|
|
|
| 01-10-2009 | Start working on project |
|
|
|
| 25-10-2009 | Functional specification written. |
|
|
|
| 23-11-2009 | Selection of components, waiting for schematic symbols.
|
|
|
|
|
|
|
| 02-12-2009 | Work on the FmcAdc100M14b4ch\_a is suppressed, because
|
|
|
estimated performance couldn't pass the expectations. |
|
|
|
| 18-12-2009 | Specification and schematic of new version has been
|
|
|
added. |
|
|
|
| 22-01-2010 | FmcAdc100M14b4cha upgrade. Design revised and modified,
|
|
|
better parameters expected. |
|
|
|
| 10-02-2010 | New design made with 3 input ranges and programmable
|
|
|
offset. Need to finalise local clock circuit before PCB layout can
|
|
|
start. |
|
|
|
| 24-02-2010 | Draft PCB layout done. Design document being written.
|
|
|
Design review planned for 2 March. |
|
|
|
| 02-03-2010 | Design review of schematics done.

|
[Review24032010](Review24032010) |
|
|
|
| 25-03-2010 | Small changes involved to the schematic (to make routing
|
|
|
easier), PCB partially updated.
|
|
|
[Review24032010-improvements](Review24032010-improvements) |
|
|
|
| 29-03-2010 | PCB updated. Waiting for Design Office's review. |
|
|
|
| 06-04-2010 | 12 PCBs ordered. 3 will be mounted for prototyping. |
|
|
|
| 12-04-2010 | For availability reasons two resistor values need to be
|
|
|
modified (120<s>121, 510</s>\>511). See issues. |
|
|
|
| 06-05-2010 | 3 cards assembled, SMC connectors ordered but not yet
|
|
|
available. |
|
|
|
| 28-05-2010 | SMC connectors given to workshop. Boards look really
|
|
|
nice. |
|
|
|
| 09-06-2010 | 3 assembled boards received. |
|
|
|
| 12-07-2010 | One board plugged in on Xilinx development kit and
|
|
|
powered. Debugging start. |
|
|
|
| 13-07-2010 | Two channels working\! Limited by Xilinx development kit
|
|
|
clock connections. |
|
|
|
| 30-07-2010 | Current consumption has been measured, document is now
|
|
|
available on the wiki. |
|
|
|
| 30-07-2010 | Changes for the second version of the PCB documented.
|
|
|
Changes mainly to solve thermal problems with regulators. Required
|
|
|
change of DC/DC converter and inductor. |
|
|
|
| 30-07-2010 | ENOB & SNR measured: \>11 bits in all ranges. |
|
|
|
| 03-08-2010 | First harmonic distortion measurements made. Needs
|
|
|
further investigation as with -60dB is higher than expected. |
|
|
|
| 03-09-2010 | The distortion source has been found. For further
|
|
|
information go to [Investigating the distortion

|
|
|
|
|
|
|
| 03-09-2010 | Thermal stability measurements are now available on the
|
|
|
wiki

|
|
|
|
|
|
|
| 03-09-2010 | Frequency response of the anti-aliasing filter will be
|
|
|
verified and possibly corrected. Needs development of software that
|
|
|
shows frequency response. |
|
|
|
| 07-09-2010 | Both I2C buses are working. Accessing memory, setting
|
|
|
sampling frequency and making temperature measurements are now possible.
