Siglent SDG1032X
The Siglent SDG1032X is what engineers reach for when signal quality matters. The spectral purity on the sine output is measurably better than cheaper generators — you'll see it on your spectrum analyzer. IQ baseband output is unusual at this price and invaluable for RF work. The best under-$300 generator you can buy.

What We Like
- ✓Spectral purity on sine output is measurably better than cheaper generators
- ✓IQ baseband output for RF hobbyists working with SDR and modulation
- ✓16K arbitrary waveform points — 4x more than most competitors
- ✓EasyWave PC software is the best in class for waveform creation
- ✓LAN control enables remote operation and automation
Limitations
- ✗$299 is the highest price in our comparison — hard to justify for casual use
- ✗30MHz max frequency means it needs pairing with an RF generator for VHF+ work
- ✗Large footprint — occupies significant bench space
