8810A Angle Position Indicator (API) is a rack-mount or bench-top measurement instrument featuring front panel controls and input terminals. The use of an intelligent DSP design eliminates push buttons and allows all programming to be done either via an integrated touch-screen, front panel USB optical mouse interface, or with the multipurpose increment/setup knob. Improved flexibility is provided by two fully independent inputs that can be used to read two separate input signals simultaneously, or can be combined to measure multi-speed Synchros or Resolvers.
