2.5. Basic operation
The following description will explain the basic operation to meet the usual need of the users. Every user
whoever has questions should read the corresponding contents in the chapter three of the instruction.
2.5.1 Single frequency function: which is default after booting and outputs single frequency signal.
Frequency setting: Set the frequency value at 3.5 kHz 【Freq】【3】【.】【5】【kHz】.
Frequency adjusting: Press【＜】or【＞】key to move the cursor, switch the adjusting knob left or right to
decrease or increase the digit at the cursor, borrowing from or carry to the former digit continuously. Move
the cursor left for coarse adjusting, and right for fine adjusting. The adjusting knob is applicable for adjusting
digits of other options too, which will not be described any more.
Period setting: set the period as 2.5ms 【Period】【2】【.】【5】【ms】.
Amplitude setting: set the amplitude as 1.5Vpp 【Ampl】【1】【.】【5】【Vpp】.
Attenuation setting: set the attenuation as 0dB（Auto attenuation is default after booting）
【Atten】【0】【dB】 .
Offset setting: set DC offset as -1Vdc 【Offset】【-】【1】【Vdc】.
Common waveform selection: select square (sine is default after booting)【Shift】【Square】.
Duty cycle setting: set the duty cycle of square as 20％【Shift】【【Duty】【2】【0】【％】.
Other waveforms selection: Select exponent waveform (sequence number 16, see sequence number list
of 16 kinds of waveforms) 【Shift】【【Arb】【1】【2】【N】
Below content shows the frequency sweeping function, in order to observe and measure, users may set the
single frequency signal as sine, with amplitude of 1Vpp，and offset of 0Vdc。
2.5.2 Frequency sweeping function:
Press【Sweep】 key to output frequency sweeping signal.
Start frequency setting: Set the start frequency at 5 kHz
Press【Menu】key to light the “Start” letter, press【5】【kHz】.
End frequency setting: Set the end frequency at 2 kHz
Press【Menu】key to light the “Stop” letter, press【2】【kHz】.
Sweeping time setting: Set the sweeping time at 5 s
Press【Menu】key to light the “Time” letter, press【5】【s】.
Sweeping mode setting：Set logarithm sweeping mode
Press【Menu】key, press【1】【N】.
Trigger sweep setting: press【Trig】key, the sweeping will end when reaching to the end point, each time
you press【Trig】key, the generator trigger sweep once. Press 【Sweep】key again to resume to
continuous sweep.
2.5.3. Burst function:
set continuous frequency as 1kHz.
【Burst】key, output burst signal.
Repeated period setting: set repeated period as 5ms
【Menu】key, light “Period” character, press【5】【ms】.
Pulse count setting: set pulse count as 1
【Menu】key, light “Ncyc” character, press【1】【N】.
