Benchtop Performance at a Fraction of the Cost
The SG-9000 is built on Analog Devices’ high-performance, AD9910 14-bit direct digital synthesizer; Microchip’s ATmega-2560 microcontroller; Abracon TCXOs; Mini-Circuits’ digital-step RF attenuators and RF switches. Combined, these technologies deliver comparable performance to expensive benchtop signal generators at a fraction of the cost.
Windows UI and Open Source Software
Operation is simple and intuitive using the SG-9000 Windows remote control application or chose SCPI1 command interface in the LabView environment.
Open source ATmega2560 MCU software developed in the Arduino integrated development environment (IDE) allows you to customize code for your specific test application.
Compact, Rugged, and Portable
The SG-9000 is packaged in a compact extruded aluminum enclosure, black anodized finished and laser etched lettering for exceptional appearance and durability. The small form-factor conserves valuable lab bench space while the light-weight ruggedized packaging makes it ideal for field service tasks.
Front Panel Key Operating Features
- RF OFF LED illuminates yellow when the RF output is off
- REV PWR (reverse RF power) LED illuminates red when an external RF power source greater than +20 dBm typical is inadvertently applied to the RF output connector. The RF output remains off until manually reset
- RF OUTPUT push-button switch, duplicates the Windows RF on/off output control function also resets the reverse power latched off state
- Organic LED (OLED) displays the instruments current operating status
- EXT Sync Signal RF Out TTL-high when the RF output is enabled, TTL-low when the RF output is disabled―an excellent aid in evaluating radio receiver AGC attack/release time characteristics.
- EXT Sync Signal Sweep Start TTL-high 15 µs pulse generated at the start of each sweep cycle―perfect for oscilloscope sweep triggering during bode-plot evaluation of filters and networks.
Rear Panel Key Connectivity Features
- DC PWR IN accepts 10 to 33 VDC, reverse polarity/transient protected and galvanically isolated from the input power source
- PROGRAMMING PORT (RX0/TX0) supports Arduino IDE firmware upgrade
- REMOTE CONTROL (RX1TX1) USB-B port, supports the SG-9000 Windows-10 remote control application
- RX0/TX0 & RX1/TX1 Red/green LEDs indicate serial USB Arduino IDE and remote control communications activity
- EXT REF IN, external 40 MHz reference input, -10 dBm typical. Suitable for use with a GPSDO frequency reference source.
- Case Electrical Ground, Banna Jack, 4.5 mm
