X Volts (or Amps)
Figure 5-33, X Output in Volts or Amps
Shows the X output 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, with the instrument's reference phase adjusted for
maximum X output, the display would read 50.00 mV
Y Volts (or Amps)
Figure 5-34, Y Output in Volts or Amps
Shows the Y output 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, with the instrument's reference phase adjusted for
maximum Y output, the display would read 50.00 mV
