[time-nuts] Jupiter GPS 10 KHz pin

I have a Jupiter based receiver that is not one of the standard modules. I'd like to see if I can get a 10KHz output from it, but I don't know which pin of the 144 possible options to look at. Would someone with a Jupiter board trace the connection from the 10 KHz output back to the pin on

[time-nuts] HP 5334B C-channel--was Re: Which HP Frequency Counter?

I was the project manager and chief EE on the HP5334B project. The 5334A had a C channel using an HP made divide by 10 prescaler that had a factory cost of ~$100. In the 5334B, I replaced this with the Fujitsu MB506 divide by 8 prescaler, which cost something like $2. The firmware was changed

David, On the site http://gpskit.nl/, in the downloads directory, you can find a lot of info on the Rockwell Jupiter board. I know the info you are looking for is in there somewhere. Best regards, Tom On Thursday 20 March 2008 14:33, David Carr wrote: I have a Jupiter based receiver that is

Re: [time-nuts] Jupiter GPS 10 KHz pin

Tom, Thanks for your reply. I looked through the documents on that page but unfortunately I don't think any quite address my question. I think they'd have to have a schematic of the board itself to do that. If someone would just stick a multimeter probe on the 10 KHz connection of their module

Re: [time-nuts] Jupiter GPS 10 KHz pin

David, If I hold my Jupiter in the position where the connector is on the left and the 11577-11 is facing me then the 10kHz is on pin 20 of the connector (top right) and this pin is connected to pin 13 counting from the top right-hand-side of the IC. In some ugly ascii graphics:

Re: [time-nuts] Jupiter GPS 10 KHz pin

David, I can confirm. I measured it on a TU30-D140 and its on the same pin. Bruce's graphic is rotated 180' compared to my ascii graphic. Tom David On the TU30-D165 version of the Jupiter the relevant pin appears to be the 13th pin up from the bottom on the LHS of the large chip in the

[time-nuts] NI GPIB cards

This group seems to be very GPIB savvy, so I have a question (vaguely related to time and frequency) - is there a real difference between the half sized current one large chip NI PCI-GPIB card and the older and larger version with multiple chips that proceeded it ? Which would you

Re: [time-nuts] NI GPIB cards

It is always hard to tell with NI because they are so mumm about their designs. If the new card works with old drivers (most will), it is probably a repackaged version of the old card with more of the stuff in a gate array or xPLD instead of discretes. If it requires (or recommends) a new driver,

Re: [time-nuts] Jupiter GPS 10 KHz pin

Tom and Bruce, Thanks for probing out this line for me. You two are indeed correct, as I found a nice looking 10 kHz signal on the pin you identified. My GPS is a TravRoute CoPilot serial hockey puck which happens to have a Jupiter chipset (FW 1.83 1997). I thought that this GPS (my first) was
