Trouble downloading the learn String LRN

I am using a 87352B USB to GPIB adapter, HP8753D VNA, VISA COM, and VB, and I am trying to download the learn string. The problem I am having is the header says the block should be 8000+ bytes and all I get ~3172 bytes? Is there a buffer somewhere that I have to increase? When I try to send the learn string back I get a block size error. I want to use the learn string for 2 purposes 1) to reset the state of VNA before testing starts and 2) to compare it to a previously downloaded string to see if the instrument state has changed.

Thanks for your help
