    Description:
    The VX4730 12-Channel D/A (DAC) Module consists of 12 independent single-ended 16-bit DACs, individually programmable from -16.3835 volts to +16.3835 volts in 0.5 millivolt steps. Monotonicity is guaranteed to 14 bits.
    Each output channel of the DAC provides a minimum of 60 milliamperes of current, with all channels driven. In addition, any individual channel may provide up to ±16.3835 V into a 40 Ohm load. The total amount of all 12 channels cannot exceed 720 mA.
    Conversion Rates: 1000 Voltage Changes / sec for all 12 channels; 3000 Votage Changes / sec for a single channel.
    Specifications:
    Function:
    12 channel, 16-bit digital-to-analog converter
    Digital-to-Analog Converter Type:
    Single-ended, bipolar, 16-bit DAC
    Output Range:
    -16.3835 to +16.3835 volts
    Type: Single-ended
    Minimum Step Size: 0.5 millivolts
    Maximum Output Impedance: < 0.1 ohm, dc
    Short Circuit Duration: Continuous
    Current:
    60 mA per channel, all channels driven, ± 16.3835 V into a resistive load of 40 ohms or greater, single channel driven. All 12 outputs collectively must not exceed 720 mA
    Conversion Rate:
    Throuhput is the maximum number of conversions per second which can be accomplished by the DAC on a continuous basis. The DAC is capable of in excess of 1000 voltage changes per second, all twelve channels, binary data, and 3000 voltage changes per second, single channel, binary data
    Note: The conversion time may also be limited by the system’s interface module.
    Setting Time: From the time the DAC value is programmed until the output has settled to within the specified percent of final value, 60 mA load
    Change of 32 V; 10 µs, 10%; 30 µs, 1%; 12 ms, 0.1%; 70 ms, 0.006%
    Change of 50 mV; 25 µs to within 1 mV of final value
    Accuracy: Guaranteed monotonic (0° to 55°C), 14 bits
    Linearity Error: < ±1 mV @ 25°C
    Gain and Offset Error: Adjustable to ± 0.5 mV with trim potentiometers
    Maximum Error with Time:
    Percent of full scale at 25°C:
    24 hrs: ±0.009%
    30 days: ±0.014%
    90 days: ±0.023%
    6 mths: ±0.036%
    1 year: ±0.040%
    Temperature Coefficient: 0.3 mV per °C
    Self Test Accuracy: 3% or less of full scale range
    Module per mainframe:
    The number of modules allowed in a mainframe depends on the amount of current drawn from each channel and the current rating of the mainframe power supply. Refer to Appendix D to calculate the number of VX4730 Modules that may be installed in a mainframe
    VXIbus Compatibility:
    Fully compatible with the VXIbus Specification for message based instruments with the Halt Switch in the ON position.
    VXI Device Type: VXI message based instrument, VXIbus revision 1.4
    VXI Protocol: Word serial
    VXI Module Size: C size, one slot wide
    Module-Specific Commands: All module-specific commands and data are sent via the VXIbus Byte-Available command. All module-specific commands are made up of ASCII characters. Module-specific data may be in either ASCII or binary format
    VMEbus Interface: Data transfer bus (DTB) slave – A16, D16 only
    Interrupt Level: Switch selectable, levels 1 (highest priority) through 7 (lowest)
    Interrupt Acknowledge: D16, lower 8 bits returned are the logical address of the module. Upper 8 bits contain the event or response code
    VXIbus Data Rate:
    Buffered mode write: 250K bytes/sec minimum binary or ASCII. Nonbuffered mode write: 60K bytes/sec minimum binary data, 15K bytes/sec ASCII Data
