+10V. In this situation, the instrument becomes a DC power source, which can output preset DC voltage signal.
3.2.9 Select the Waveform of Channel A
The channel A can output three kinds of waveforms: sine wave, square wave, and pulse wave. Press function key
[A- ], [A- ] to select the corresponding waveform. When the square wave is selected, the duty cycle is
default to 50%.
3.2.10 Set the Duty Cycle of Channel A
Press function key [A- ], select “Duty” by the corresponding soft key. The current duty cycle value changes to
yellow. A new duty cycle data can be input here by numeric keypad or rotary dial. The duty cycle value can be set
at any value between 0.1%~99.9%. When the converted duty cycle value is less than 0.1%, the duty cycle value is
displayed as 0.1%. When the converted duty cycle value is greater than 99.9%, the duty cycle value is displayed
as 99.9%.
3.2.11 Set the Phase of Channel A
Select “Phase” by the corresponding soft key. The phase value changes to yellow. Input a new phase data here by
numeric keypad or rotary dial. The phase can be adjusted at any value between 0~360 degree. The phase
resolution is 11.25 degree.
3.2.12 Set the Output Impedance of Channel A
Select “Impedance” by the corresponding soft key. The impedance value changes to yellow. The function
generator is default as high impedance. The impedance value can be set by numeric keypad or rotary dial and the
output impedance is 50Ω.
3.3 Setup of Channel B
Press key [Channel] and select “CHB Alone” function.
3.3.1 Set the frequency of Channel B
Select “Frequency” by the corresponding soft key. The current frequency value changes to yellow. Input a new
frequency data here by numeric keypad or rotary dial. There will be corresponding frequency output in CHB
output terminal. Same as channel A frequency, channel B frequency can also be set and displayed in the way of
period.
3.3.2 Set the Amplitude of Channel B
Select “Vpp” by the corresponding soft key. The current amplitude value changes to yellow. Input a new
amplitude data here by numeric keypad or rotary dial. Press the soft key corresponding to the amplitude units to
confirm the new data input. The function generator outputs the desired signal at CHB Output. The amplitude unit
of Channel B can only use Vpp but not Vrms. The channel B does not have the amplitude attenuation or DC offset
functions.
