PROBLEM TO BE SOLVED: To provide a bit error insertion circuit for a PN pattern generator that can set a bit error to an optional position of a bit stream configuring a PN pattern signal. SOLUTION: The bit error insertion circuit for a PN pattern generator comprises a PN pattern generating section 1 that generates a PN pattern signal, an error insertion timing generating section 12 that generates an insertion timing of a bit error to be inserted to the PN pattern signal, an error generating section 13 that generates a bit error insertion signal to be inserted to the PN pattern signal, an error inserting position decision section 14 that decides a bit location of the bit error inserted to the PN pattern signal, and a PN pattern/PN error insertion section 3 that inserts the PN pattern signal to input data and inserts a 1-bit error to an optional position of the bit stream configuring the PN pattern signal.
