The amplifier card is calibrated in factory together with the arbitrary waveform generator that it is used with. The calibration values are stored inside the arbitrary waveform generator card.
The amplifier option is available as short PCI Express (PCIe) card, as PCI card as well as 3U CompactPCI card.
The analog ground of the amplifier card is completely isolated from the computers ground. Under normal circumstances and in usual computers this is the best solution to avoid unwanted ground loops. If for any reasons it appears to have problems like oscillation on the outputs, there is an additional "ground connect" jumper.
This is an add-on product for Spectrum's own line of instrumentation product. This product is therefore solely sold together with one of these and not separately.
