    self.urukul0_ch0.set_att(0.0)
    delay(1000*ms)
    try:
        self.urukul0_ch0.set(200*MHz)
        delay(30000*ms)
        #self.urukul0_ch0.sw.off()
    
    except RTIOUnderflow:
        print("Error for time")

I am wondering what problem occurs for artiq5,why no signal was found on the spectrometer,is there any wrong with my code?

You need to initialize the channel first, i.e. self.urukul0_ch0.init()
See kasli_tester for an example.

hello,sorry to interrupt you!I tried this code but still fail,what is the problem with artiq5?can you help me
