Informatie

The TAS Gemini Warp Dual Terminal Emulator is a dual data Analyzer that is especially suited for testing and evaluating modems and modem communication links. Gemini effectively tests and evaluates the performance of analog modems, limited-distance modems (LDMs), Digital Dataphone Service (DDS) sets, ISDN terminal adaptors, data multiplexers, and more. Gemini combines the features required for thorough testing into one compact unit. By combining these features, Gemini dramatically reduces the cost and complexity of data communications equipment test arrangements. The Gemini Warp is the newest member of the Gemini family of Dual Terminal Emulators. The following subsections describe the many features of the Gemini Warp, and compare those features with earlier Gemini models. 1.1. Gemini Warp Features Two Data Analyzers In One - Gemini contains two complete data communications analyzers in one compact package. This makes it easy to perform end-to-end tests on modems, DDS sets, limited distance modems, ISDN terminals, multiplexers, and other data communications equipment. Gemini's terminal emulation, data monitor, and performance testing features operate at rates from 45 to 2.048 Mbps. Advanced Performance Tests - Gemini provides built-in performance testing capabilities, including Bit Error Rate/Throughput (BERT) tests, Block Acknowledge Delay tests, Call Connect Reliability tests, Character Echo Delay tests, Data Compression/File Transfer Performance tests, Multi-Point Polling tests, and Polling tests. High Speed BERT Testing - Gemini Warp performs BERT tests at rates up to 2.048 Mbps with internal clock generation. Other Gemini test applications operate at rates up to 256 Kbps. Built-In Call Setup - Gemini can store and execute call setup instructions for virtually any modem. Call setup data formats include asynchronous, synchronous, and HDLC protocol. Characters can be coded in ASCII or EBCDIC. Gemini can also monitor and display the data flow to and from each modem. Gemini provides complete testing capability, and eliminates the additional terminals, protocol analyzers, and switching equipment previously required for modem test setups. EIA/TIA-530-A Interfaces - Gemini Warp supports the EIA/TIA 530-A Alt A Interface as well as the RS-232 Interface at either station A or B. The EIA/TIA 530-A Interface standard is currently being implemented on many high speed modems and other data communications equipment. The Gemini Warp supports use of the same Interface at both stations, or mixed interfaces (i.e., RS-232 at station A and 530-A at station B). High Speed RS-232 Interfaces - The electrical Interface for RS-232 provides V.10 compatible signal levels and templates for higher speed operation using the standard 25-pin RS-232 connector (as per the TIA Subcommittee TR-30.2 document SP-3058, dated November, 1993). For details refer to section 8.3. This Interface is still fully compatible with other RS-232 standard implementations. NOTE: The RS-232 to V.35 adapter cables which were used with the Gemini 1022 and 1022HS models will not work with the reduced voltage levels of the Gemini Warp. The Gemini Warp’s EIA/TIA 530A interfaces may be connected directly to V.35 interfaces using an appropriate adapter cable. V.35 adapter cables may be ordered from TAS. Programmable RS-232 Interfaces - Gemini Warp supports multiple configurations of the RS-232 interfaces. To provide support for the various domestic and international standards, two pins on the standard 25 pin RS-232 Interface are programmable. Pins 21 (Signal Quality Detect or Remote Loopback) and 23 (Data Rate Select) may be configured to be output signals, or input signals. Signal Lead Timing Measurements - Gemini Warp supports timing measurements of signals at either Interface. Timing measurements may be performed in parallel with any other test without degrading the performance of that test. Timing measurements may be either continuous (self triggering), or one- shot. Measurements may be performed between signals on the same station, or between stations. Timing measurements are available at either RS-232 or 530-A interfaces on the following signals: Transmit Data Transmit Clock External Transmit Clock Clear to Send Data Terminal Ready Ring Indicator Sec. Receive Data (RS-232 only) Sec. Clear to Send (RS-232 only) Receive Data Receive Clock Request to Send Data Carrier Detect Data Set Ready Sec. Transmit Data (RS-232 only) Sec. Request to Send (RS-232 only) Sec. Data Carrier Detect (RS-232 only) Remote Control - RS-232 and IEEE-488 (GPIB) control are standard with Gemini. Remote control commands are simple and easy to use, and are the same regardless of the remote control method. This makes it easy to include Gemini in automatic modem test systems. RS-232/GPIB Command Translator - Gemini can act as the GPIB controller in an automatic test system. Commands are sent to Gemini via the RS-232 remote control port, and Gemini controls the rest of the test station via GPIB. This allows any standard PC to act as a GPIB controller without additional GPIB control hardware. Optional Interface Modules - As new Interface standards are adopted, your Gemini Warp can be upgraded with optional Interface modules from TAS. Contact your TAS sales representative for more information. Software Upgrades - The Gemini Warp Software is stored on EPROMs located inside the unit. You can easily upgrade your Software by replacing the EPROMs
