Hi,
Im designing a simple BPF with two first order poles and I need to measure the Bandwith (the poles are placed at around 100 and 200 hertz).

With the following statement I get the Maximum gain(between 50Hz to 1000Hz) :
.measure ac maximo max V(Vout) from = 50 to = 1000

With the calculated gain I want to estimate the poles with the trigger and target function, but I dont know why I cant use maximo as a parameter:
.measure ac bandwidth trig v(Vout) val = 0.71*maximo rise=1
+ targ v(Vout) val = 0.71*maximo fall=1


How would you solve this?
Thanks!
 

Re: Measure Bandwith with T-spice or Hspice

I can use H-Spice as well, any ideas?
Thanks
