Compact Signal Analyzer for Everyday Use
When troubleshooting a circuit feels like searching for a needle in a haystack, you need a reliable tool at your fingertips. This portable analyzer empowers you to quickly diagnose issues and keep your projects on track, available in two tailored models to suit your specific requirements.

With a simple press of the AUTO button, your signal appears instantly on the large, vibrant display. Choose from three methods to capture signals, whether they are stable waveforms or sporadic signals. The Standard model provides 10,000 testing cycles, while the Pro model enhances that to an impressive 50,000 cycles.
Select the version that meets your demands; the Standard captures 5 million snapshots per second, while the Pro model boasts an astounding 48 million snapshots. The Pro is capable of managing signals up to 10 million cycles per second, ideal for laboratory environments, while the Standard handles 1 million cycles for day-to-day testing needs. Both models feature a 2.8-inch display that clearly visualizes waveforms and can safely measure voltages up to 400 volts.

And that's not all! Each model excels with both analog and digital signals, ensuring versatility for any application. Whether you're conducting lessons or repairing devices on-site, these analyzers are designed for portability. Plus, both versions provide up to four hours of continuous operation on a single charge, perfect for extended work sessions.
