PNA-X RF turn-on time measurements

Hello PNAX users,

I am hoping to use my PNAX to determine turn on/off response times of a MMIC amplifier.  I have a CW sweep setup with the sweep externally triggered by the enable line of the MMIC and measure the output power when driven from Port 1 (B,1).  The IFBW is set to 15 MHz.  The best sample period I can achieve is ~50 ns.  Are there any settings I can change to improve this sampling rate - 50 ns is a little coarse for my application, if I can achieve 20-25 ns, this would really help me.

Thanks

andy
