Leo Bodnar Mini precision GPS reference clock teardown

(1/9) > >>

mcinque:
Just a quick look inside the nice and useful reference sold by leobodnar.com.
Just tried, very useful to check cheaply my frequency counter calibration.
Installs quickly, finds the GPS fix very fast and uses an essential and robust software utility to configure it.

See, a MEMS device on PCB layer :)

Hello,

I planned to purchase also the mini precision GPS clock from Leo Bodnard
because it allow programming output frequency in broad range and
 it have  much lower phase noise than lower cost GPS clock from BG7TBL.

Anyway, before to purchase, I asked some info to Leo Bodnard support email,
 but no answer after a week or so. I hope he's fine...

So I post my questions here, maybe some owners would have the answers :
1/ Does it support Galileo GPS lock  ?
2/ Does the provided control software is Linux compatible ?
3/ Is there a manual available with all specs (a real datasheet with measurements) ?
Thank you in advance

Frex

Leo Bodnar:
Hi Frex,
1/ Does it support Galileo GPS lock  ?
Yes, it supports GPS, Glonass, Beidou and Galileo but I tend to keep Galileo turned off.  It degrades high precision timing performance but you need a high quality stable source to see that.

2/ Does the provided control software is Linux compatible ?
You can get Linux version from https://github.com/simontheu/lb-gps-linux

3/ Is there a manual available with all specs (a real datasheet with measurements) ?
All the information is on the website http://www.leobodnar.com/shop/index.php?main_page=product_info&cPath=107&products_id=301 There is not really much to it.

Cheers
Leo

P.S. I can't see your email, please use support@leobodnar.com for contacts

Frex:
Hello,

Thank you for this quick answer.
As I seen, for Linux it's not a GUI but  only by commands line instructions(?).
So now, I just need to make the order ;o)

Note that my two email (01/09  and 02/09) has been sent you
to the right email address. Maybe a spam filter ? can you check ?
(I don't have issue with my email usually)
Regards.

Frex
