    Besides, when no data pattern is delivered, the idle pattern can be delivered. Various FSK modulated waves can be output by combining with the FSK encoder which is optionally built in MG3641A/ MG3642A. In addition, this Pattern Generator can be used as a modulated signal source of the optional built-in pulse modulator.

    4.1 Delivery Mode Section 4 Detailed Description The Pattern Generator function is described in detail. 4.1 Delivery Mode The time charts of each delivery data patterns in both the Single and Continuous delivery modes are as follow: (1) In case that the free pattern Defined: 1 to 4 is used as the delivery data pattern When the Pattern Generator output is turned ON, the idle pattern is continuously delivered.
  • Page 18 Section 4 Detailed Description (2) In case that the PN9 pseudo-random pattern is used as the delivery data pattern When the Pattern Generator output is turned ON, the idle pattern is continuously delivered. When the delivery operation is performed, the PN9 pseudo-random pattern delivery starts just after the current idle pattern delivery is finished.
  • Page 19 4.1 Delivery Mode (3) In case that the PN15 pseudo-random pattern is used as the delivery data pattern When the Pattern Generator output is turned ON, the idle pattern is continuously delivered. When the delivery operation is performed, the PN15 pseudo-random pattern delivery starts just after the current idle pattern delivery is finished.
  • Page 20 Section 4 Detailed Description (4) In case that the 0101 fixed pattern is used as the delivery data pattern When the Pattern Generator output is turned ON, the idle pattern is continuously delivered. When the delivery operation is performed, the 0101 repetition pattern delivery starts just after the current idle pattern delivery is finished.

    4.2 Data Output Method 4.2 Data Output Method Data output method is described in detail. (1) 1-bit NRZ output method Data are sequentially output starting from the specified first delivery address LSB for the specified data bit length taken out from the Data 2 Output.
  • Page 22 Section 4 Detailed Description (2) 2-bit NRZ output method Data are sequentially output by 2-bit into the Data 2 Output and the Data 2 Output starting from the specified first delivery address LSB for the specified data bit length (an even number). This is used when the 4-value FSK modulation is performed in the combination with the FSK encoder.
