Additional Specifications
The subsequent paragraphs provide additional specifications for the 5502A 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 5502A 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.

[1] The maximum frequency of the harmonic output is 30 kHz (10 kHz for 3.3 to 5 V on the Aux terminals). For example, if the
fundamental output is 5 kHz, the maximum selection is the 6th harmonic (30 kHz). All harmonic frequencies (2nd to 50th) are
available for fundamental outputs between 10 Hz and 600 Hz (200 Hz for 3.3 to 5 V on the Aux terminals).
Phase Uncertainty
................................................. 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
°
(from “Phase
Specifications”). Another example, the phase uncertainty of a 50 Hz
fundamental output and a 400 Hz harmonic output is 1 degree.
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) 90 Day Specifications” the single
output specification for 100 V, 100 Hz, is 0.039 % + 3 mV. For the dual
output in this example, the specification is 0.039 % + 6 mV as the
0.039 % is the same, and the floor is twice the value (2 x 3 mV).
AUX (50th Harmonic) Output:
100 mV, 5 kHz ................................................ From “AC Voltage (Sine Wave) 90 Day Specifications” the auxiliary
output specification for 100 mV, 5 kHz, is 0.15 % + 450
μ
V. For the
dual output in this example, the specification is 0.15 % + 900
μ
V as the
0.15 % is the same, and the floor is twice the value (2 x 450
μ
V).
