Figure 21: Advanced Peak Hold 
For the advanced peak hold function, there are the same settings for reset and signal slope available like 
for the peak hold function, see sections 7.3.2.1 Reset, page 38 and 7.3.2.2 Signal Slope, page 39.

This function works similar to the peak hold function, except it will search the signal for a minimum. 
7.3.5 Advanced Valley Hold 
This function works similar to the advanced peak hold function, except it will search the  signal for a 
local minimum.
