 Transconductance: 1 siemens (1 A per volt) 
 Output range: 0 to 20 A dc or rms ac 
 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 is frequency in kHz 
 Short-term stability dc: output changes less than ±(0.005% + 200 μA) in 

10 minutes, with constant line, load, and temperature 
 Short-term stability ac: output changes less than ±(0.01% + 500 μA) in 

10 minutes, with constant line, load, and temperature 
 100, 110, 115, 120, 200, 220, 230, 240 Vac +10%; 50-60 Hz operation 
 Weight: 50 lb 
    The 5220A Transconductance Amplifier allows for the calibration of AC 

or DC meters and
 shunts and current functions of digital multimeters that measure up to 20 

A. A known input voltage of 1 to 20 volts 
produces a known output current of 1 to 20 amps. The 5220A is designed to 

be 
controlled by the 5700A or 5100B series calibrators but may be 
driven by any other voltage source.
