Amos, what you are dealing with is an attenuator specifically made for that one instrument. They are in short supply and are crucial for the analyzer to work properly and to display the actual input level on both the screen and readout LED.

Anything but the proper part will degrade the instrument, and possibly create a "Frankenstein's monster", with outboard "fixes". I hope you realize that you are involved in a possibly very expensive and time consuming project; and may have to settle for "good enough" rather than a 100% reliable, accurate instrument.

Will, Yeah. I have thought about this option too. But that means I have to give up the ability to internally choose attenuation. Right now, I am facing the issue of choosing the cable that go between the RF connector and the coax switch (K2). No experience on choosing or specifying one before.....

Amos - you can use an external atten. to keep the input signal below +20 dbm. Will In a message dated 8/31/2011 1:06:30 A.M.

Now, I found it difficult to find a cheap source for 08565-60084 attenuator. Does any one know the replacement part for 08565-60084 (A34, RF attenuator) in HP 8565A? It does not seem to be easy to obtain this attenuator ($400). I wonder if anyone knows any information about this attenuator. If obtaining one is difficult, what options do I have? Also, I wonder if this attenuator is really needed to make the system work. Thanks in advance. Amos [Non-text portions of this message have been removed] |
