INTRODUCTION

INTRODUCTION
The function generator outputs different pre-defined waveforms, depending on the settings. Signal wave form,
frequency and level can be changed. The displayed voltage is the voltage measured at the output of the connector.

SWEEP SCREEN

SWEEP SCREEN
A sweep generator generates a frequency which changes with respect to time and is a practical device for recording
frequency characteristics, or to make automated measurements.
Keep the menu button pressed to exit the sweep menu, if the sweep is active then you will see the screen on the
left.You can select the desired waveform and output level

Select the desired waveform
Select the desired frequency
Select the desired frequency step
this setting is used for above frequency change
Select the desired output level
Minimum or start frequency at which the signal starts
Maximum or stop frequency at which the signal stops
Select the desired frequency step
this setting is used for above frequency change
Selection of the loop sweep function of the signal:
Lin. = linear from minimum to maximum, then restart from min to max.
Log= logarithmic from minimum to maximum, then restart from min to max.
Bi-lin = linear from minimum to maximum and back to minimum ...
Bi-log = logarithmic from minimum to maximum and back to minimum ...
Speed at which the signal sweeps from minimum to maximum or
turn the sweep function OFF
