I would like to measure delay on signal "gap" simulated on two temp -40 and 125 with "trigger" option like:
dly_fr=delay( v("gap") 0.75 1 "falling" v("gap") 0.75 2 "rising" 1 1 t "trigger")
I am getting results like:
time delay(v("gap" delay(v("gap"
temp -40 125
17.8748u 38.4359u 7.67508u
56.3107u 9.60973u 38.4348u
65.9204u 38.4462u 9.60979u
104.367u 9.60927u 38.4452u
but I am expecting results something like:
17.8748u 38.4359u 38.XXXXu
56.3107u 38.XXXXu 38.4348u
65.9204u 38.4462u 38.XXXXu
(bold are expected values which also could be measured manually)
Signal shape is:
___ ___ ___ ___
___| |___| |_____________| |___| |________ < fr >
and I would like to measure value fr.
How can I correctly measure value fr? What caracters 1 1 t in the command line (marked bold) mean?
Which subversion are you using? In recent versions that I've tried, ViVA uses the newer keyword argument form of delay() which is much clearer to see what the arguments mean because they are passed by name rather than order.
The subversion can be found by doing Help->About... in the CIW.
In reply to Andrew Beckett:
I am using version IC6.1.5-64b.500.10
In reply to jerry124:
If you build the expression in that version (using the calculator) you'd get the newer keyword argument version of the function - for example:
delay(?wf1 v("gap" ?result "tran"), ?value1 0.75, ?edge1 "falling", ?nth1 1, ?td1 0.0, ?wf2 v("gap" ?result "tran"), ?value2 0.75, ?edge2 "rising", ?nth2 2, ?td2 0.0 , ?stop nil, ?multiple nil)
which is much clearer as every argument is named. I did a bit of digging, and the ordered arguments are in this order (we seem to have removed this from the documentation):
wf1 value1 nth1 edge1 wf2 value2 nth2 edge2 period1 period2 multiple xName
The default is that the second edge is relative to time, rather than the first edge.
So I believe your expression is equivalent to:
delay(?wf1 v("gap" ?result "tran"), ?value1 0.75, ?edge1 "falling", ?nth1 1, ?td1 0.0, ?wf2 v("gap" ?result "tran"), ?value2 0.75, ?edge2 "rising", ?nth2 2, ?td2r0 0.0 , ?stop nil, ?period1 1 ?period2 1 ?multiple t ?xName "trigger" )
This means that:
It's not clear to me if you really want the ?multiple occurrences or not.
So my recommendation would be to try building the expression in the calculator and check to see what you're getting, rather than using this positional argument version (I even checked back in IC5141 and the keyword argument version is documented there too).
