Power meter speed

Hello,
I have not worked on the project that used the power meter in a while, but here is how I left it. I was trying to automatically calibrate an amplifier by adjusting the level of the input signal and using the power meter to observe the output power level. What I observed is that the power meter took a long time to accurately measure the power level, which increased the time I had to wait to get a correct power measurement. When the amplifier was at low power levels, the time did not make a difference, but at high power levels the amplifier could/would/did overheat and bad things did happen to the amplifier. Unfortunatley that project was canceled before I was able to come up with a fix.
I have also used MEMS before and you need to be aware of the scenario that I had, make sure that you do not blow something up because the time to get a accurate power level from the meter exceeds the duration that your device can sustain a power setting before it goes up in smoke. You may have to have a really nice cooling scheme for your MEMS device so that it does not burn up while you are waiting for the meter to give you a accurate power reading. If you have any other questions, please feel free to reply to this posting.
Regards,
Kaspar
