- What's the divider ratio used ? Perhaps /16 for 3 GHz, /32 for 5 GHz, and /64 for 12.4 GHz, but we really need to be sure. - What's the gain of each one of the four amplifiers present ? - How does the counter aware about the option used ? There is no "intelligence" on the option board, so, the counter may detect the type of prescaler with some pull-up or pull-down resistors somewhere. - What is the exact pinout for the J2 connector ? In order to get an answer, we need to find somebody with a genuine option board willing to spend an hour for the project... ------------------- If you download the 53132A component level information manual from the Agilent site you'll find a schematic of the channel 3 board with values and J2 pinout. The 53131A version of this manual doesn't seem to include this. regards Nigel GM8PZR _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
