5 220A
Instruction Manual
1-2
selection switches are inside the 5220A. Refer to Section 4 of this manual for information
on how to properly set the line power switches.
Accessories available for use with the 5220A are listed and described in Table 1-1. The
rack mounting kits are designed for use with a standard 19-inch equipment rack. The
Model Y5020A is a precision current shunt recommended for use in calibrating the
5220A. Specify both model number and description when ordering accessories.

1-2. Specifications
Specifications for the Model 5220A are given in Table 1-2.
Table. 1-2. Specifications
Calibration Cycle All specifications are valid for a 180-day period at an operating
temperature of 20 °C to 30 °C and a relative humidity of 70 % or
less.
Basic
Transconductance 1 Siemen (1 ampere per volt)
Output Range 0 A to 20 A dc or rms ac (28.3 A peak)
Compliance Voltage ≥±4 V dc or 3 V rms ac (4.25 V peak)
DC Accuracy ±(0.025 % of output +1 mA)
AC Accuracy ±(0.05 % of output + 1 mA) from 30 Hz to 1 kHz, and ±(0.05 % of
output + 1 mA) x f from 1 kHz to 5 kHz, where f = frequency in kHz.
Short Term DC Stability Output changes less than ±(0.005 % + 200 µA) in 10 minutes, with
constant line, load, and temperature.
Short Term AC Stability Output changes less than ±(0.01 % + 500 µA) in 10 minutes, with
constant line, load, and temperature.
Harmonic Distortion and Noise ±(0.05 % of output ±1 mA rms) over frequency range of 30 Hz to 1
kHz and measured with a noise bandwidth of 300 kHz, ±(0.05 % of
output + 1 mA) x f from 1 kHz to 5 kHz, where f = frequency in kHz.
Temperature Coefficient ±(0.0025 % of output + 100 µA) per degree C above 30 °C or
below 20 °C.
Transient Recovery Output will settle to within 0.01 % of final value within 2 seconds
following a programmed change in output current or frequency
(10 ms for 5220A alone).
