Siglent Function Generators SDG2042X Editorial Review
The Siglent sdg2042x is a sturdy device that is suitable for sine waves from DC to 40MHz and square up to 25MHz. The frequency has a 7 digit resolution, and the amplitude goes from 1mVp-p to 20Vp-p. It allows you to change impedance to 50 ohm or High Z, and you can mix both outputs internally. It allows you to couple the channels and adjust the phase between channels. It has a function that lets you adjust the amplitude and phase of up to 9 harmonics on that signal. The device supports firmware updates, and when booted, has three options available: (1) reboot to default settings, (2) return to your last setting, and (3) store up to 10 settings that require manual recall. The unit weighs 7.56lbs or 3.43kg and is well-built, which is important to note since some customers received previously used items when they ordered new ones.
