DESCRIPTION
The DR-11525 is a versatile multiplying digital-to-resolver converter.
The digital input represents an angle, and the output is resolver type,
sin/cos. The reference input will accept any waveform, even a saw-
tooth for CRT drive. Because the reference is DC-coupled to the out-
put, the DR-11525 can be used as: a digital-to-resolver converter
using a sinusoidal reference as an input; a digital-to-sin/cos dc con-
verter using a DC reference; a polar-to-rectangular converter using a
reference input proportional to the radius vector; or a rotating cart-
wheel sweep generator for PPI displays using a sawtooth reference.
The DR-11525 is a complete D/R converter in one hybrid module.
The DR-11525 circuit design allows for higher accuracy and reduces
the output scale factor variation so that the output can drive displays
directly. The output line-to-ground voltage can be scaled by external
resistors. The DR-11525 also includes high AC and DC common-
mode rejection at the reference input.
APPLICATIONS
Because of its high reliability, small size and low power consumption,
the hybrid DR-11525 is ideal for the most stringent and severe indus-
trial and military ground or avionics applications. All units are avail-
able with MIL-PRF-38534 processing as a standard option.
Among the many possible applications are computer-based systems
in which digital angle information is processed, such as
synchro/resolver simulators, flight trainers, flight instrumentation, fire
control systems, IR, and radar and navigation systems. In addition,
the DR-11525 is ideal for motor and robotic control test systems.
