Using the Julia REPL#

When I started using Python, I didn’t use the Python REPL much. I took a more conventional approach to running Python as a scripting utility using executable files. When I started using Julia, I found the REPL much more valuable than Python’s. It might be the same, however, I’ve found myself using Julia via the REPL far more than as a scripting language. A couple of pointers:

Analyzing Circuits Using the Espotek Labrador: DC Sweep

Using the Labrador and a DMM, perform a DC sweep of an inverting amplifier. From our previous lab post we saw the simulation values for a DC Sweep. In this lab, we’ll use the Labrador along with a DMM to determine if our measured values match those of the simulation.

Build the Circuit on a Breadboard#

  1. Using this circuit, implement on a breadboard so it is similar to the image below.

  2. Parts List:
    • LM358 Operational Amplifier
    • Frequency Generator (Espotek Labrador or ADALM1000)
    • 9V power supply
    • 2k ohm resistor (or 10k potentiometer)
    • 5k ohm resistor (or 10k potentiometer)

Notes:#

  1. Vo is pin 1 on the chip
  2. Vn is pin 2 on the chip
  3. Vp is pin 3 on the chip
  4. Make sure you attach 9V to pin 8 and Ground to pin 4

Using a Potentiometer as a variable voltage source#

Notice the potentiometer on the right on the breadboard. There are three terminals:
