PVR6-40
PROGRAMMABLE VOLTAGE

6 Channel 12 bit IEEE D/A converter for programming reference voltages

40 I/O line digital interface for data transfer of general purpose data signals.


A compact multifunction voltage reference and digital interface.

PROGRAMMABLE VOLTAGE

DIGITAL INTERFACE

The unit has as standard, six analogue output channels. Output voltages are selected and changed by data transmitted over the IEEE bus.
Channels can be programmed individually for any output up to full scale of 10v.
Each channel employs a separate 12 bit D/A converter to provide programmable outputs in increments of 1 part in 4096 which is equivalent to a resolution of better than 5mV.
Channels are addressed S - X and voltages are set by directly programming the voltage or by specifying the bit count to the D/A register.
As an added feature the unit has a digital I/O interface that enables an IEEE-488 controller to programme 40 I/O lines at TTL level. In output mode lines may be allocated in groups of 4 for easy transfer of hexadecimal data. In addition just one or more lines may be changed at a time enabling the unit to be used in control applications.
In input mode one or more 4 line ports may be read at a time and the data is returned as one or more hexadecimal characters.
