Depends. But, yes they are quite uncommon. If you know your always going to have an external 10 MHz, what you need is a 70310A Option 002. Option 002 deletes the oscillator (and the battery pack). But I've only once seen an option 002. My take is if you had the $'s to buy a MMS setup, you just went ahead and got the full unit. -pete > >> >> >> >> Sent from Samsung tabletDavid Kirkby <[email protected]> wrote:The HP >> 70000 series modular measurement system allows one to configure >> a range of modules to do various things such as spectrum analysis. >> >> There's an oscillator in the unit somewhere (I don't know where), but >> for higher accuracy one can buy an HP 70310A precision frequency >> reference, like this, although this unit is well overpriced.
