4.1 Descriptions of controls

4.1.1

Main generator output frequency controls

[1] Range selector
Two cursor keys allow choosing the decade that includes the desired output
frequency being represented on the readout [3].
[2] Frequency control
This is to place the generator frequency on the desired value within the chosen range
by [1] range selector, the selected value mark appears on the [3] frequency indicator.
This control determines the highest sweep frequency, when using the generator on
the SWP function.
[3] Frequency indicator
It displays the value corresponding to the frequency chosen in every decade by
control [1].
4.1.2

Output function controls

[4] Signal selectors
Depending on the selector pressed, the waveform of the signal supplied by the
generator will be square, triangular or sine, respectively.
[5] Variable symmetry selector
On rest position, signal supplied by the main generator is symmetrical and the
variable symmetry control [6] remains inoperative.
If an asymmetrical on-time output signal is desired, that selector should be pressed to
drive on control [6] and to obtain that requested asymmetry.
