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)
