Tips: Function signal generator frequency, output impedance, and output amplitude.
- Frequency is also called frequency resolution, is the minimum adjustable frequency resolution, which is the smallest time increment that can be used when creating a waveform. Frequency accuracy is the deviation between frequency value and true value displayed by signal source, it is usually expressed by relative error.
- Output impedance of function signal generator refers to the equivalent impedance of signal source from the output end. For example, output impedance of a low-frequency signal generator is usually 600Ω, the high-frequency signal generator is usually 50Ω, and the television signal generator is usually 75Ω.
- Output amplitude is generally expressed by voltage or decibel, which refers to the effective range of output signal amplitude. In addition, the output amplitude reading of function signal generator is defined on the output impedance matching condition, so the problem of output impedance matching must be paid attention to.
The series of function signal generators can modulate AM/AF internally and externally, have linear and logarithmic frequency sweep functions. Frequency range 0.1Hz~2MHz/3MHz/5MHz for selection, built-in 0.1Hz-30MHz frequency counter. It can output 7 waveforms including sine wave, square wave, triangle wave and ramp wave and others.
