Hi there,

I'm trying to save data to an usb device (memory stick). But I get the following error: *java.lang.NullPointerException: Unable to create writable storage device
I've tried each of the three usb slots and I formatted the memory stick (1GB) with fat, fat32 and ntfs. But everytime the same error...
I also tried a second memory stick.

Do I have to make a special folder on the stick? I didn't found anything about in the user manual.

Thanks,
Reto

Hi,

our company owns Agilent E7495B spectrum analyzer and when I try to "Print Screen" a get the following error (same as the OP here got): *java.lang.NullPointerException ... blah blah blah.

- I looked for a firmware upgrade but we already have the newest one.
- I have a PCMCIA card plugged in, which came with the unit.
- I set up saving all to PCMCIA.

When I go to Spectrum Analyzer mode and hit either "Save Data" or "Save State" the data is written to the card successfully (at least that's what the display is telling me)
But when I hit "Print Screen" a get an error message saying that the screen cannot be capture etc.

Anyone any suggestions? Am I doing something wrong or is it defective unit/card?

Thank you!

I will answer that question myself
Even though I had the latest firware in the unit I decided to re-flash it anyway and the error message is gone and I can again "Capture the Screen".
Everything else works fine too.

For some unknown reason the software in the unit must have got corrupted and it was giving me that error.
So whoever will experience this problem with any unit in the future can refer to this thread.

I have the same problem! The firmware can not be upgraded!

Now I am using a Agilent N1996A spectral analyzer.
Several month ago, it worked well. However, recently there are some problem with the USB Storage.
The words Java.lang nullpointer unable to create writable storage device was displayed on the screen, and the data cannot be saved to USB memory.

I have searched on the Agilent Discussion Forums, where the expert advised to upgrade the firmware.
I have tried, but the firmware can not be upgraded!

What should I do?
