Measurement Computing Data Acquisition Systems rev.10.4 - Manual (Page 10)

Waveform Output from Disk: Uses dynamic waveform output to continuously update
outputs from a file. The file is on a PC, which contains waveform output values, as defined by
the user.
Streamed Digital Pattern Output: This output can be via P3 pins, BNC connectors, or SCSI
III, depending on the device. The feature allows streaming continuous digital data to the
device’s 16-bit P3 digital port [or to designated BNC connectors, if applicable]. Data can be
streamed from either PC memory or from a file. The rate at which streamed output is updated
is dictated by the current DAC waveform output clock source. Digital data streaming can be
performed by itself or in concert with analog waveform output generation.
Become familiar with your system components prior to writing a
program. Know the capabilities of each device.
TIP: Prior to writing a program, review the product specifications [found
in your device hardware manual]. The specifications often make it
obvious as to which API Commands could not possibly apply. In
addition, the programmer needs to be aware of specification limits when
entering values.
