The Tektronix PB200 is particularly suited to packet-based systems. It's ideal for component or sub-system development testing of TDMA, B-ISDN, FITL, ATM, Satellite modems and similar communications protocols.
The ability to generate a "Mixed Mode" data pattern allows flexibility in constructing many forms of test signals. Two separate programmable word memories of 16 to 256 Kbits in length allow the construction of a packet or cell that can consist of user-definable preamble, overhead and data. The Tektronix PB200 data generator has one word memory that is used to define the overhead and preamble and a second word memory to define the data. Each memory can consist of a user-defined pattern or PRBS. The Tektronix PB200 can also function as a fully featured non-packetized BERT.
For complete flexibility in signal analysis, the Tektronix PB200 allows BER analysis on all, or only part, of the received digital information. Analysis can be performed on only the overhead, only the data or both overhead and data at the user's selection.
