Operator Manual

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.)

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
200 Hz.
