Menu Description
Amplitude
Amplitude can be expressed as Vrms, Vpeak, Vpp, dBV, dBu, and dBm for the analog generator.
Amplitude can be expressed as FFS, dBFS, or %FS for the digital and Bluetooth generator.
For a perfect sine waveform without any DC offset, Vpp is twice Vpeak and Vrms is equivalent to Vpeak/√2.
Frequency 1 Frequency 1 refers to the frequency for the first sine component.
Frequency 2 Frequency 2 refers to the frequency for the second sine component.
DC Offset DC Offset refers to the DC component of the waveform.
Ratio Ratio refers to the amplitude ratio of the second sine component over the first sine component.
Summation
Summation refers to the method to sum up two levels.
–RSS
The amplitude displayed is the Root Sum Square (RSS) summation result of the two levels. The analyzer will read the
same amplitude set at the generator regardless of tone ratio.
– Linear
The amplitude displayed is the linear summation result of the two levels. The level of each tone can be easily calculated
back from the tone ratio.
