Skutils is in beta, please contact support@skutek.com with bugs, issues, and questions

Connecting to your FemtoDAQ

[ ]:

# Connect to your FemtoDAQ
url = "vireo-000019.tek"  # skutils.FEMTODAQ_USB # for digitizers connected via USB, other replace with URL or IP
digitizer = skutils.FemtoDAQController(url, skip_version_check=True)

digitizer.stop()

print(digitizer.summary())

# set trigger and pulse height windows
for chan in digitizer.channels:
    digitizer.setInvertADCSignal(chan, True)
    digitizer.setEnableTrigger(chan, True)
    digitizer.setDigitalOffset(chan, 700)
    digitizer.setTriggerSensitivity(chan, 50)
    digitizer.setTriggerEdge(chan, "rising")


# Save 512 samples per waveform

digitizer.start("continuous")

print("grabbing event to inspect")
inspection_event = digitizer.inspectNextEvent(2)
skutils.quickPlotEvent(
    digitizer,
    inspection_event,
    fig_title="Inspected Event for Pocket Pulser with 50ns delay on Ch1",
    channel_titles={0: "Pocket Pulser", 1: "Delayed by 50ns"},
)
digitizer.stop()
