I have asked Agilent
if stock versions of the 53230A and 53132A switched the internal oscillator out
of circuit with an Ext Ref signal
applied. I thought
Agilent's engineer was intentionally vague but said the oscillators were
indeed switched out of circuit on the counter with Ext Ref signal
I've seen a pin-out for the outer-oven 6-position connector (2 heater wires,
2 thermistor wires), but I've not found anything on the pin-out of the other
6-position connector. Has anyone come across the pin-outs for the
10811-60165 connectors?

TomK,
If anyone has technical contacts deep within Agilent, let's see if this issue
can be resolved. I would have bought a 53230A when it came out a few years ago
but my eval units showed this clock noise problem. That plus the poor quality
of the ref out made me think the designers were
Chris,
The 10811-60165 may be similar to the HP 10811-60158
that uses using the following pin-out:
1 - BRN Oscillator Return (Com)
2 - RED Oscillator Power (+12V)
3 - ORG Oven Monitor Return (Com)
4 - YEL Oven Monitor Output
5 - GRN Oven Power (+18-24V)
6 - BLU Oven Return (Com)
The following
Hi,
I have a couple that look like the one in these pictures minus the the
little frequency control board.

One of mine would not lock so what I did I looked at my other 5680A
which is the type referred to in the tip about C217
That pin-out sounds promising as this unit has
BLK-RED-BLK-ORG-YEL-GRN-BLU, which seems consistent with the one that
you provided. Did you source that from one of HP's various guides or
somewhere else?

Hi
Well at least this got me digging a little.
If you grab a copy of the 53230A spec sheet and look under the external
reference input, it’s pretty well described. It will accept 1, 5,10 MHz as an
external reference. It will lock over a 1 ppm range with the XO option and 0.1
ppm with the
Thanks Tom and Bob, I have been thinking of contacting Agilent for some time. I
think they are a great company with some good products, but there are a few
real blind spots in some current products. I also have seen in the past a
genuine interest in listening. I would be willing to approach
Chris,
I bought a number of 10811-60158 so I determined the pin-out
from an actual unit.
