While the terminology may not match yours (eg 2KHz) I believe what you 
seek is the functionality one gets when one includes 
"--enable-intervals" on the ./configure command line:

./configure --enable-intervals ...

That will enable the global '-b <burst size>' and '-w <burst interval>' 
options which can be used to pace the rate at which netperf does its 
thing.  By default, netperf will use the systems interval timer, and so 
is constrained to that granularity for the burst interval.  If you also 
include "--enable-spin" on the ./configure netperf will instead sit and 
spin until the interval is reached.

happy benchmarking,
