); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] No point using an expensive divider with an 8640B. The close-in noise is dominated by the cavity, especially at the bandwidths used by their lock mechanism, and the broadband floor is ECL at ~-150 dBc/Hz. Just stick a 74xxx74 in there (what *is* considered to be the lowest-noise modern TTL family, anyway?)
