1-23. Additional Specifications
The following paragraphs provide additional specifications for the 5520A 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 5520A 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] With REF CLK set to ext, the frequency uncertainty of the 5520A is the uncertainty of the external
10 MHz clock ± 5 µHz. The amplitude of the 10 MHz external reference clock signal should be
between 1 V and 5 V p-p.
