:
- Three-channel synchronous acquisition: CH1/CH2/CH3 independent input, clear color correspondence: yellow, blue, red.
- Three sets of phase difference measurement: directly view the phase differences of CH1-CH2, CH1-CH3, and CH2-CH3.
- Spectrum and harmonic analysis: 256 point waveform, 256 point spectrum, supporting 1-5 order harmonics and THD display.
- Automatic gain and sampling rate: PGA113 multi level gain, supports AUTO; The sampling rate supports both AUTO and manual selection.

Operation Steps:
1. Signal Connection: Connect the measured signal to CH1, CH2, CH3, and keep the signal source and device grounded.
2. Interface Selection: Use the directional keys to select OSC/Spec/Harm on the right side, and press OK to confirm.
3. Parameter Adjustment: Select the sampling rate and set the CH1-CH3 gains separately; AUTO mode can automatically track.

Specifications:
- CH1: ADC1_IN0/PA0
- CH2: ADC2_IN2/PA2
- CH3: ADC3_IN3/PA3
- PGA113-C: PD13=SCLK·PD14=DIO·PD15=CS
- Gain level: x1/x2/x5/x10/x20/x50/x100/x200/AUTO/GND
- Display: 320x240 color LCD; Data: waveform, spectrum, phase, harmonic, THD, Vpp
