Features

Principal capabilities of the GXAO boards are summarized in the following list of features.

• Individual analog output channels:

• 64 channels (16 per group) for GX1642/48/49

• 32 channels (8 per group) for GX1632e

• DAC resolutions:

• 12-bit DAC for the GX1642/48

• 16-bit DAC for the GX1632e/49

• Accuracy:

• 3mV, ±1LSB for the GX1642/48

• 2mV, ±4LSB for the GX1649

• GX1632e depends upon voltage range:

• ±25V:                   ± (0.006V + 0.04% of programmed value)

• ±10V:                   ± (0.003V + 0.02% of programmed value)

• ±1V:                     ± (0.002V + 0.04% of programmed value)

• -8V to 25V:           ± (0.004V + 0.02% of programmed value)

• -25V to 8V:           ± (0.004V + 0.02% of programmed value)

• Operational Amplifier able to source/sink up to:

• 10 mA per channel for the GX1632e/42/48

• 5 mA per channel for the GX1649

·       Data update rate:

• 10 kS/s for the GX1642/48

• 1 MS/s for the GX1632e

• 10 MS/s for the GX1649

•  Each group can be programmed to one of the following output voltage ranges:

• GX1632e: ±25V, ±10V, ±1V, -8V to 25V, or -25V to 8V

• GX1648: 0-10V, ±10V, 0-5V or ±5V

• GX1642: 0-20V, ±20V, 0-10V or ±10V

• GX1649: ±15V

• Outputs are updated simultaneously or per channel (software-selectable)

• Four external group voltage inputs for each group allows for simultaneous continuous update

• External update input supports simultaneous updating of all groups

• Fast settling time of 50uSec to 0.1% of programmed value.

• 8 Channel digital I/O with input, output, and direction memories (8 Kbyte) as well as a programmable clock (GX1649 only)

• All channels are automatically set to zero volts DC after a power reset

• Output TTL pin (GX1642/48 only)

• Streaming callback support (GX1632e and GX1649-1 only)

• Upgradable firmware using in-system-program software driver
