Title: Hold option requested
Post by: eldoradofm on September 05, 2011, 11:57:23 pm

I am measuring some different processor settings and i'd like to see an option for Deviation MAX that i can hold the MAX value. Like a checkbox next to it with MAX Hold. Now i have to look at the screen all the time while playing the test song. I know there's a MAX Hold function on the device itself but i can't define start and stop for it. Can you add this checkbox?

If you download actual rev. 7, you may do it using simple script:

Code: [Select]

setmode(0)
set(amh)
set(start,%time)
repeat:
sleep(1)
send('?X')
if (%tsmaxhold>%amh)
 statusbartext(Absolute MAX Hold since %start: %tsmaxhold at %time)
 set(amh,%tsmaxhold)
 endif
goto(repeat)
However interpret a result of this function with care as one number can never describe a complex process the fm modulation is. Use the histogram everytime it's possible. One peak above limit during a long period does not automatically mean that authority will visit you  ;)
