- Page 3 Operating Guide Pressing the “select” button which can switch from frequency adjusting to function adjusting, and the detailed condition (frequency adjusting or function adjusting) displayed after “*”. As frequency adjusting, pressing the button of “left” and “right” can adjust position, and the “OK” button can switch units(Hz，kHz and MHz) and then adjust the code switch and the corresponding value of frequency appear.
- Page 4 As function adjusting, pressing the button of “left” and “right” can switch “WAVE，“DUTY”， “COUNTER”， “EXT.FREQ”， “SAVE” , “LOAD”, “TIME” and “SWEEP”. As WAVE adjusting, pressing “OK” which can change waves of SIN, TRI and SQR. main output waveform is sine. main output waveform is square.
- Page 5 SAVE can save the value of the current frequency, wave and duty, and there are 10 storage position from M0 to M9, which adjusted by code switch, as setting finished, then press “OK” button, when “OK” appeared on the screen, storage is over. If the current value is saved to “M0”, and the changed value will be called in next time, to UDB100xS series, the start frequency of sweep function is defined at M1, the end frequency is defined at M2.
