ARB Connector
Note:
DAQArb 5411 User Manual
The ARB connector provides the waveform output. The maximum
output levels on this connector depend on the type of load termination.
If the output of a DAQArb 5411 terminates into a 50
levels are ±5 V, as shown in Figure 3-2. If the output of DAQArb 5411
terminates into a high impedance load (HiZ), the output levels are
±10 V. If the output terminates into any other load, the levels are:
where V
is the maximum output voltage level, R
out
impedance in ohms, and R
DAQArb 5411. By default, R
to 75
.
Software will set the voltage output levels based on a 50
For more information on waveform generation and analog output
operation, refer to Chapter 4, Arb Operation. For specifications on the
waveform output signal, see Appendix A, Specifications.
