DRB 30
Control Software
++
Control Panel
The application software displays a small window that you can position anywhere on your desktop and can be run together with the SDR software.
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).
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.
