A simple GUI for monitoring waveforms.

Wave Monitor

A simple GUI for monitoring waveforms. It plots waveforms with PyQtGraph in a separate process.

The WaveMonitor class is the primary Python API.

In the GUI, right click to show the menu. Keyboard shortcuts are also supported.

Installation

pip install WaveMonitor

Usage

from wave_monitor import WaveMonitor
import numpy as np

monitor = WaveMonitor()
monitor.autoscale()
monitor.clear()

t = np.linspace(0, 1, 1_000_001)  # 1m pts ~= 1ms for 1GSa/s.
n = 20
i_waves = [np.cos(2 * np.pi * f * t) for f in range(1, n + 1)]
q_waves = [np.sin(2 * np.pi * f * t) for f in range(1, n + 1)]

for i, (i_wave, q_wave) in enumerate(zip(i_waves, q_waves)):
    monitor.add_wfm(f"wave_{i}", t, [i_wave, q_wave])
monitor.autoscale()

monitor.add_wfm("wave_1", t, [i_waves[-1], q_waves[-1]])  # Replaces previous wfm.
monitor.add_note("wave_1", "re-writen")

monitor.remove_wfm("wave_10")
