Eight individual digital-to-analog converters are controlled by an on-board rate generator capable of speeds up to 660kHz. Output data is stored in 16k words of resident RAM, eliminating the need to continually write to the board and reducing VMEbus bandwidth.
The memory can be allocated to different channels or can be organised in a swinging buffer arrangement allowing operation in a continuous output mode. All outputs power up to zero volts and a watchdog timer is provided with time intervals selectable between 1 second and 5 minutes. With the watchdog enabled, the outputs are set to zero volts, if the outputs are not updated within the set time. Jumper selectable output reconstruction filters smooth the effects of quantisation.
The SVME-E2106 may be used as a waveform generator, storing up to eight digitized waveforms in on-board RAM. These waveforms can be continually output without CPU intervention until halted.
Features:
- Output short circuit protection
- Outputs set to 0V on power-up and after watchdog timer timeout
- Enable/disable outputs via control register
