Hewlett Packard HP 4951B Protocol Analyzer w/ RS-232 C/V.24 Port – Made in USA

The 4951B Protocol Analyzer is a portable Data Communications Protocol Analyzer that is small in size, weight, and price yet combined with it’s ease of use, power, and versatility it’s excellent for use in installation and maintenance of data terminal and data communication equipment.

With the 4951B you can monitor and decode data transmissions, simulate network components, perform error tests and remotely transfer data and programs through a separate RS-232/V.24 port.

External viewing is supported via a standard RS-170 video port. Integral mass storage allows you to capture large amounts of data for future use.

General Operating Characteristics 

• Protocols: X.25, SNA, X.21, DDCMP, HDLC, SDLC (NRZI), BSC, IPARS, and character asynchronous or synchronous protocols. 
• Data Transfer Rates (bps): 50, 75, 110, 134.5, 150, 200, 300, 600, 1200, 1800, 2000, 2400, 3200, 3600, 4800, 7200, 9600, 12000, 14400, 16000, 19200, teletext 1200/75, and EXTERNAL up to 19200 full duplex for all monitoring, simulation, triggering, and BERT tests. Exceptions: asynchronous at 12000 bps; synchronous NRZI at 12000, 14400, and 16000 bps. BERT at Teletext 1200/75, 16000, 14400, and 150 bps. The HP 4951B can capture a complete buffer full of data at line speeds up to 64 kbps (bit-oriented protocols only, no triggering). 
• Data Codes: ASCII, EBCDIC, Baudot, Six Bit Transcode, IPARS, and EBCD. 
• Capture Memory: 32 Kbytes of RAM stores data characters, tim-ing, and lead status information. 
• Optional Tape Drive: 512 Kbytes. Store data, timing information, and menu configurations. 
• Lead Status: The status of five control leads are stored for each in-terface. They are RTS, CTS, DTR, DSR, and CD for RS-232C/V.24 and CS, RS, RR, TR, and DM for the RS-449 interface. 
• Character Framing: 5,6,7, or 8 information bits, plus parity. For asynchronous systems, select 1, 1.5, or 2 stop bits per character. 
• Error Checking: CRC-CCITT, CRC-16, CRC-12, CRC-6, LRC and parity. 
• Triggers: 63. Consisting of characters, errors, interface lead transi-tions or timer values. May be simultaneously active up to 19200 bits per second. 
• Timers: Five. Each timer has a maximum count of 65565 ms. Resolution 1 ms. 
• Counters: Five. Each counter may be incremented up to 9999. 
• Keyboard: Full ASCII keyboard with six softkeys and cursor con-trol. 
• Display: 12.7 cm (5 in.) diagonal with 16 lines and 32 characters per line. 
• Display Formats: DTE data over DCE data, Data and Lead State, DTE data only, DCE data only, and Frame and Packet decode.
