Hi Ron,
Thank you! Managed to get it working. By any chance, you know how to change the
"delay" using python over time? I tried to use QT Entry GUI shown in the guided
tutorial, instead of if else function I tried doing for loop
def set_delay_amt(self, delay_amt):
c = 0
for a in range(0,5000):
for b in range(0,6000):
if b == 5999:
c = c + 1
t = c*0.001
delay_amt =
int(0.04*((3500*(t-2.5))**2 + 227322562.9)**(1/2.0)
self.delay_amt = delay_amt
Qt.QMetaObject.invokeMethod(self._delay_amt_line_edit,
"setText", Qt.Q_ARG("QString", str(self.delay_amt)))
Self.blocks_delay_0.set_dly(self.delay_amt)
I've tested the code for the one listed below and tested it out using python
shell, got the values I want.
c = 0
for a in range(0,5000):
for b in range(0,6000):
if b == 5999:
c = c + 1
t = c*0.001
delay_amt =
int(0.04*((3500*(t-2.5))**2 + 227322562.9)**(1/2.0)
Just that I not sure where to place it in the generated file. Thank you!

You should also change the Trigger Mode in the QT Time sink to Normal.

It's just a scaling issue. One sample of delay at 32 ksps is much longer in
time than one sample of delay at 10 Msps. Try the following changes.
1) Change the number of points in the QT GUI Time sink to 32768.
2) In the QT GUI range block, change the Stop value to 10000 and the Step value
to 100.

Hi Ron,
Thanks! It works for me too, but when I increase the samp_rate to 10e6, can't
see the delay.

It works here. Here's a small flow graph that I tested the delay block
operation with.

Hi Ron,
That means the Delay block is able to change as well, but why do I not see the
delay when simulating on the time sink?
Thanks in advanced!

If a block variable can be changed during run time, it will be underlined in
the properties dialog. For example, in the Multiply Const block, the variable
"Constant" can be changed.
[block]

Hi all,
Is it possible for me to create a QT GUI Range and put the ID in the Delay of
the delay block? I tried and the graph doesn't change.
