I'm starting to work with my redpitaya, and so far, everything is looking great. For the begining, I'm trying to send a signal on an analog output with an external trig. This is inspired by this example from the main page.
https://redpitaya.readthedocs.io/en/lat ... -exm3.html
All is neat and clean until I ramp up the trigger frequenc. At 5Hz, the redpitaya don't follow all the trig. 5Hz seems quite a low frequency so Im quite sure this is my way of commanding the board that is wrong.
Here is my python code.
Code: Select all
import redpitaya_scpi as scpi
import sys
wave_form = 'sine'
freq = 100
ampl = 1
rp_s = scpi.scpi(sys.argv[1])
rp_s.tx_txt('ACQ:DEC 1')
rp_s.tx_txt('ACQ:TRIG:LEVEL 1000')
rp_s.tx_txt('ACQ:START')
rp_s.tx_txt('GEN:RST')
rp_s.tx_txt('SOUR1:FUNC ' + str(wave_form).upper())
rp_s.tx_txt('SOUR1:FREQ:FIX ' + str(freq))
rp_s.tx_txt('SOUR1:VOLT ' + str(ampl))
rp_s.tx_txt('OUTPUT1:STATE ON')
while 1:
rp_s.tx_txt('SOUR1:BURS:NCYC 2')
rp_s.tx_txt('SOUR1:BURS:STAT BURST')
rp_s.tx_txt('SOUR1:TRIG:SOUR EXT_PE')
rp_s.tx_txt('ACQ:START')
rp_s.tx_txt('ACQ:TRIG EXT_NE')
while 1:
rp_s.tx_txt('ACQ:TRIG:STAT?')
status = rp_s.rx_txt()
if status == 'TD':
break
Code: Select all
status = rp_s.rx_txt()
