I'm considering doing that actually. I've seen some Agilent/HP GPSDO units appear on auctions on and off here as well. Not sure if they're any good these days though.
Got itchy spendy fingers at the moment. Managed to shift some radio gear already. Looking at LCR meters. Any suggestions welcome. I'm sure I'm asking in the right place
Looked at Peak LCR45 which is about right but the damn thing doesn't do ESR. You have to buy another box to do ESR.
have no personal experience with the hp Zbox. but know of others who have them and are happy with them.
used to have and ancient gps frequency receiver (telecom solutions?) that was pretty good, but about every 30-40 minutes the 10 Mhz output would drift .025-.05 uSec (in about a minute) compared to my rubidium or my loranC frequency receiver. it would then slowly drift back over about 10 minutes. so its long term average was fine. guess you could call that behavior jitter? always assumed that it was somehow related to a handoff between satellites as they appeared/disappeared over the horizon.
the newer Nortel box does not have noticeable drift/jitter. you get bored watching for it and give up after a couple of hours. watching satellites come and go via lady heather can become addictive however. sort of wish they had chosen a different icon for that software. swmbo still does not believe its not my link to some kinky adult site.

AND Obama killed the loranC transmitters with an executive order back in 2010, so I lost interest in attempting automated long term comparison, statistical analysis, and measurements. that path leads to serious time nuttery……..and I am on the wagon.
Changing the icon for an executable is actually pretty easy; though like with everything Winblows, what once was right out in the open is now obfuscated to death.
Find yourself a graphic you like ( or one you hate, if you like
) of approximately the right size in .jpg, .tif, or .png format. Google "Icon converter" and you'll find oodles of websites that will happily convert it to .ico format, and even resize. Not sure anymore, but I think max used to be 64 x 64 pixels. You may find you need to edit to simplify the image in PAINT or some photo editor to get something that doesn't look like utter drecht once converted; this is the only real PITA part.
Save your newly-minted .ico file in a safe place like a dedicated folder on the root of your HDD or in DOWNLOADS.
Find the executable, open it's properties, then click on the "ICON" dialog. From there, browse to your ICONS folder and select your icon. If the executable's name changes names, you'll have to do this again; or sometimes if it updates itself.
Cheers!
