제품특징
RK1212 series Audio signal generator
Product introduction
Rk1212 series audio signal generator uses the advanced voltage-controlled oscillation circuit,it can produce stable,low distortion sine wave signal.The output amplitude frequency with digital display,sweep frequency range can reach more than 1:1000,the beginning and the end point of the sweep frequency can be set arbitrarily,and with the delay output,short circuit protection and other functions,it also design and test any "positive" and "negative" polarity function of type,size,impedance loudspeaker,headset,moving coil receiver.
Application area
This instrument can generate the audio signal for the acoustic audiometry,and can distinguish the positive (negative) polarity of horn and the pure tone index of speaker rapidly and accurately.The operation is simple,and it widely used in acoustics,telecommunications and other aspects,especially for loudspeaker production and sound box manufacturing factory.
Performance characteristics
Ultra strong over current protection,short circuit protection
The range of signal frequency:20Hz—20kHz
3/4 bits voltage and frequency display simultaneously.
The starting and end point of sweep frequency and time of sweep frequency set according to the requirement.
Unique and reliable audio power amplifier design.
RK1212BL+ not only have all the function of RK1212BL,but also with the function of polarity measurement of the speaker/microphone.
