Cybersecurity — software & network: not checked

This report predates the cybersecurity (software & network) check, or the lab's snapshot doesn't record software dependencies yet.

Readiness: DPScope USB Oscilloscope

Verdict: Ready with caveats · 2026-07-19 · est. parts cost $65–$75

This lab is implementable but requires attention to component package transitions and obsolescence. This is a baseline check to establish a sourcing and pricing foundation. The core microcontroller is available but requires a specific suffix (-SP) to meet the 300 mil DIP footprint requirement, and the original trimmer capacitors and DIP sockets are now obsolete. The project website has migrated, making local hosting of critical firmware binaries a high priority.

Action required

Part Problem Recommended action
dsPIC30F2020-E/P Snapshot part number mismatch Order dsPIC30F2020-30I/SP to ensure the required 300 mil footprint.
TZ03Z500E169B00 Obsolete Order substitute GKG60015 (active stock).
4828-3000-CP Obsolete Order ED281DT or equivalent through-hole sockets.
dsPIC Firmware External dependency risk Download and host the .hex and MPROG files locally; the primary domain has shifted.

Substitutes

For part Substitute Differences Verified Judgment
MCP6S22-I/P MCP6S92-E/P Higher bandwidth (10 MHz); better availability. package + pinout Acceptable
TZ03Z500E169B00 GKG60015 12–60 pF (vs 10–60 pF); higher voltage (100 V). package + range Acceptable
4828-3000-CP ED281DT Standard 300 mil DIP socket. 28-pin, 300 mil width Acceptable

Instructors should verify substitute footprints against the PCB layout before procurement.

Other dependencies

  • Microcontroller Firmware: Critical; available at dpscope.freevar.com. Must be flashed to dsPIC before assembly.
  • PC Application: Legacy Windows software; Windows 11 compatibility requires testing with "Compatibility Mode."
  • FTDI Drivers: Standard VCP drivers required from ftdichip.com.
  • Configuration File: MPROG file required to set the specific serial number for hardware recognition.
  • Fabrication: 2-layer PCB (approx 4.25" x 2.25"); status not checked.

Watch list

  • dsPIC30F2020 Stock: DigiKey stock is extremely low (7 units); procurement should be directed to Mouser.
  • Resonator Status: The CSTLS16M0X53-B0 is "Not For New Designs." While current stock is high, future cycles may require a transition to SMD resonators with board modifications.
  • Software Hosting: Original dpscope.com has moved to a free hosting domain; mirror all binaries locally to prevent loss of access.
