How to use 34401 to get the voltage reading at 1000time/s sample rate

I am using 34401 to measure DC voltage, I want to sample the voltage at the rate of 1000 times per second. I am trying to get 450 readings at the speed, but the it takes me 1s+ to get it done, below is the configuration I made for this test

 

CONF:VOLT:DC

TRIG:SOUR BUS

TRIG:COUN 1

VOLT:NPLC 0.02

SAMP:COUN 450

TRIG:DEL 0.0006 

 

After sending above command sequence, I issue the command INIT followed by *TRG, then I send a FETC? to raise the event to PC, but I found it takes 1.8+s for the program to run into the event handler entry from the time point right before sending the *TRG command.

 

Can some one help to point out what's wrong with above command sequence?
