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 (Sine Wave) Specifications” the single output specification for 100 V,
100 Hz, is 0.015 % + 2 mV. For the dual output in this example, the specification is 0.015
%
+ 4 mV as the 0.015 % is the same, and the floor is twice the value (2 x 2 mV).
AUX (50th Harmonic) Output:
100 mV, 5 kHz.......................................................From “AC Voltage (Sine Wave) 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).
