Ben Jackson / Vector Network Analyser Project - History

v0.1 completed, producing gerbers

gerbers to be sent to jlc pcb pending their acceptance, they will be produced

initial pcb design

initial layout and grouping of components complete

beginning pcb layout

pcb layout process begun

custom footprint for couplers, added decoupling caps

added custom footprint for directional couplers - will need to verify it

added decoupling caps to ad9851

finished controller, chose compatible switches

controller and rf switches have been completed.

ToDo: finish filter design for RF Source, add auto gain control
ToDo: finish directional coupler footprints
ToDo: PCB Layout

micro-controller pins labelled

micro controller pins have been labelled, the pins on the bottom are yet to be linked to them.

still to wire up ftdi chip,

still to decide upon rf switch control schema.

changed inductors to a single transformer component

inductors in the directional couplers was changed to a single transformer

this will help with later layout opperations

adjusted main schematic to suit initial presentation

i moved a few blocks around so that the cropped version of the block diagram would fit nicely in my semester 1 presentation

block diagram for presentation completed

at this stage i have completed the overall block diagram for the initial presentation.

the blocks are mostly empty and require further development. the overall block diagram neglects power supply connections for clarity, these will be added internal to the blocks.
