Recomandare generator de semnal ieftin si bun (max.100Euro)

[dan_e]

Imi puteti recomand un generator de semnal - as vrea de pe aliexpress.com ca sunt mai ieftine (de max.100Euro) - capabil de cativa MHz cel putin, sa mearga bine si la dezvoltarea de surse in comutatie DIY.

Voi ce aveti, ce ati cumparat, cum functioneaza ?

 

Am gasit vreo doua versiuni (care mi s-au parut mie mai... reprezentative):

 

1. Digital DDS Function Generator Dual-channel 12Bits 250MSa/s Sine Wave 24MHz Arbitrary Waveform/Pulse Frequency Signal Generator

mai bine cumpara un osciloscop bun (daca nu ai) generatorul de semnal nu te ajuta cu aproape nimic la sursele in comutatie care se bazeaza marea lor majoritate pe osciloatorul integrat si contollerul PWM din circuitul integrat de control.
