The OMB-ADC488 Series enables high-speed, high-resolution analog voltage measurements via the IEEE bus. These converters provide functions typically associated with expensive waveform recorders and digital storage oscilloscopes.

The OMB-ADC488/16 provides 16 channels of analog input with 16-bit resolution and 100 kHz sampling rate. For maximum flexibility the input provides a variety of trigger sources including analog input level, external TTL input and IEEE bus commands. Each OMB-ADC488 is equipped as standard with 2K memory for on-board data storage. One hundred percent of the memory may also be used for storing pre-trigger data. The memory may be expanded to 256K with the OMB-MEMX2 option.

If more than 16 channels are required, up to four OMB-ADC488/16 boards may function as slaves to a single master unit. This provides up to 80 single-ended or 40 differential signals. Once the master is triggered, all slaves acquire data within 250 nsec of the time event, ensuring precise time correlation.

The OMB-ADC488/8S is an eight-channel version offering simultaneous sampling on all eight channels. The simultaneous sample/hold architecture virtually eliminates time skew and phase shift between channels.
