A D –
My old function generator (Thandar TG2001) didnt have the functionality that I needed for repairing old radios etc. I therefore decided to splurge out on a new generator – the Rigol DG832. Only had it for a few days, but very happy with with what it can do. No doubt I will eventually discover what it can do in the fullest of time.
