MAG Volts (or Amps)
Figure 5-35, Magnitude Output in Volts or Amps
Shows the signal magnitude, where magnitude =
√
((X output)
2
+ (Y output)
2
),
directly in terms of volts or amps (depending on whether voltage or current input
mode is selected). Hence if the sensitivity setting were 100 mV and a 50 mV signal
were applied, regardless of the setting of the instrument’s reference phase, the display
would read 50.00 mV
Noise in Volts or Amps per Root Hertz
Figure 5-36, Noise Output in Volts or Amps per Root Hertz
Shows the noise accompanying the signal, in a noise bandwidth defined by the setting
of the output filter time constant, where it is assumed that the noise is Gaussian. Note
that the noise floor of the instrument is 2 nV and so the output value will always be
greater than this.
