Regarding sensitivity of E74 on low freq...

Last night have tuned down on AM 0,5-1,6 MHz band, result lot of AM carriers - not good....

Therefore just made small test by joining E7495B with FT-817 (Yaesu), same LW antenna with N 1 to 2 switch.
Conclusion is what 817 hear that E74 can "see". Must try also on 3,79-3,80 MHz DX window
during the night or early in the morning (gray zone) too but for day time here is 14.070 MHz PSK stream.

The E7495 does have a higher noise floor bellow 375Mhz(~37dBm more). This is due to internal Pre-AMP limits.

I have an E7495A and an E7495B.  Does anyone know:

1) What the latest firmware version is for each and where to download it?
2) Where replacement batteries can be purchased at a reasonable price?

Thanks!

The batteries are made by Inspired Energy, the original model number is NI2040AG (if it carries the Agilent label) or NI2040MG (if it carries the IE label). There are now variants with larger capacity:

http://inspired-energy.com/standard_products/NI2040/NI2040.htm

In the UK, they're sold by Accutronics:

Hello Everyone,
I have an e7495a from ebay and i'm very happy with it.
My Questions are:
1. Is it possible to use SCPI over Lan?
2. There is also a Webserver, it asks for a Password but the root-or guest-password doesn't work.
3. Anyone an Idea, how to add other Modulations to the Generator?

Thx to Alll for the nice Work on this Device till now  :-+

I bought one of these a few weeks ago, and through my searching around I have found the service manual for it, as well as the latest FW. The FW is the same for both the E7495A and E7495B models.

Service Manual: https://www.dropbox.com/s/39mbjsaf5m5pkmr/e7495serv.pdf?dl=0

Latest FW (A.06.25): https://www.dropbox.com/s/ze8lq9b2e0j8r7j/full625.zip?dl=0

The service manual details the installation of the FW as an upgrade (just unzip to a CF or PCMCIA card) and insert before boot. Then confirm the upgrade using the OK button.

You can also do a fresh install by instead of pressing OK at the upgrade screen, press the bottom button on the right hand side of the screen, the one directly opposite the screen from the NO option on the analyzer.

Thank you very much
 :-+  :-+  :-+
Feels a little bit faster with the new Firmware  ;)
My next Step will be a self-made Battery, because an original one is way too expensive.

I was just going to make a battery that attaches to the back of the instrument and connects using the existing DC barrel connector.

It would be interesting to make some batteries that use the SMBus protocol that are not the rare ones that it comes with. You could probably do it with some lithium primary cells and 3D printed endcaps along with a little controller board.

It would probably be cheaper than the $200 that the replacement batteries are going for, even for one-offs.

Hello everybody

In find very interesting this approach of Agilent E7495 ,specially getting access into ARM LINUX system as root.
My problem is on CSA n1996a ,it works very well as guest-TELNET using "noname " password , but unfortunately
telnet as root can not login using the E7495 "wh1skers" password.
Could someone help me?
Thank you. :)

There's probably nothing behind there, at least on the N1996A there's nothing.

Thanks for the response.

The reason is I can't save (download) the collected data.

I don't have PCMCIA and CF card and readers (or adopters).

According to the Guid :
 -Two RS 232 (DB-9) (reserved for future use)
 -Two USB 1.1 (reserved for future use)
 -One LAN Port 10 Base T
 -PCMCIA Card slot
 -CompactFlash memory (type 1 & 2)

Is USB working after version upgrade?

Thanks to    PA0PBZ

My  CSA n1996a, FW :A.02.07 works full options ! The USB mount and transfer method very simple.
As hex editor I have an Octeta on a Linux MINT OS.

Best regards !

Thanks to everyone that has contributed to this interesting thread..  It looks to be a pretty cool instrument that has some hacking potential.

I just picked up a E7495B from fleabay and have been playing a bit. The original firmware as received was v6.10 which I upgraded with the 6.25 fw from the link in this thread. I was able to telnet into the device and back up the /flash directory to CF first. One thing I am noticing I did not appreciate before the update is a periodic hesitation in the SA display; once about every 10-12 seconds there is a about a 1 second pause in the display response. It is fairly subtle but definitely there. Has anyone else noticed it?

My unit has the 510 complex signal generator. It seems to be a pretty common option.  It sure would be great to get some conventional FM modulation from the SG to provide partial "service monitor"  functionality for testing analog FM radios and repeaters . It can generate QPSK signals for IS95 forward and reverse links so one would guess the hardware may be capable of conventional FM or at least PM modulation with it's internal ARB. Any thoughts?

Even better would be the ability to add more digital modulation modes like P25 and DMR.  That would make it really useful.

Dave, K7DMK

Hi wavebits

I did find the data files for the complex signal generator on the device, i think you can find them in

Code: [Select]
/flash/egServer/Dragonfly/Measurements/Data
The Content of this Directory:

Code: [Select]
Size   Filename
-----   ---------------------------------------------
788K 1xEVDORev4608ArbPlayback1.bin
788K 1xEVDORev96ArbPlayback1.bin
788K 1xEVDORevArbPlayback1.bin
 12K C2KRevFundamentalRandomPayload.bin
 12K C2KRevFundamentalZeroPayload.bin
1.4M iDENInOneSixthArbPlayback1.bin
 12K IS95RevAccessZeroPayload.bin
 12K IS95RevTraffic144FixedPayload.bin
 12K IS95RevTraffic144ZeroPayload.bin
 12K IS95RevTraffic96FixedPayload.bin
 12K IS95RevTrafficRandomPayload.bin
 12K IS95RevTrafficZeroPayload.bin

The Data is sent to the signal generator over a serial interface. I think that it should be possible to replace those Files. I'm not sure about renaming the menu options on the Device, i think you would have to recompile the gui .jar file to do that.

Hi guys, thanks for all the hard work on this SA! I've just picked one up in good working order and have been playing around, seems like an excellent unit for the money I paid.

I intend to do some more poking around at this box over the coming weeks and will post my findings here.

For now I have mirrored some of the useful files on my web server in case they ever disappear (as the firmware updates apparently have from Agilent's site...): http://www.gotroot.ca/e7495/ . Many thanks to those who found them.

Hi

Does any of you have the latest E7495B firmware update files ? They seem to have disappeared from Agilent website...

Also, do you know if there are some hardware options or all options user installable ?

Thanks !

Thanks for the firmware !!!  :-+

Do you know about the options ? Specifically is it possible to install option 240 if the unit didn't come with it ? (question before buying, I can't try...)

Yes, all the software options are hackable pretty easily. Read the thread, you need to hex edit one file and maybe fiddle around a bit.

Thanks. Wasn't sure if 240 was a software or hardware option.

EDIT: Here's the list of hardware vs software options from the service manual :

Over the time of approx 10 months my unit LCD developed delamination / deterioration
See both up left and bottom corners, and switch off picture of left up, it is between LCD layers...
Unit was stored over the summer in original bag within dark & dry and temperature was never more than 30-32 o C





This is the same unit picture from FEB 2015.



Unit is still good for use, but
now looking for spare screen
or whole broken unit with good LCD  :-BROKE

PS any lead on LCD type and producer is much appreciated  :-+
