Example: Signal Generator Sequencing

This example demonstrates how to use the new SignalGenerator class to create a frequency sweep.

Goal

Generate a signal that steps from 1 GHz to 2 GHz in 100 MHz increments.

The Script

import time
from instrumation.factory import get_instrument

def frequency_sweep():
    # 1. Connect to the Keysight SG
    with get_instrument("TCPIP::192.168.1.50::INSTR", "SG") as sg:

        # 2. Setup initial state
        sg.set_amplitude(-10.0)  # -10 dBm
        sg.set_output(True)

        # 3. Perform the sweep
        for freq in range(1000, 2100, 100):
            actual_freq = freq * 1e6  # Convert MHz to Hz
            print(f"Setting frequency to {freq} MHz...")

            sg.set_frequency(actual_freq)

            # Allow for settling time
            time.sleep(1.0)

        # 4. Cleanup
        sg.set_output(False)
        print("Sweep complete.")

if __name__ == "__main__":
    frequency_sweep()

Why this is better

By using the standardized SignalGenerator interface, this same script will work with any supported signal generator (Keysight, Siglent, etc.) without changing a single line of code.
