The BNC Model 625A (SG-100A/Telulex) represents a major breakthrough in price/performance for signal generation and signal measurements and analysis. This versatile device allows the engineer to access a broad range of operating modes such as arbitrary waveform, pulse, word/data integration, function, VCO, AM, FM, SSB, FSK, and burst.

The BNC 625A is much more than a a signal generator: Never before has so much versatility, capability, and performance been packed into a single-low cost instrument. Its architecture is based on the latest advances in DSP and DDS technology which not only ensures calibrated and drift free performance, but also gives the engineer signal measurement and analysis functions such as voltage/power measurement and DTMF detection.

The BNC 625A delivers clean, fully synthesized, DC to 21.5 MHz modulated or unmodulated waveforms with ) 0.01 Hz frequency resolution and 1mV and 0.1 dBm amplitude resolution. User friendly features include a large, easy-to read LCD display which allows the user to see all modulation parameters simultaneously. A full numeric keypad and encoder provides direct editing of each parameter, without confusing sub-menus.

Areas of application include: medicine, education, communications, photonics, circuit design, power systems, and consumer electronics. 

The Arbitrary Waveform Generator allows you to design custom waveforms on your personal computer and download them to the BNC 625A which generates them in real-time. Arbitrary Waveforms may either be designed with a graphical Windows-based design tool or be generated point-by-point in a variety of data formats from your own application software. A data generator program, example waveforms, and a downloading utility are included in this option.

The Model 625A generates every data point independent of repetition rate. Normally ARB's simply replace the sinewave lookup table used in the DDS system with arbitrary waveform datapoints. With this method waveform points are actually skipped as the rest as the rep rate is increased. Our unique design ensures you maintain the characteristics of your wave form.

The TTL/CMOS SYNC output can be independently controlled which lets you create a pattern of logic pulses along with your analog waveform. This output swings 0V to +5V and can be directly drive digital logic. It is useful for designing arbitrary digital waveforms or generating a triggering or synchronizing pulse along with the analog waveform.

The BNC 625A will receive and parse waveform data in a multitude of formats. No confusing protocols or headers are required, and the data may be separated by any non digit character (carriage returns, commas, tabs, spaces, etc.), which makes it easy to download data from a variety of application programs, spreadsheets, and sampling oscilloscopes.

The function generator offers a set of pre-stored waveforms which are generated using the Arbitrary Waveform hardware. The user may quickly select from many stored waveforms, and may also specify a repetition rate to 2 MHz. All functions may be generated on a continuous or triggered basis. A high going synchronizing pulse is a given on the SYNC Output at the start of each waveform.
