The novel RC oscillating sweep frequency technology is adopted, and the sine wave distortion is small, which is especially suitable for hearing the pure tone of loudspeakers.
A 5-digit nixie tube displays the frequency value.
DF1212BL uses a 4-digit digital voltmeter to indicate the output amplitude value, and other models use a pointer voltmeter.
The starting point and end point of the frequency sweep can be adjusted at will.
High output power, up to 200W.
There is a synchronous output terminal.
