Title:
SERVO SIGNAL WRITING DEVICE AND SERVO SIGNAL DELAY QUANTITY AUTOMATIC MEASURING INSTRUMENT
Document Type and Number:
Japanese Patent JPH03209680
Kind Code:
A
Abstract:
PURPOSE:To attain the setting of an arbitrary delay quantity by adjusting the delay quantity more than the interval of the bit number of a parallel-serial converting circuit by the microprogram of a microprogram sequence processor. CONSTITUTION:Parallel data outputted from a microprogram sequence processor 4 are converted into time series serial data by a parallel-serial converting circuit 2. The time series serial data pass through a delay circuit 1, are delayed by a fixed delay quantity and become a writing signal. The setting of the delay quantity in the delay circuit 1 is set in a range smaller than a reference clock 1, the delay quantity which is more than the reference clock 1 and is smaller than the bit number of the parallel-serial converting circuit 2 is adjusted by a handshake circuit 3 and the delay quantity more than the bit number of the parallel-serial converting circuit 2 is adjusted by the microprogram of a microprogram sequence processor 4.
