Signal Generator from Stuff I've Already Made/Bought

NANO-BKOUT

NANO-BKOUT-P1010078-800px.jpg

  • 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

NewPot2-6111-640px.jpg

  • 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

  1. Rotary Switch B
  2. VCC
  3. Unused
  4. Rotary Switch A
  5. Rotary Switch pushbutton
  6. GND

PulseGen

PulseGen 5242-720px.JPG

  • 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

UNI-OPAMP-08

  • Drive Sine Wave output
    • Route to PulseGen card for BNC use
  • Use 100 MHz GBWP Op Amp
    • Disable all other channels
