Fundamental Voltages
Frequency NORMAL
[1] Terminals
10 to 45 Hz 33 mV to 32.9999 V 3.3 mA to 2.19999 A
45 to 65 Hz 33 mV to 1020 V
65 to 500 Hz 33 mV to 1020 V
500 to 1 kHz 330 mV to 1020 V
1k to 5 kHz 3.3 V to 1020 V
Phase uncertainty for harmonic outputs is 1 degree, or the phase uncertainty shown in "Phase
Specifications" for the particular output, whichever is greater. For example, the phase uncertainty of a 400
Hz fundamental output and 10 kHz harmonic output is 10 degrees (from "Phase Specifications"). Another
example, the phase uncertainty of a 60 Hz fundamental output and a 400 Hz harmonic output is 1 degree.
[1] The maximum frequency of the harmonic output is 10 kHz. For example, if the fundamental output
is 5 kHz, the maximum selection is the 2nd harmonic (10 kHz). All harmonic frequencies
(2nd to 50th) are available for fundamental outputs between 10 and 200 Hz.
Example of Determining Amplitude Uncertainty in a Dual Output Harmonic Mode
What are the amplitude uncertainties for the following dual outputs?
NORMAL (Fundamental) Output: 100 V, 100 Hz
From "AC Voltage (Sinewave) Specifications" the single output specification for
100 V, 100 Hz, is 0.04% + 6.6 mV. For the dual output in this example, the specification
is 0.04% + 13.2 mV as the 0.04% is the same and the floor is twice the value (2 x 6.6 mV).
AUX (50th Harmonic) Output: 100 mV, 5 kHz
From "AC Voltage (Sinewave) Specifications" the auxiliary output specification for
100 mV, 5 kHz, is 0.15% + 450 mV. For the dual output in this example, the specification
is 0.15% + 900 mV as the 0.15% is the same and the floor is twice the value (2 x 450 mV).
