The signal generator and oscilloscope are mainly connected through BNC coaxial cablesDirect connection, which means connecting the output port of the signal generator to the input channel of the oscilloscope. The following are detailed connection steps and operation points:
Preparation work before connection
Before connecting, it is necessary to ensure the safety of the device and prepare suitable connecting wires:
Equipment inspectionConfirm that the signal generator and oscilloscope are turned off, and check if the power and ground wires are well connected to avoid short circuits or electrostatic interference.
Wire selection: UseBNC interfaceCoaxial cable (such asRG58Or similar models), due to itsimpedance matchingFeatures can reduce signal attenuation and interference. If high impedance circuits need to be measured, they can be used with a 10X attenuation probe.
logistics linkInsert one end of the BNC cable into the output port of the signal generator (usually labeled as "OUTPUT" or "OUT"). Insert the other end into any oscilloscopeinput channel(such as CH1 or CH2), ensure that the interface is tightened to avoid poor contact.
Grounding treatmentIf a probe is used, the grounding clip of the probe needs to be connected to the grounding terminal of the signal generator or the circuit grounding point to eliminateCommon mode noise
After the connection is completed, it is necessary to configure the signal generator and oscilloscope separately:
Signal generator settingsAfter turning on the power, select the waveform type (such assine wave、square waveEtc.). Settingsfrequency、amplitude（Peak to peak voltage Vpp）AndDC offset(usually initially set to 0V).
Oscilloscope settingsSelect the corresponding input channel and set the coupling mode toDC coupling(to display the complete signal) orAC coupling(Only observe the communication component). adjustvertical sensitivity(Volts/Div) andtime reference（Time/Div）， Make the waveform clearly displayed on the screen. Set the trigger mode toedge-triggered(such as rising edge), and adjusttrigger levelTo stabilize the waveform at the midpoint of the signal amplitude.
