I would like to upgrade the size of the flash memory in an Agilent
E4411B spectrum analyzer because the upgrade (from 8MB to 16MB) is
required for the current firmware.

The upgrade involves replacing the 4MB flash SIMM with a 12MB SIMM.
It's option B72, Agilent part number E4401-60081. It is available
from Agilent for $300, but that's a lot to pay for 12MB of flash
memory!

It looks like it would be simple enough to expand the existing 4MB
SIMM if I could find two more Sharp LH28F320SKTD-L70 4MB flash chips.
Does anyone have any ideas on where I could buy two LH28F320SKTD, or
equivalent 4MB flash chips?

Good luck.
According to Agilent, this part is in protected status which means it is
no longer made and they bought all that they needed based upon projected
demand. That might explain the high cost.....Agilent's factory cost is
about $70 and a 3-4 times mark-up is typical in this industry.
The Mfg part number I found was LH28F320SKTD-ZR...not sure what the
suffix difference indicates.

Wow, I had no idea it was such a rare part. I guess I'll have to
decide if the upgrade is worth the cost.

Thanks,

I don't suppose anyone has a one or two old 4MB flash SIMMs sitting
around after doing an upgrade?

Hi Andy, there are a couple of hits for LH28F320SKTD-L70 on findchips.com
http://www.findchips.com

Allegedly 1200+ pcs. at
http://www.americaii.com/help/help_partsearch.shtml

I don't know whether they have a minimum order, though.
