Operating Guide

1,the selection key (Select) to select the position of the cursor is operable to change the signal frequency, duty cycle , etc. ;
2,waveform buttons (Wave) is used to change the current output signal waveform types , which corresponds to a sine wave SIN , SQR corresponding square wave , TRI corresponding triangle wave ;
3,when adjusting the frequency, duty cycle values ​​, increase button ( + ) and decrease ( - ) button is used to add and subtract numerical operations ;
4,sweep button (Sweep) Sweep function interface for entering into a detailed description see below ;
5,the OK button (Set) is used to eliminate the cursor ;
6,OFFSET potentiometer for adjusting the output signal of the DC bias ;
7,AMPL potentiometer for adjusting the magnification of the output signal ;
8,TTL toggle switch is used to synchronize the same frequency TTL output waveform ;
9,Power_Selet switch for switching power supply (USB power and external power supply ) .
