Bill of Materials (BOM)
This page lists the equipment and consumables required for the Extracellular Electrophysiology Electronics Practical.
Packing List
Students should pack the following parts in a box:
- Multimeter (with 2 probes)
- 1 box of jumper wire
- 1 resistor kit
- 2 capacitor kit
- 1 bag of LED
- A breadboard with 2 amps on it (everything else removed)
- 1 pair of needle for recording
- 1 picoscope with USB cable
- 2 or 3 oscilloscope probe
- 1 bnc to crocodile clamp cable
- 1 bnc cable
- 1 crappy oscilloscope with power cable
Equipment
These items are part of the lab bench setup and should be handled with care.
| Item | Description |
|---|---|
| Benchtop Oscilloscope | 2-channel oscilloscope with integrated display and signal generator. |
| PicoScope 2204A | USB-based digital oscilloscope for computer-based measurements and frequency sweeps. |
| Multimeter | Digital multimeter for measuring resistance, capacitance, and DC voltages. |
