Hello, maybe one of you has an idea about the following topic. We want to use the Zotino as a frequency generator in the kilohertz range. For this we set a periodeic output of 1V with duration t. Between the pulses there is a delay also of t (see attached script). We now notice that the amplitude of the output signal decreases for higher frequencies (also in the attached folder).
Why is this the case?
Record a sequence set for the sinara zotino (two pulses with amplitude 0
and 1). The script can be used to create a alternating output signal. The
signal frequency depends on the delay between both outputs. The maximal
frequency is around 200 kHz for a delay near 1.6 us.
Record the sequene set.
time = self.time
volt0 = self.zotino0.voltage_to_mu(0)
volt1 = self.zotino0.voltage_to_mu(1)
for i in range(500):
delay(time*us) # minimum for signal is 1.5*us
Reset the core device, load the pre-defined sequence set and play this
pulse_handle = self.core_dma.get_handle("pulses")
