The 5520A Multi-Product Calibrator sources direct voltage and current, alternating voltage and current with multiple waveforms and harmonics, two simultaneous voltage outputs or voltage and current to simulate dc and ac power with phase control, resistance, capacitance, thermocouples and RTDs. The 5520A can also measure thermocouple temperature, humidity (with probe) and pressure using one of 28 Fluke Calibration 700 Series pressure modules. Three options add the capability to calibrate oscilloscopes up to 1.1 GHz. And the 5520A-PQ Power Quality Option enables the 5520A to calibrate power quality instrumentation to the standards of the IEC and other regulatory agencies.

Wide workload coverage

Because it can calibrate so much of your workload, the 5520A makes your calibration investment go further. Instead of several instruments to purchase, maintain and transport, the 5520A combines all the capability in one compact, portable and affordable tool.

Easy to use

Though it can do a lot, the 5520A is simple to use. Its front panel is logically arranged and clearly labeled. And its bright LCD displays provide all the information you need at a glance. The 5520A is so intuitively easy to use, you’ll seldom need to consult the manual. For almost every operation, your hand moves naturally from left to right. Values ​​are entered on the calculator-style keyboard. Output values ​​can be stepped up or down easily in even decade multiples (1-2-5 sequence in scope mode) using the multiply and divide keys. You can even view the uncertainty for any value at the press of a key.

Versatile and flexible

The basic 5520A can tackle a tremendous amount of work. And as your workload changes, your 5520A can adapt. Three options are available to address the calibration requirements of oscilloscopes. If your workload is made up mostly of oscilloscopes up to 300 MHz bandwidth, the 5500A-SC300 option is an affordable solution. If your workload extends to 600MHz, the 5500A-SC600 adds complete, powerful oscilloscope calibration capability to your 5520A. The 5520A-SC1100 option enables the 5520A to calibrate all of your oscilloscopes up to 1.1 GHz with rise times to 300 ps – even 125 ps with the 5800A/TDP tunnel diode pulser option. Any of these options can be fitted at time of purchase, or added later as your needs change.

If three-phase power measurement tools are part of your workload, the 5520A can greatly simplify the task. Its phase locking capability makes it possible to “lock” three 5520As together to simulate three phase power up to nearly 21 kW with multiple waveforms, harmonics and precise phase control. Using this capability, you can also “sum” the current outputs of multiple 5520As to source 100A or more to directly verify current clamps or power transformers.

Portable and rugged

The 5520A isn’t limited to the controlled environment of the calibration lab. It’s made to go where the work is. It’s compact so it’s easy to take it where the work is. Its rugged construction means you don’t have to treat it like a delicate lab instrument. And it’s self-contained. No additional test pad is required.
