Part Number(s): IAC-37001
Package: C Size VXI Card (9.2 x 13.4 x 1.2 inches)
Lead Free Information: B

The IAC-37001 is a Register Based “C” size VXI card containing separate Synchro/Resolver Angle Generation and Synchro/Resolver Angle Measurement instruments. Each instrument is totally independent from the other and can be programmed to operate in either the Synchro or Resolver mode at 11.8, 26, or 90 volts Line-to-Line over the frequency range of 360 to 5000 Hz.

The Measurement section allows selection of 20 or 16 Bit Binary resolution. The Generation section has a resolution of 16 Bits with an accuracy of ±25 arc sec at no load and ±36 arc sec with a 1.5 VA Synchro or Resolver load.

A Dynamic Rotation feature for the Generator provides the user with constant angular rotation either clockwise or counter clockwise via a programmed data rate, or by means of external speed and direction signals.

The two instruments can be connected together under program control to implement full wrap-around test capability.

A software driver in “C” is available on request.
