The FIREBERD 1500 is designed to aid in troubleshooting and evaluating digital communication systems. It generates a variety of test patterns which are transmitted through the system. The receiver counts discrepancies between what is received and what was transmitted. The FIREBERD 1500 has an independent transmitter and receiver which can be used to either provide loop-around or end-to-end testing capability. The FIREBERD 1500 measures bit error rate, bit errors, block errors, error seconds and total seconds of test at any data rate between 300 bps and 10 Mbps. Additional measurement features include automatic polarity detection, automatic synchronization and the ability to count through error bursts. These capabilities will be described later in more detail. All data and clock signals interface with the FIREBERD 1500 via rugged..plug-in modules which insert through the rear panel. Each..module meets...- a different standard interface specification and includes the standard connector. Full self-test capability is provided. This feature allows the entire FIREBERD 1500 and the interface module in use to be tested without any additional test equipment. The FIREBERD 1500 provides an RS-232 printer interface and printer controls as standard equipment. An IEEE 488 printer interface is also available. This interface can be used to output directly to a 488-compatible printer. Alternatively, this interface allows the FIREBERD 1500 to act as an “addressable talker” in a 488 bus configuration. A six digit display and a variety of front panel indicators provide measurement results and the status of the system under test. Rear panel test points.allow data from the systemundertest..tobe furtheranalyzed with an oscilloscope. • Test Patterns: Pseudorandom sequences of length 63, 511, 2047, 215-1# and 220-1, Constant mark, constant space..and alternating mark-space • Bit Rate: 300 Hz to 10 MHz e Internal Standard Clock Frequencies: 1.2, 2.4, 4.8, 9.6, 19.2, and 56 kHz 9 Internal Optional Clock Frequencies (up to 3): 300 Hz to 10 MHz • Internal Clock Accuracy (std. or opt. clocks): 50 PPM accuracy 0 to 50°C (optional : 1 ppm accuracy at 25°C and 5 ppm stability from 0 to 40" C) Block Length: TD^,.10^, or 10^ bits BER Test Length: 105, 106, 107, 108, 109 or 1010 bits • 8ER Range: 1 to 10 errors/bit -.3 • Error Insertion: Single error or constant 10 error rate • LED Indicators: Sync, Sync Lost, Receive Data Invert, Receive Clock Activity, Transmit Clock Activity, Receive Data Mark, Receive- Data Space, DSR (DM), CTS (CS), RLSD (RR) • Input/Output Signals via Interface Modules: TX Clock Out, TX Clock In, TX Data, RCV Data, RCV Clock, DSR (DM), CTS (CS), RLSD (RR), RTS (RS), DTR (TR) • Signals.at..Rear.................................................
