1 of 16 USB controled Mux for O'Sope or Meter
### DESCRIPTION
1 of 16 MUX for oscilloscope, with a 10X probe on the PCB.
The Layout can support a TI MUX507, I am unisg the TI MUX506
When it was complete, I put it in to a Hammond 1455N1201RD. I had to cut it down a little.

The Gerbers attached have been corrected such that the 4 Opto isolaors do not need the jumpers shown in the picture. The LM7918 will need pins 1 and 2 swaped, do not run the switcher with out a negitive regulator or a 4.7K load.
USB powered or Isolated power supply. If you don't need isolation use the Jumpers as shown and you can eliminate the Optoisolators too.
The PCB has a +/- switching power supply, there are 3 Vias for TO92 LM78__ and LM79__
I used LM7818 and ML7918 for my board so far I have used it for 0 to 14Vdc.
I have the BNC to a Tektronix TDS1012. I found that I would need to adjust the CAP if I change cables.
### TECHNICAL DETAILS / COMPONENTS
Controled by FTDI FT240XS in BIT Mode.
Using FTDI D2XX_Module.bas
FT_Result = Set_USB_Device_BitMode(255, &H4) ' set All pins as output
### LEARN / TOPIC / BUILD INSTRUCTIONS
Using FTDI D2XX_Module.bas.
Data = Chr(Input)
FT_IO_Status = FT_Write(FT_HANDLE, Data, Len(Data), Write_Result)
For the Varible, Input = 16 is the Enebale D4 then Input 0 will be active.
The incramenting 17 is Enabled, and 1...
On the PCB are LEDs A0, A1, A2, A3 These should help with learning to use the board.
