Hello All,
I am using E4402B Agilent's Spectrum Analyzer.
I need to take screen-shot after every n mins and then again change the parameters, then take screen-shot save it on PC. I can save all the screen-shot on PC.
My Problem is i have kept my program in Loop "Changing Parameters, then saving the screen-shot" So many times in loop same screen-shot get saved and message on Spectrum analyzer appears as" File Already Exists"... SO what might be the reason??? After deleting that save file from Spectrum Memoray I wait for 5 sec and after changing the parameters i wait for 3.5 mis to take screenshot. But still this happens.. I hope anyone can tell me the solution...
Thanks in Advance,
Pals

It sounds like you’re using an automated program to pull screen images from the ESA to your PC and not using the internal memory or floppy drive at all. If that is the case, the ESA actually does still save the screen image on this phantom drive if you will called the R: drive before pulling it across the bus into your PC. The ESA uses a home grown operating system that tries to mimic some of the Windows ® file system features. Since the ESA is using a home grown operating system the internal memory can become fragmented over time and there is no defrag program that you can run. The assumption here is that you were successfully pulling screen images for some period of time and then this issue came up. If that is the case, you might have to clear flash memory, which essentially does a defrag process.
Clearing flash memory will erase the instrument firmware and any measurement personalities that you may have loaded. My advice would be to press the System, More, Show System keys on the front panel of your instrument. If the analyzer identifies option B72, Expanded Memory you can install the latest instrument firmware version A.14.04. If the analyzer does not have option B72, you can only upgrade to A.07.06. After you clear flash and install the instrument firmware hopefully this issue will not come up for a long time.
Here is the location you can get the firmware: http://www.agilent.com/find/esa_firwmare You will need (9) freshly formatted floppy disks. You should perform the long format on your PC. Do not format the disks on the ESA itself.
Here is the clear flash process:
Clearing Flash Memory:
________________________________________
Note: This is a procedure that should not be taken lightly. However, it is something that does need to be done in certain situations.
________________________________________
One thing to be aware of when doing this is that in addition to clearing the instrument you will also lose all measurement personalities and their license keys that you currently have. A list of the latest versions of all of the measurement personalities can found at www.agilent.com/find/esa_revisions . You will also need to have a complete list of the license keys that are installed in the instrument. You can press the System, More, More, Licensing, Show License and write down the 12 character license keys if the instrument has any licensed options or software. I recommend doing all of this before you start to clear the memory so that you know that you have everything needed to return the instrument to working order.
To clear the memory do the following:
1. Turn the instrument Off
2. Insert Disk #1 of your firmware installation disk set (ESA Loader)
3. Turn the instrument back On while holding down the following front panel keys for 10 second after pressing the "On" button: [ESC]-[Return]-[View/Trace]
4. The instrument will now clear it's flash memory and run the firmware loading program from the floppy disk once it has finished. This will take several minutes, so please be patient.
5. Follow the on-screen instructions to install the firmware and PowerSuite Utility
6. Restore the system defaults by pressing [System]{More}{Restore Sys Defaults}{Restore Sys Defaults}
I hope this was helpful -
