The Control Panel is self-explaining. The most
important function is frequency tuning.
The frequency is either selectable directly
by keyboard entry or by mouse clicking of the corresponding arrow-buttons (UP/DOWN,
normal & fast tuning speed).
At the rigt side of the frequency display are
the step-width buttons. Smallest step-width is 1Hz, largest is 10KHz.
Additionally there is a button marked with LPT
to select the corresponding parallel interface port (LPT1...3).
The HighIP button below activates the high level
In some extraordinary cases it is possible that
weak DDS-typical artefacts occour. The ALT CLK button can therefore activate an
alternative DDS clock frequency. This would eleminate almost all of those distortions.
