It didn't allow me.  :(

Thanks, it should be just a concatenation of other three images. It's not needed as you posted the other ones.

Now I played with the L4600 software for some time.

Good things:
* It does run on the E7495
* FM modulation is working.
* User-defined modulation files should work (I haven't tried it yet).
* FM analyzer is working.
* Source Level adjustment in the "Two port insertion loss" mode adjusts the amplitude smoothly above  -25dBm.

Bad things:
* The calibration is off.
* The generator is not working below 375MHz.
* GPS can't be used as a frequency reference (it's not even listed). I think it's the same problem jordi has on the L4600A.

The issue that was looking like a component failure appeared to be a pure software thing.
There is some SMBUS/Smart battery ugliness. Anyway, now I know quite a lot about this module.
I can help with diagnostics and repair.

I have an E7495B that refuses to work on batteries. I bought brand new batteries - 2 pcs Inspired Energy, type NI2040ED29 - from accutronics.co.uk . (The batteries were more expensive than the E7495B.)

When running on external power, everything works fine; the batteries are identified and charged - the battery information screen looks just fine with charging status and voltages correctly presented. The problem is, when booting up on battery power it passes the initial BIOS screens and then just powers off itself. Any information on how/where to rectify this would be most welcome.

Best regards,

Yes, the symptoms are very similar to what I have seen. However that's not enough to be sure.
Do you see any glitches while charging? For example, something's like incorrect charge % or battery leds change unexpectedly.
What happens to the leds while booting on battery?

200-cdmaOne/CDMA 2000 Analyzer
210 cdmaOne/CDMA 200 Over air test
220 Channel scanner
510 CW & Complex modulation signal Generator
600 Power Meter
700 T1 analyser

I have pulled off the Elgato file from egServer.

hope someone can help.

TIA

Hello Tia,

No, I don't think there is a premade file (we all had to mod ours). If you upload it, we can verify if is correct. When el gato is modified correctly (and installed), you must manually add the licenses by modifying the other file (forgot the name).
