LCD Oscilloscope (Front Panel Kit)

This is not a module manufactured by Doepfer but only a front panel kit to mount the Velleman VPS10 LCD scope into the A-100 frame. The kit consists of the plain frontpanel (punched for VPS10, without printing), an A-180 pc board (mounted crosswise below the scope) and all wires necessary to connect the VPS10 to the A-100 bus (power supply) and the A-180 board (signal input).

The connecting lines between the sockets are made with black, waterproof felt pen. A little bit of mechanical skills and soldering is necessary. Three wires have to be soldered to the VPS10 (GND, +12V, signal). One hole has to be drilled into the plastic case of the VPS10 for the passage of the wires, and the VPS10 has to be mounted to the front panel with 4 screws and nuts. A detailed mounting and soldering description is added to the panel kit.

No special measuring cable (BNC - 3.5 mm jack) is necessary as the four right sockets are internally connected to the VPS BNC input (the BNC input is connected to the right four sockets of the A-180 board) . The four left sockets built a second multiple without connection to the VPS10 (same as A-180).

It is also possible to run the VPS10 with an external power supply to save the "high quality" current/voltage of the A-100 bus. The VPS does not require an exactly adjusted and highly stabilized supply voltage. In this case the 300mA can be used for A-100 modules.
