Claims (1)

[Scope of utility model registration request] An angle signal transmitter that transmits any synchronized angle signal to the outside, and a synchronized angle signal that converts the synchronized angle signal from the angle signal transmitter into a digital angle signal.
A digital converter, a synchro/digital converter that converts an external synchro angle signal into a digital angle signal, a hold/through circuit that switches the synchro/digital converted digital angle signal to hold or through, and a hold/through circuit. a display device that displays the digital angle of the angle signal output from the hold/through circuit, and a calculator that calculates the difference between the angle signals output from the two hold/through circuits;
A digital/analog converter that converts the calculated digital signal into an analog signal, a peak value hold circuit that detects and holds the peak value from the output of the above calculation unit, and a reset circuit that clears the held peak value each time the measurement is performed. , a display that displays the peak value obtained from the peak value hold circuit as a digital angle as transmission accuracy, and converts the synchronized angle signal from the angle signal transmitter and the outside into synchronization/digital conversion, and displays this on the display. In addition to displaying the digital angle, the hold/through circuit, arithmetic unit, and digital/analog converter output the angle error voltage, and the maximum value of the arithmetic unit output is detected and held by the peak value hold circuit. An angular transmission accuracy measuring device characterized in that the static transmission accuracy and dynamic transmission accuracy of an angular transmission system are measured by displaying the maximum value in digital angle on a display.
