Table 1. Channel, Speed, and Resolution Specifications Overview Current Output Channels (NI 6704 only) NI 670x devices are software-timed voltage and current output devices for PCI and PXI. With NI 6704 devices, you get 16 voltage outputs and 16 current outputs that you can use at the same time independently, as well as eight digital I/O (DIO) lines. You can independently set each output from ±10 V or 0 to 20 mA. The NI 6703 delivers 16 voltage outputs in addition to eight DIO lines. All 16 current outputs are identical. You can set each channel to source current from 0 to 20 mA – it does not sink current. The channels source current without requiring an external excitation source. Each output is accurate to ±2 µA. Hardware Voltage Output Channels All 16 voltage outputs on the NI 6703 and NI 6704 are identical. You can set each channel for a bipolar voltage output of ±10 V. Each output is accurate to ±1 mV. I/O Connector The analog outputs are available at a 68-pin SCSI II shielded connector. VCH<0..15> are the voltage output channels. ICH<16..31> are the current output channels. Each channel is referenced to a ground line, AO GND<0...31>, which is shared between a voltage and current channel. A fused 5 VDC power signal from the PCI or PXI bus is available at the I/O connector as well.
