Mode 6: 256 points waveform display mode
Mode 7: 128 points waveform +128 frequency division with peak holding
Mode 8: 128 points waveform +128 frequency division without peak holding
Key and Power Switch:
K1: mode switching, with power-off memory
K2: switch between MIC and LIN input, with power-off memory
Power Switch: push down to turn on
Input adjustment potentiometer: for adjusting the input signal, for example, the input signal can be attenuated if it is too strong, or adjust this potentiometer to shield some equipments which have strong background noise.(clockwise to increase)
Spectral display amplitude potentiometer: for adjusting the maximum display amplitude after AGC (Automatic Gain) process. After setting, the automatic gain will take this setting value as the maximum amplitude to adjust automatically. (clockwise to increase)
Audio terminal input adopts 3.5mm male headphones, connect it to computer headphone output interface via the audio branch, the other end of the branch connects external audio equipment. Please check whether the audio cable or branch has good contact if the audio has noise or the spectrum has background noise under mute and MIC off mode when using.
