4 Up and Down buttons

The up or down buttons are used to change or adjust a selected

parameter

WAVEFORM SCREEN

( shown, if sweep is OFF, see further)

Select the desired waveform

(sine, square or triangle)

Select the desired frequency

(1Hz ... 1.000.000Hz)

Select the desired frequency step

(1Hz, 10Hz, 100Hz, 1kHz

or 10kHz)

this setting is used for above frequency change

Select the desired output level

(dBm/Vrms or Vpp)

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.

Minimum or start frequency at which the signal starts

Maximum or stop frequency at which the signal stops

Select the desired frequency step

(1Hz, 10Hz, 100Hz, 1kHz

or 10kHz)

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

SWEEP SCREEN

> access or exit by keeping the menu button pressed

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.
