Hi, Both slashes work fine for me! That is an artifact of IE on Windows. According to RFC 1738, URLs use the '/' to separate components of a hierarchy. Because MS-DOS (and therefor Windows...) uses '\' as a path separator, people using Windows will type the wrong separator in an URL. That is

Hi How much warmup time do you have before you go mobile? If the mobile unit can be kept hot before it heads out - the DOCXO wins. If it's a power up and roll in 10 minutes sort of thing, then the Rb is the only way to go. Bob On Nov 19, 2010, at 3:56 PM, Dave Jabson wrote: Greetings,

Hi Dave, forgot to mention: The PRS-10 also has a limited temperature range only up to +65C, so military applications are a no-go. A good DOCXO will have +75C or even +85C capability. Also, the spec for the PRS-10 is 1.18E-012 per Degree C temperature change, and the units I mentioned

Hi If high temperature is an issue, keeping the Rb cool will be a major chore. The OCXO will be far more happy at 75 than the Rb will be at 65. Depending on just how mobile we're talking about, the OCXO may have some issues with 2G tip / acceleration. There's a lot to consider in a setup
