Query unterminated error in ENA read bandwidth function

I am trying to read bandwidth data from ENA equipments (E5062A).
The software I used is Labview 2011, the interface is GPIB. 
the configuration is:
marker1 tracking is ON
marker1 searching is MAX
bandwidth is ON
bandwidth value is -3db
Notch is off

all those commands are setup correctly.

When I try to read the bandwidth data with the command  of :CALC1:MARK1:BWID:DATA?, The network analyzer always shows "Query unterminated".
Please help me to figure out what's going on, or send me a demo code.
BTW, I send many commands to network analyzer, all of them are no any problem, except the command of reading bandwidth and read notch. is there any special things that I need setup?
Thanks a lot.
