Automated frequency response measurements of filters, amplifiers, and feedback loops. The -S models include a signal generator. This option activates Bode plot analysis using that generator as the stimulus source. The option is enabled by a software license keyed to the oscilloscope's serial number and is permanent for the life of the instrument. Key Features Automated Bode Plot — Define frequency range and stimulus amplitude. Oscilloscope sweeps, measures, and plots gain and phase. Uses Built-In Generator — Works with the signal generator already in your -S model. No external equipment. Filter/Amplifier Characterization — Verify cutoff, roll-off, passband flatness, and bandwidth. Loop Stability — Measure gain and phase margin for power supply feedback loops. Lifetime License Activation — activate once, owned for the life of the instrument. No subscriptions, no renewals, no maintenance fees. When You Need This Option The option fits the following workflows: Power Supply Loop — Verify feedback loop stability with automated gain/phase margin measurement. Active Filter — Confirm Butterworth/Chebyshev filter meets cutoff and roll-off specs. Compatibility This option is compatible with MSO2000 -S model oscilloscopes with built-in signal generator. The same capability is offered on other UNI-T oscilloscope families: MSO3000CS. Frequently Asked Questions Do I need a -S model? Yes. Bode plot uses the built-in signal generator as stimulus. Only -S models have the generator. How is this option activated? The option is enabled by a software license keyed to the oscilloscope's serial number. After purchase, the license is registered on the UNI-T website to generate the license file, which is then loaded onto the instrument from a USB drive through the option-install menu. Refer to the oscilloscope's user manual for the step-by-step procedure. Is the license permanent, or does it require renewal? The license is permanent — a one-time purchase that stays active for the life of the instrument. No subscriptions, no annual renewals, and no expiration.
