German manufacturer Spectrum has released the M4i.445x-x8, the first card in its M4i series of high-speed PCI Express digitizers capable of delivering a synchronous sampling speed of 500 Msamples/s with 14-bit A/D resolution. The M4i.445x-x8 provides a signal bandwidth of 250 MHz, two or four input channels, and 4 Gbytes of onboard memory as standard.
A PCI Express x8 Gen2 interface enables data streaming to PC memory at a rate of more than 3 Gbytes/s. Each input channel of the M4i.445x-x8 has its own ADC and preamplifier. The card offers software control of its six input ranges from ±200 mV up to ±10 V, as well as 50-O or 1-MO input impedance, and AC or DC coupling. Acquisition modes include single-shot, streaming (FIFO), segmented, gated, or the combination of segmented acquisition of fast signals in parallel with slow, continuous data recording (ABA mode).
An optional star-hub module enables up to eight M4i cards to operate synchronously in one system. The star-hub can combine all of the trigger sources of all connected cards, allowing the use of any trigger source as the starting event for the entire system.
A datasheet for the M4i.445x-x8 was not available at the time of this announcement.
