Our E4440A won't power on, so it needs to go out for service. Unfortunately there is probably some proprietary info on the drive which needs to come off. What's the best way to handle this?
- place the drive in another E4440 (which we have) and scour the drive
- place it in a computer of some type to access it
- get another OEM drive (if possible)
- ???
Thanks in advance

Unlike a Windows-based machine, the E4440A PSA Spectrum Analyser does not have a discrete physical hard drive. Data is stored in a flash memory module on the processor (typically 48MB or 64MB capacity), or possibly on the option 115 Expanded Memory flash board (capacity 512MB) if present.
Normally any user files (trace files, state files, screen images, etc) can be moved either manually one at a time to a formatted disk in the inbuilt floppy drive, or more usually remotely over one of the interface ports (GPIB, LAN or serial).
The fact that your unit will not power up precludes either of these methods, so if you really need to remove the data, you will need to physically remove the flash modules. The option 115 board is fairly straightforward, as it is an easily removed CompactFlash card that slots into the top of the A39 USB/Memory board, accessible by removing the unit's outer dress cover, and inner board cover.
The processor flash is more problematic: the Digital IF board and interface or memory boards need removing to allow the processor to be removed.
Once the processor is removed, you will see the flash memory board is secured to the processor on 4 plastic stand-offs, and much care needs to be taken to avoid damage during removal (there is another memory module also mounted on the processor, but this is volatile RAM, so does not store any data).
You will need to alert the service center to the fact that the unit now lacks any flash memory, as this will need to be temporarily replaced and firmware files reloaded to allow the analyser to be functionally verified once repaired.
Alternately, it may be simpler to arrange for a Keysight Field Engineer to perform a repair on-site.
I am assuming the unit simply needs a power-supply replacement, but of course the fault could lie elsewhere. This is best discussed with your local Keysight Customer Service Center.
I hope this helps. Regards, Simon C, on behalf of Keysight Technologies UK ltd.
