6. Operation 
6.1 The First Step Setup For Instrument 
 Ensure that the voltage of main supply is compatible with this instrument. The 
selector on the rear panel states the required AC line voltage. 
 Connect the instrument to main supply with the power cord. 
 Press the Power Switch, all control functions will be shown on the parameter 
display area. 
 
Press                  +                  can recall the default value of this instrument.
 
   
6.2   The Setup of Output Function 
 Press                key to select main output waveform. The Waveform will change 
when  you  press  this  key  each  time.  The  cycle  order  is  according  to  Sine, 
Triangle, Square. 
When the  key  is  pressed,  the  waveform  LEDs  will  light  up  according  to  the 
mentioned cycle order of output waveform. 
 Set different duty cycle ratio (not 50%) for Triangle or Square waveform to get 
±Ramp or different Pulse width square waveform.     
 
6.3   The Setup of Frequency 
  Set  to  Frequency  Entry  mode  by  pressing                button, 
the  FREQ  LED (In 
parameter display area A) will be flashing.
 
 Key in the desired value of frequency. 
 Select a proper unit-button to specify the value. 
 In addition, you can use                                and the Rotate Knob to adjust the 
main frequency value you need. 
 
Note:  The  frequency  range  of  this  instrument  is  from  10mHz  to  15MHz  in  8  Frequency 
Range.  The  details  and  resolution  is  as  below.  But  those  ranges  will  auto  switch 
according to the enter value. 
   
Frequency Range
10mHz~15MHz in 8 Frequency Range (auto switch) 
Frequency 
Resolution 
1.5001MHz ~ 15.0000MHz …(100Hz) 
150.01kHz ~ 1.50000MHz…(10Hz) 
15.001kHz ~ 150.000kHz…(1Hz) 
1.5001kHz ~ 15.0000kHz…(0.1Hz); 
150.01Hz ~ 1.50000kHz…(10mHz) 
15.01Hz ~ 150.00Hz…(10mHz) 
1.51Hz ~ 15.00Hz…(10mHz) 
0.01Hz ~ 1.50Hz…(10mHz) 
 
 Example of the Setup Frequency 
1. To set frequency at 250Hz 
Press                first, then key in                                                and press                .
