SG03-840002 Miniature RF Signal Generator
The ETL Systems SG03-840002 is a miniature RF signal generator covering 25–3000 MHz with 1 Hz frequency resolution. Output power is adjustable from −17 to +13 dBm in 0.5 dB steps, supporting continuous output, frequency sweeps and externally triggered RF on/off operation.
USB, Ethernet and RS-232 interfaces support PC-based control through the supplied graphical software or ASCII commands. The software allows adjustment of frequency, output level, reference selection, sweep configuration, power-on defaults and network settings, and supports control of multiple units.
The generator includes an internal 100 MHz reference and accepts a software-selectable 10 MHz or 100 MHz external reference. Its SMA female reference port automatically detects and switches between reference input and output operation. Control software, a USB-to-mini-USB cable and an AC power supply adaptor are included.

Configuration and Ordering Notes
This listing covers the SG03-840002 miniature signal generator with the included items identified above. The optional OPT06 mounting bracket pair and other accessories are supplied only when included in the quotation.
The detailed V2.1 specification table states internal reference stability of ±20 ppm over temperature and ageing of ±1 ppm per year, with ±3 ppm in the first year. The overview's ±1 ppm reference callout should not be interpreted as the temperature stability rating.
Specify external reference requirements, control interface and any mounting accessories when requesting a quotation.
