• Programming Board,
• Signal Source Board,
• Signal Path Test Board.

First the Programming Fixture, note all the empty space:
Not much is needed in this case.
The connector to accept the connector to the MicroChip ICD (In Circuit Debugger) to program the PIC microcontroller

Next, the Signal Path Text Fixture, with a LOT more parts:

The Input Impedance Measurement Test Fixture was actually an afterthought.
Something easier and more repeatable than holding the DMM probes with one hand.
Simply soldering the test leads to an existing, down level PAM board was the first idea.
But two things were really needed.
First was a strain relief to insure that the solder joints would not be stressed.
Second was some lateral stablity.
To achieve this two additional PAM boards were connected to the bolts,
both upside down to align the bolt holes. Wires secured with cable ties.

This is a classic example of Circuitville's designer's guile

• The fixture was extremely inexpensive,
  • Using boards that would otherwise have been scraped.
  • Only the leads needed to be purchased and
  • One set of leads was used for BOTH inputs
• The fixture was incredibly quick to assemble
  • Less than 4 hours, including labels
  • Minimal soldering
