Capabilities Description
Time-Dependent Signals Simple user-defined audio sweeps and tone sequences are permitted.
The sweep feature permits sweeping frequency and amplitude separately,
or both simultaneously if necessary. The sweep test signal is a set of
discrete test frequencies, not a linear sweep of frequencies from start to
stop.
Digital Signal Generation Digital signal generation is similar to analog signal generation. This
includes the ability to generate the same signal simultaneously on the
analog and digital outputs.
In order to operate analog and digital generators from the same controlling
parameters, it is necessary for the user to supply a conversion factor
between generator voltage and full-scale digital amplitude. This conversion
factor may be entered from the user interface under System Setup
Conversion Factors.
Generator Signals Table 1–21 describes each signal that may be generated in the AM700.
Some signals cannot be generated by every generator. Please refer to the
following table for each generator signal output capability.
