Tektronix packetBERT PB200 Bit Error Rate Test Set
Packet Generator and Error Detector
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.
The Tektronix PB200 provides several unique features and
capabilities that are not found on other BERT products in this class. The
receiver has a clock/data deskew range of 32 ns and the ability to
measure propagation delay. Along with the Auto Search setup capability,
the receiver can automatically measure "eye-width" at
user-selectable BERs and extrapolate BER from data accumulated over much
shorter elapsed times than normally required. The transmitter can also
generate a gapped clock.
