Audio Sweep Signal Generator Speaker Tester Frequency Sweep Meter 20Hz-20KHz 0-12.8Vrms 20W TH1312-20

Description:
TH1312-20 is a 3 3/4 digit Audio Sweep Signal Generator with sine wave output, low distortion and high stability over the whole audio frequency range
The start and end sweep frequencies and sweep time can be set as you need and signal frequency will be outputted by automatic log sweep mode or manual adjustment mode
TH1312-20 has multi protective functions such as power on/off delay protection, over current protection and DC amplitude limit protection, long time short circuit is permitted and this character makes the instrument more reliable and convenient, three different kinds of power outputs can be selected
TH1312-20, with its good load regulation and smooth amplitude frequency characteristics, can be widely used as a signal generator in acoustical, oscillatory and telegraphic areas
The production is especially suitable for purity inspection of loudhailer unit and system (sound box)
