VISA Read error--timeout expired

Highlighted

I am using an Agilent MXA N9020A Signal Analyzer and want to send a screen capture to my PC.  One of the steps involves loading the screen capture file contents from MXA local storage into memory using the MMEMORY command.  I'm getting a VISA return status of Hex 0xBFFF0015 "Timeout Expired" with the following command: MMEMORY:DATA? 'D:\TEST.PNG'.  Even with a 10000 byte file and a delay of 2 minutes the timeout persists.  I'm sure I must be missing something obvious and any help will be appreciated! 

 

I've attached the VI snippet.

 

Thanks in advance,

Nina

You should wire up the error wires between the VISA functions.

 

Should the commands you are sending have a termination character such as a carriage return, or line feed, or carriage return and line feed sent at the end of them?

 

10,000 bytes is a lot to request on the read.  Are you sure it is going to send you 10,000 bytes?  Is a termination character configured for this device that would end the read early if it received that character?
