Dear all:

My sequence as bellow in Command Expert 
If ARB file size small than 4MB, it's workable
But when I load over 4MB, I'll get error message:
VI_ERROR_TMO: A timeout occurred | SCPI connection attempt timed out | Timed out while trying to query instrument errors"

How to fix the issue? thanks

viOpen(rm, "GPIB0::10::INSTR", VI_NULL, VI_NULL, &v33522B);
viPrintf(v33522B, "*CLS\n");
viPrintf(v33522B, "*RST\n");
viPrintf(v33522B, ":SOURce1:DATA:VOLatile:CLEar\n");
viPrintf(v33522B, ":MMEMory:LOAD:DATA1 \"%s\"\n", "USB:\\Noise Pattern\\20kHz_Big.arb");
viPrintf(v33522B, ":SOURce1:FUNCtion:ARBitrary \"%s\"\n", "USB:\\Noise Pattern\\20kHz_Big.arb");
viPrintf(v33522B, ":SOURce1:FUNCtion %s\n", "ARB");
viPrintf(v33522B, ":OUTPut1 %@1d\n", 1);
