The 2558A is a low-cost, high-precision instrument capable of outputting a wide range of AC voltages and currents for the calibration of electric meters and other devices. In terms of accuracy and other performance characteristics, this new model is a significant upgrade from our previous model, the 2558 AC voltage current standard, which was introduced in 1979 and discontinued in 2003. Providing output ranges of 1.00 mV to 1200.0 Volts AC, and 1.00 mA to 60.00 Amps AC makes the 2558A the product of choice for the cost effective calibration of AC analog meters and other AC measuring instruments. Front panel controls and various computer interfaces enable the 2558A to be intuitively operated manually or controlled by an ATE system.

The FG400 easily generates basic, application specific and arbitrary waveforms with a sine wave frequency range of .01 µHz to 30 MHz.  Output waveforms consist of Sine, Square, Pulse, Ramp, Parameter-variable, Noise (Gaussian distribution), DC and Arbitrary.  This unit includes isolated outputs that allow the user to use it in the development of floating circuits, like motor drives, inverters, power supplies and other power electronic devices.  In addition, multiple units can be synchronized together to generate up to 12 phases of output.
