You can discipline a HP 5065A easily using a Shera with the Tbolt 1 PPS
and a LTC 1655 DAC in stead of an AD 1861.

Edgardo,

Congrats on getting the 5065A up and operational. Make sure the A11 Board
(Temperature Controller) is all OK. Failure there can destroy the A12 RVFR
Assembly. There is a lot of 'expertise' on the list for this unit.

What is the serial number of your unit and what is the part number of the
manual you have?

I have a couple of manuals and I may also have the 'change sheets' that
updates the manual to your serial number. It may take me a while to chase
that down but if I have the 'change sheets', I can scan them and send them
to you.

I have not heard of anyone 'disciplining' the 5065A by GPS, other than by
hand from week to week. However, the 105B has a built in connection on the
back that is great for that purpose (negative slope, as I recall) and I
have
done that using a Brooks Shera controller board and the 1 PPS from my
TBolt.
It works quite well.

Subject: [time-nuts] HP-5065a bought and finally working!

Dear Group,

I wish you well.

Do you recall a message and thread about a month ago with my concerns about
buying a used / unknown condition HP-5065a rubidium frequency standard? I
bit the bullet and bought it. Almost mint condition (cosmetically speaking)
and with several operational issues.

Well, It took me several weeks to put it back to work. Several capacitors
on
several boards along with a couple of transistors and an IC were replaced.
After that any being bored by the yellow light, it finally came off to
allow
a beautiful green lock condition light. I went through the necessary steps
to tune it and calibrate it. Now, as I have been told recently. "You have
been bitten by the Time Nuts bug." I am not complaining at all.

Now the technical issues if you kindly allow:

a. Does anybody have an HP-5065a manual for the latest versions? Mine
(which
I downloaded from the Internet) is intended for earlier versions. It seems
I
have one of the last produced units. I would kindly appreciate any help on
this and I am willing to pay for time and expenses to anybody who could
help. During the repair process I found several differences in the earlier
versions design and had to figure out hoy mine works.

b. Is it possible to build a GPSDRb? I would like to know if it is
reasonable to pursue the goal to discipline the 5065a with a TB which I
also
got recently.

c. I am waiting for the delivery of a recent purchase. An HP-59309a Digital
Clock to go with the HP 5065a. How I wish I could find the optional LED
integrated optional clock and 1PPS output. Is my purchase a good match for
the 5065a? Any other suggestions to drive a clock?

d. I am waiting also for de delivery of an HP-105b mint condition quartz
frequency standard. Would a second 59309a make sense to use it with this
quartz standard? Or just saving it for a Cesium? Anybody willing to sell a
spare, dust gathering, clean unit to me?

e. Any suggestions for software of lab equipment to measure my experiments
like AD, jitter, phase comparisons, etc?

While I wait I am doing some experiments with a FE Rb standard to
discipline
an Adret synthesiser to output 32.768 KHz to directly drive a Nixie clock
kit I just finished building.

Your comments are surely welcome. Thank you!

Kind regards,

Edgardo congratulations. The 5065 is a really nice unit. I have one also
but earlier and luckily my manuals are on the internet.
It could be disciplined but the fact is for me at least I do not want to.
Leave a great device as is. There are lots of cheap RBs around and even
nice oscillators that can be disciplined.
Hack those and leave 5065 clean and complete it will serve you very well.
Good luck.
Regards
Paul.

Dear Paul,

Thank you for sharing your comments with me. I am back from a business trip and found lots of answers to my concerns. The instrument continues in the "green" with voltage indication within limits. You are right. After valuing the 5065a, I rather play with the cheap Rbs.

Take care and enjoy the weekend.

Dear Bert,

Thank you for your always expert advise. I am receiving an HP 105B next week and for sure I will be doing some disciplining with the Thunderbolt. I just started to gather operational information on the 5065a to start a record. I also have been reading about those methods and also going deeper with your information.

Cheers!

Edgardo,

Congrats on getting the 5065A up and operational. Make sure the A11 Board
(Temperature Controller) is all OK. Failure there can destroy the A12 RVFR
Assembly. There is a lot of 'expertise' on the list for this unit.

What is the serial number of your unit and what is the part number of the
manual you have?

I have a couple of manuals and I may also have the 'change sheets' that
updates the manual to your serial number. It may take me a while to chase
that down but if I have the 'change sheets', I can scan them and send them
to you.

I have not heard of anyone 'disciplining' the 5065A by GPS, other than by
hand from week to week. However, the 105B has a built in connection on the
back that is great for that purpose (negative slope, as I recall) and I
have
done that using a Brooks Shera controller board and the 1 PPS from my
TBolt.
It works quite well.

Joe

Subject: [time-nuts] HP-5065a bought and finally working!

Dear Group,

I wish you well.

Do you recall a message and thread about a month ago with my concerns about
buying a used / unknown condition HP-5065a rubidium frequency standard? I
bit the bullet and bought it. Almost mint condition (cosmetically speaking)
and with several operational issues.

Well, It took me several weeks to put it back to work. Several capacitors
on
several boards along with a couple of transistors and an IC were replaced.
After that any being bored by the yellow light, it finally came off to
allow
a beautiful green lock condition light. I went through the necessary steps
to tune it and calibrate it. Now, as I have been told recently. "You have
been bitten by the Time Nuts bug." I am not complaining at all.

Now the technical issues if you kindly allow:

a. Does anybody have an HP-5065a manual for the latest versions? Mine
(which
I downloaded from the Internet) is intended for earlier versions. It seems
I
have one of the last produced units. I would kindly appreciate any help on
this and I am willing to pay for time and expenses to anybody who could
help. During the repair process I found several differences in the earlier
versions design and had to figure out hoy mine works.

b. Is it possible to build a GPSDRb? I would like to know if it is
reasonable to pursue the goal to discipline the 5065a with a TB which I
also
got recently.

c. I am waiting for the delivery of a recent purchase. An HP-59309a Digital
Clock to go with the HP 5065a. How I wish I could find the optional LED
integrated optional clock and 1PPS output. Is my purchase a good match for
the 5065a? Any other suggestions to drive a clock?

d. I am waiting also for de delivery of an HP-105b mint condition quartz
frequency standard. Would a second 59309a make sense to use it with this
quartz standard? Or just saving it for a Cesium? Anybody willing to sell a
spare, dust gathering, clean unit to me?

e. Any suggestions for software of lab equipment to measure my experiments
like AD, jitter, phase comparisons, etc?

While I wait I am doing some experiments with a FE Rb standard to
discipline
an Adret synthesiser to output 32.768 KHz to directly drive a Nixie clock
kit I just finished building.

Your comments are surely welcome. Thank you!

Kind regards,
