Test signals for bit error rate measurements

1.6.1

Internal test signals

Bit patterns as in the mainframe instrument:
• Transmitted
• Transmitted
1.6.2

External signal (with option 3035/90.20 only)

An external signal with bit rate 1544 kbit/s (coaxial or balanced) can be inserted into the
selected timeslot instead of the bit pattern (see Sec. 1.6.1).
The interfaces for this signal are described in Sec. 3, Page S-6.
1.6.3

Filler signals

Complete structured signals using the pseudo-random bit sequence PRBS 6 are transmitted in
