Shared Calibration Outputs
Both the Fluke 5520A and the Fluke 5522A feature an expansive sourcing envelope. For DC signals, both models provide voltage outputs from 0 to ±1020 V and current outputs from 0 to ±20.5 A. Their alternating current capabilities include AC voltage from 1 mV to 1020 V across a frequency range of 10 Hz to 500 kHz, and AC current from 29 µA to 20.5 A across a frequency range of 10 Hz to 30 kHz.
Available AC waveforms for both instruments include sine, square, triangle, and truncated sine waves. Both systems offer continuously variable resistance ranges up to 1.1 GΩ (or 1100 MΩ) and continuously variable capacitance output modes. Additionally, both units offer dual output capabilities, allowing simultaneous generation of two voltage outputs, or a simultaneous voltage and current output, with a phase resolution of 0.01°.
Hardware and Safety Variations
While sharing identical source limits, key differences exist in the physical interfaces and safety provisions. The Fluke 5522A is equipped with a dual display setup, utilizing a high-contrast backlit graphic LCD for menus and settings, alongside a segmented vacuum fluorescent display (VFD) to show primary output values. The Fluke 5522A also incorporates a built-in V-Guard reverse power protection system, which protects all voltage and current output terminals from external voltages up to 300 V peak.
There are also minor physical differences between the two units. The Fluke 5520A measures 432 mm in width, whereas the Fluke 5522A is slightly wider at 443 mm. Both units share a height of 178 mm and a depth of 473 mm.
Option Support and Simulated Power
For temperature calibration workloads, both models support thermocouple and resistance temperature detector (RTD) simulation. Thermocouple and RTD simulation resolutions are identical at 0.01 °C (or 0.01 °F). Both calibrators can also be configured with oscilloscope calibration options, supporting bandwidths up to 300 MHz, 600 MHz, or 1.1 GHz.
Simulated power capabilities are present on both systems. The Fluke 5522A delivers simulated power up to 20.9 kW when utilizing simultaneous voltage and current outputs, supporting a power factor range from 0 to 1 and harmonics generation up to the 50th harmonic. For specialized power quality calibration, the Fluke 5520A supports a dedicated power quality option model.
