ValueTronics International, Inc. Arbitrary Waveform Generator SG-100/A

The SG-100/A is a 21.5 GHz arbitrary waveform generator from Telulex. An arbitrary waveform generator (AWG) is a type of electronic test equipment people use to generate repetitive or single-shot electrical waveforms. Single-shot waveforms require a triggering source, either internal or external, while repetitive waveforms do not. Inject the signal the waveform generator creates into a device for analysis during testing, finding problems with the device, or confirming proper operation.

An arbitrary waveform can be downloaded to the instrument over the RS-232 interface from a host computer. The instrument is claimed to have an architecture based on the latest advances in digital signal processing (DSP) and direct digital synthesis (DDS) technology. The SG-100/A is claimed to deliver clean, fully synthesized, DC to 21.5 MHz modulated or unmodulated waveforms with 0.01 Hz frequency resolution and 1 mV and 0.1 dBm amplitude resolution. A large LCD display allows all modulation parameters to be seen simultaneously and to assist in the navigation of the various modes. The front panel is equipped with a multiline LCD screen, a large rotary knob, a keypad for entering numbers and selecting functions and two BNC connectors (lower right hand corner). Of the latter the SIG Out connector is the main signal output. The SYNC Out connector is a TTL/CMOS compatible square-wave output. It is a “hardwired” version of the main output and is available in all modes. The SYNC Out swings 0 V to +5 V and is useful for driving digital circuitry. The wiring of the serial port is a standard female DB9. The SG-100/A is a DCE and connects to the computer with a “straight-through” cable. The function generator provides ramps, triangles, exponentials, random and sinewave functions in both continuous or triggered operation. The pulse generator provides adjustable amplitudes, offsets, repetition rates and duty cycle in both continuous or triggered operation.
