Warning Because 6703/6704 devices are not electrically isolated from high voltages, a load with high common-mode voltages can damage the devices. National Instruments is liable for any damages resulting from any such signal connections. Your 6703/6704 device has a bipolar voltage range of –10.1 to +10.1 V. -
Page 18: Current Output For The 6704
Warning Because 6704 devices are not electrically isolated from high voltages, a load with high common-mode voltages can damage the 6704 devices. National Instruments is liable for any damages resulting from any such signal connections. Figure 3-3 shows how to connect a current channel (ICH) as a current output. -
Page 19: Power-Up Condition
Chapter 3 Signal Connections voltage channel sharing the ground line. You can approach this problem in the following ways: – Use a shorter cable to minimize the impedance of the shared ground line. – Use separate wiring for VCH and ICH ground return to minimize common ground impedance. -
Page 20: Power-Up Condition
Under no circumstances should you connect these +5 V power pins directly to Warning ground or to any other voltage source on your 6703/6704 device or any other device. Doing so can damage your device and your computer system. National Instruments is liable for damage resulting from such a connection. -

Chapter 4 Hardware Overview Bus Interface Circuitry The bus interface circuitry monitors the PCI or PXI bus. If the bus address matches the 6703/6704 device’s address, the board is enabled and the corresponding register on the 6703/6704 is accessed. I/O Connector All user I/O is transmitted through a 68-pin connector. -
Page 23: Self-Calibration

Page 24: Table 5-1. 6703 Calibration Channel Numbers
Chapter 5 Calibration accuracy of at least 10 ppm will generally suffice, but be sure to check its specifications. Also, be sure that no other devices are connected to your 6703/6704 when you calibrate it to ensure that no ground loops can corrupt the calibration. -
Page 25: Voltage Output Calibration
To calibrate the offset, set one of the current output channels to 100 µA and measure it with a precise ammeter. Then, change the current offset channel value until the output is as close as possible to 100 µA. The current you © National Instruments Corporation PCI/PXI-6703/6704 User Manual... -
Page 26: Gain Adjustment
Chapter 5 Calibration write to the current offset channel will be close to 10 µA, and increasing it will lower the current you measure. Gain Adjustment To calibrate the gain, set the current output channel to a current near full-scale, such as 20 mA. Then, change the current gain channel value until the output that you measure is as close as possible to the current that you wrote to the output channel. -
