Channel Toolbar Channel 1 & 2 Configuration(Trigger Configuration)
Trigger Mode: Normal – triggered on specified condition Auto – triggered on trigger condition, self starts in 2 seconds None – the acquisition is started without a trigger Channel Toolbar Channel 1 & 2 (Trigger Configuration)
Source: Channel 1 Channel 2 Digital AWG – 1 AWG – 2 Analyzer Patterns External – 1 External - 2 Channel Toolbar Channel 1 & 2 (Trigger Configuration)
Type of Trigger: Simple – is an edge trigger where the filter, hysteresis, and holdoff parameters are configured automatically. Level is set to 10% of the selected trigger channel range Channel Toolbar Channel 1 & 2 (Trigger Configuration)
Type of Trigger: Edge + slope-condition control Channel Toolbar Channel 1 & 2 (Trigger Configuration)
Type of Trigger: Pulse, will trigger if pulse has a smaller/larger length than the one set by the user. Channel Toolbar Channel 1 & 2 (Trigger Configuration) Set for Less then 200 usec.
Type of Trigger: Pulse, will trigger if pulse has a smaller/larger length than the one set by the user. Channel Toolbar Channel 1 & 2 (Trigger Configuration) Set for more then 200 usec.
Type of Trigger: Transition - the transition time of a signal as compared with a specified length Channel Toolbar Channel 1 & 2 (Trigger Configuration)
Type of Trigger: Transition - the transition time of a signal as compared with a specified length Channel Toolbar Channel 1 & 2 (Trigger Configuration)
Trigger Hysteresis – low and high leveles are determined to avoid bouncing caused by signal noise and also to specify the transition trigger conditions, 20 volts to 1mv and zero volts in 1 -2 -5 steps Channel Toolbar Channel 1 & 2 (Trigger Configuration)
Trigger Hysteresis Channel Toolbar Channel 1 & 2 (Trigger Configuration)
Trigger Holdoff –a adjustable time period during which the oscilloscope will not trigger . this is useful when triggering on complex waveform shapes, so the oscilloscope triggers only on the first eligible trigger point. Time range from 1 hour to 100nsec., in 1 – 2 – 5 steps and zero sec. Channel Toolbar Channel 1 & 2 (Trigger Configuration)
Options: General, Display, Colors, Configuration Channel Toolbar Channel 1 & 2 (Options Configuration)
Main Toolbar F. F. T. function FFT View – plots amplitude against frequency, it shows the signals in the frequency domain as opposed to the time domain
Arbitrary Waveform Generator • the ADK Leads (Analog Discovery Kit) • Function Generator operation • Oscilloscope use
Leads we will be using today Waveform Gen-1 (yellow) to Scope ch-1 (orange) Waveform Gen-1 common gnd. (black) to Scope ch-1 neg. (orange/white)
Analog Discovery BNC Adapter Board Allows the use of standard BNC-terminated test leads & probes on your Analog Discovery Selectable AC and DC coupling to oscilloscope probes Selectable 50-ohm or 0-ohm output impedance on Arbitrary Waveform Generator (AWG) channels
