I've tried all the parameters and the update rate still drops to about once every 3 seconds when I turn print on! You still see the 1pps strobing the input channels every transition even with print on. I was using just pins 2, 3 and 5 on the rs232 and switched to a "full" cable with no improvement. Since the problem occurs even without the laptop connected I don't think it's a cable issue. Do I need to have the laptop issue a GET command or something after each transmission? Heeelp! Cheers, Corby

I have a HP53131A and don't have this issue, the only thing I can think of is that you have the cables swapped i.e. the start edge on ch2 and stop edge on ch1. I have firmware REV:3703, If there are any settings you want me to try I am happy to help.

Hi There may be some deep dark setting in there that would require a pacing process. If it’s there, I’ve never ever run into it. I’ve been pulling data out of 53131’s and 53132’s for as long as they have been around. Not all of it has been by serial, but some of it has. I’ve likely used every version of firmware they ever put out. I believe there is a “hard reset” that puts all the fiddly eeprom stuff back to defaults. I have no idea if it clears calibration (I *assume* it does not). The only time I ever tried it was back in the 1980’s so I don’t have the procedure right here …. It did no good at the time. The problem with those counters was a piece of my code that demonstrated how quickly you can wear out an eeprom …. ooppsss … Bob > On Dec 3, 2016, at 12:47 PM, cdelect@juno.com wrote: > > I've tried all the parameters and the update rate still drops to about > once every 3 seconds when I turn print on! > You still see the 1pps strobing the input channels every transition even > with print on. > I was using just pins 2, 3 and 5 on the rs232 and switched to a "full" > cable with no improvement. > Since the problem occurs even without the laptop connected I don't think > it's a cable issue. > Do I need to have the laptop issue a GET command or something after each > transmission? > Heeelp! > > Cheers, > > Corby > > _______________________________________________ > 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.
