Service Manual
1-8. Specifications
The following tables list the 5520A specifications. All specifications are valid after allowing a warm-up period of 30 minutes, or twice the time the 5520A has been turned off. (For example, if the 5520A has been turned off for 5 minutes, the warm-up period is
10 minutes.)
All specifications apply for the temperature and time period indicated. For temperatures outside of t cal
±
5
°
C (t cal
is the ambient temperature when the 5520A was calibrated), the temperature coefficient as stated in the General Specifications must be applied.
The specifications also assume the Calibrator is zeroed every seven days or whenever the ambient temperature changes more than 5
°
C. The tightest ohms specifications are maintained with a zero cal every 12 hours within
±
1
°
C of use.
Also see additional specifications later in this chapter for information on extended specifications for ac voltage and current. The dimensional outline for the 5520A
Calibrator is shown in Figure 1-3.

99%
Specification Confidence
Interval
[1] After long periods of storage at high humidity, a drying out period (with the power on) of at least one week may be required.
[2] For optimal performance at full dual outputs (e.g. 1000 V, 20A) choose a line voltage setting that is
±
7.5% from nominal.
[3] The DC Current ranges 0 to 1.09999 A and 1.1 A to 2.99999 A are sensitive to storage temperatures above 50 °C.
If the 5520A is stored above 50 °C for greater than 30 minutes, these ranges must be re-calibrated. Otherwise, the
90 day and 1 year uncertainties of these ranges double.

[2] Applies for a 4-WIRE compensation only. For 2-WIRE and 2-WIRE COMP, add 5 µV per Amp of stimulus current to the floor specification. For example, in 2-WIRE mode, at 1 k e
, the floor specification within 12 hours of an ohms zero cal for a measurement current of 1 mA is:
0.002 e
+ 5 µV/1 ma = (0.002 + 0.005) e
= 0.007 e
[3] For currents lower than shown, the floor adder increases by:
Floor (new) = Floor (old) XImin/Iactual.
For example, a 50 µA stimulus measuring 100 e
, has a floor specification of: 0.0014 e
X 1 mA/50 µA = 0.028 e
, assuming an ohms zero cal within 12 hours.

[1] Max Distortion for 100 kHz to 200 kHz. For 200 kHz to 500 kHz, the maximum distortion is 0.9% of
output + floor as shown.
[2] Duty Cycle: Currents < 11 A may be provided continuously. For currents > 11 A, see Figure 1-4. The
current may be provided 60-T-I minutes any 60 minute period where T is the temperature in °C (room
temperature is about 23
°
C) and I is the output current in Amps. For example, 17 A, at 23
°
C could be
provided for 60-17-23 = 20 minutes each hour.
[3] For compliance voltages greater than 1 V, add 1 mA/V to the floor specification from 1 kHz to 5 kHz.
[4] For compliance voltages greater than 1 V, add 5 mA/V to the floor specification from 5 kHz to 10 kHz.

1-22. Calculating Power Uncertainty

Because there are an infinite number of combinations, you should calculate the actual ac power uncertainty for your selected parameters. The method of calculation is best shown in the following examples (using 90-day specifications):
