your output is a square wave on 50 Ohm as write close the connector. Use
this filter to have a clean sinewave output.

Hi Mike,
You have not mentioned the best Rubidium available, the HP5065A. Last week two
of them are sold on ebay.
Second chose can be the Efratom FRK or M100, than all the others.

Hi all,
Among the many experts and documentation available on the internet my question
might seem trivial .
I'm looking for a written document , not generic information, describing the
procedure , timing and methods of calibration of one or more standard present
in a laboratory frequency
Tom,
it is not, see the Farnell code below followed by Amphenol part number:
Farnell code: 1914117 pn 97-3106A18-22S connector
Farnell code: 1654733 pn 9779-513-8 plastic ring
Farnell code: 151628 pn 97-3057-1010-1 cable clamp and bush

Ulrich,
you can buy it from Farnell:

I have an Agilent 34970A data logger. It use the "Bencklink Data Logger3" as
software.
I would like to capture the graph in a printable format instead the original
.csv . A .gif will be good to be inserted in documents.
Can some one help me?
thanks ,

Ok Thank you all you, I will try these solutions and I will ask also to
Keysight.

Hi Corby,
very interesting. I have some questions?
1) it is difficult to read the frequency value on the plot. Can you specify?
2) how do you set the offset of the op-amp trimmer ?
3) do you think is possible to use the -20V on the HP5065A instead the -12V
from the DC-DC converter?
4) what
Hi,
I agree with you. Some HP spectrum analyzer have internal 50 and 100 Hz spurs
down to -80dBc due the fan as described in the manual. It can be the spurs are
from the test set and/or connection cables. If your oscillator is battery
powered you can be sure the spurs are not from the source.

Hi Scott,
I have never find a photodiode faulty. When applied 20 volts to the lamp it
should come on within about 10 seconds, and the PHOTO I meter on the panel will
be between 20 and 50. If this does not happen the most probable failure is the
resistance R1 on the lamp board (1330ohm
Hi Scott,
the emitter resistor have to be in the range 9 to 15 Ohm. Probably the high
temperature and current have burned it out.
Replace it with a 12 Ohm 1/2 W resistor, It will work.

I am working on a project to compensate pressure and temperature starting
from the Corby Dawson study.
I am planning to made an smd version of the board.
This circuit with some minor change can be applied to any Rubidium standard.
