I'm communicating with the 81134A 3.35 Pattern/Pulse Generator over gpib. I'm trying to set channel 1 and 2 data pattern. The programming manual say I can go up to 8192 bits, and I am only trying to send 4640 bits, but it will not work. For some reason the device stops registering the command at around 2000 bits in length. I attached a shot of the manual page I'm looking at. Any ideas what is going on?
