Dear all:

1. I write measure criterion as follow:
.meas tran dr when v(vcop)=v(vcon) td=4.8u rise=2
.meas tran df when v(vcop)=v(vcon) td=4.8u rise=3
.meas trq param='df-dr'

and .lis report is show me 100.25Mhz
but I need more accuracy like 100.25341Mhz
How can I do ?
2. I want to measure VCO frequency from 3us to 5us ,
the description in item 1 is right ?

Thanks
 

.option numdgt=7 measdgt=7

Click to expand...
What about one ".meas" statement:
.meas tran trq trig v(vcop, vcon) val = 0 td = 4.8u rise = 2
+ targ v(vcop, vcon) val = 0 td = 4.8u rise = 3
