Querrying info timeout

Hello,

I'm trying to write a C program to automate some tests and generate a test report. I'm using the N9000A signal analyzer.
My C program can send SCPI commands just fine but whenever I try to query something, it doesn't work, I get a timeout error.

To test the commands I use the Keysight Connection Expert software and send them via USB.

Here's an example:
------------------------------------------------------------------------------
:CALC:MARK:FUNC:BAND:SPAN?
! VI_ERROR_TMO: A timeout occurred
Visa ErrorCode: 0xBFFF0015 (-1073807339)
------------------------------------------------------------------------------

I also noticed that when I try this command :CALC:MARK1:FUNC:BAND:SPAN 500 kHz the signal analyzer says "Undefined header:CALC:MARK"

Thank you in advance for your help.

Kevin
