Signal Generator from Stuff I've Already Made/Bought
- NANO-BKOUT
- 2x NewPot2
- PulseGen
- UNI-OPAMP-08 or ANA-SIG-CON
- AD9850 card on GRID49 card
- 0.96" I2C OLED card
NANO-BKOUT
- Arduino NANO Breakout board
- 5V Power Regulator
- Probably don't need all the connectors
- Why not just install them?
- Good for 5V power/ground distribution
- Install I2C connector
- USB connector
NewPot2
- Use 2x boards for menu control
- Used as 0.1" pitch connector to Encoders
- Install R1-R3 = 10K
- Don't install ATTiny85
- Don't install C1
- Don't install D/A converter
NewPot2 H1 Connector
- Rotary Switch B
- VCC
- Unused
- Rotary Switch A
- Rotary Switch pushbutton
- GND
PulseGen
- Two boards
- Use 1 to drive square wave on BNC to 50 Ohm load
- Install BNC, 74AC14, 249 Ohm Series resistors
- Don't install oscillator parts
- Use other to connect to BNC for Sine Wave output
- Only install BNC
- Use 1 to drive square wave on BNC to 50 Ohm load
UNI-OPAMP-08
- Drive Sine Wave output
- Route to PulseGen card for BNC use
- Use 100 MHz GBWP Op Amp
- Disable all other channels
AD9850 Card on GRID 49 Card
Mechanicals
- Mount to Front Panel
- 49mm stack
- NANO-BKOUT
- UNI-OPAMP-08 or ANA-SIG-CON
- AD9850 card on GRID49 card
- Front or Rear Panel
- 2x PulseGen - could be stacked or bolted individually
