1-29. Additional Specifications
The following paragraphs provide additional specifications for the 5500A Calibrator ac voltage and ac current functions.
These specifications are valid after allowing a warm-up period of 30 minutes, or twice the time the 5500A has been turned
off. All extended range specifications are based on performing the internal zero-cal function at weekly intervals, or when
the ambient temperature changes by more than 5 °C. (See Chapter 4, Front Panel Operations in the 5500A Operator
Manual.)

Same % of output as the
equivalent single output,
but twice the floor adder.
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 2
nd
harmonic (10 kHz). All harmonic frequencies (2
nd
to 50
th
) 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 (50
th
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).
