The SG-100/A provides a broad range of operating modes, such as arbitrary waveform, pulse, word data integration, function, dual tone, sweep, VCO, AM, FM, SSB, FSK, and burst. 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.
