The ICS-660B is a 4-channel, 14-bit, 105 MHz/ch., short PCI DAC board. The ICS-660B includes a large swing buffer that can be operated in continuous, one-shot or loop mode, the latter being ideal for periodic waveform generation. All channels are simultaneously updated and multiple boards can be synchronized. In addition to a fast PCI interface, the ICS-660B also includes a 400 MBytes/s FPDP II input port for rapid data transfer. The ICS-660B can be fitted with an optional, programmable, digital modulator daughter card (DC-60-M2) for radar and wireless transmit operations. Transmit waveforms can be supplied at a much lower rate, since the modulator performs the up-conversion to IF.
