Agilent E7495 linux root account
RCHRDM:
I am in the process of hopefully getting some additional parts to replace those missing from y E7495.
Could you please step me through the "hacking" process to enable the power meter? I can follow along with the my instrument now.
BTW, I have a service manual now if anyone needs one.

What do you mean about missing parts?
The power meter is not a software option. If it's physically installed, it will be working (I think).
You have the real service manual? I'd love to see it. PM me.

After I got the E7495 home, I noticed that it was missing the connector for the power meter. (Someone had put tape over the hole, so I could not tell from the auction photos.)
I took it apart to repair a problem with the LCD cover and found that the power meter board was installed, but two ribbon cable connections were missing. I assume one of them is for the power meter connector on the case.
I also found that there were a few other missing things including the main case gasket, a couple of screws, and the cover for the PCMIA area.
There is a guy who has a parts machine, so we are talking about pulling some parts from it.
When the instrument is powered up, the power meter button is grayed out, so I assume the option is not activated.

To extend the lower range, can we build a transverter with a 400MHz LO to cover 0Hz to 400MHz for the VNA measurement? and would a transverter work for SWR measurement.
It would be great if a SW hack could be found.

The company I work for have a N1996A and I wanted to enable the stimulus/response N8995A-SR3 option so I contacted Keysight and they said the unit is no longer supported and that I can't even pay to get the option enabled. I mentioned that people have hacked the software to enable options, and they just referred me to their forums and said hopefully I can find someone who can help. So now I have a clear conscience with hacking the firmware to enable options since I tried the formal path. Can anyone explain how I can do this, considering I don't have much experience with Linux? I read over this forum but couldn't get a clear picture of what exactly I need to do. I understand I need to patch the firmware, PA0PBZ mentioned a patch for the E7495 but that uses the elgato process, I don't know what I need to do for the N1996A. Can anyone please help?
