4-19. RMS Versus p-p Amplitude
The 5520A Calibrator ranges for sinusoidal ac functions are specified in rms (root-mean-
square; the effective value of the wave form). For example, 1.0 to 32.999 mV, 33 to
329.999 mV, 0.33 to 3.29999 V and so forth. The sine wave outputs are in rms, while the
triangle wave, square wave, and truncated sine wave outputs are in p-p. The relationship
between p-p and rms for the non-sine wave types are as follows:
• Square wave p-p x 0.5000000 = rms
• Triangle wave p-p x 0.2886751 = rms
• Truncated Sine wave p-p x 0.2165063 = rms
