how to measure bursted current with 66319d

I'm trying to accurately measure the bursted current of a GSM Power Amplifier using an Agilent 66319D mobile communications DC source.  I would like to trigger on the current burst, then delay 150uSec and read the average current over the next 400uSec.  The user manual says that this type of measurement is not possible using the front panel, only through programming.  I tried sending the following commands using labview, so I can make a triggered reading with a delay, but I can't seem to get a stable current reading:

INIT:NAME ACQ
SENS:SWE:TINT 46.8e-6;POIN 100
TRIG:ACQ:SOUR INT
SENS:FUNC "CURR"
TRIG:ACQ:LEV:CURR 1
TRIG:ACQ:SLOP:CURR POSITIVE
SENS:SWE:OFFS:POIN 99

and then I try to read the current using

MEAS:CURR:HIGH?

Is there something that I'm doing wrong in the above commands, or is there a better way to make this measurement?
