Model 1450B Rubidium Standard with Optional 30MHz DDS Signal Generator. The 1450B (Data Sheet) outputs can be configured as sine waves or square waves and can provide frequencies of 10MHz, 1MHz, 100kHz, 1pps or an optional signal generator output. The signal generator uses direct digital synthesizer (DDS) technology and is programmable from 100Hz to 30MHz. The 1450B also includes a 1pps input that can be used to discipline and automatically calibrate the 1450B. The 1pps input signal is typically obtained from an external device like a GPS frequency receiver/antenna. The Novatech GPS1 Smart Antenna with 1pps output is available as an accessory to provide a complete turnkey solution.

Model 1940A 4-Channel 400MHz DDS Signal Generator. The 1940A (Data Sheet) uses direct digital synthesizer (DDS) technology to generate up to four different sine wave outputs simultaneously. The output frequencies are programmable from 200kHz to 400MHz in 1Hz steps and can be locked to an external frequency standard or system clock. The 1940A includes attenuators to provide 10, 20, 30, 40, 50, or 60dB attenuation. The 1940A provides front panel display and controls for setting the frequency and attenuation. It also provides an RS232 interface to allow remote programming from a computer. The SOF8_1940 (Manual) windows software is included.

Model 2910B/RACK 4-Channel 30MHz DDS Signal Generator. The 2910B/RACK (Data Sheet) generates sine, TTL or squarewave differential outputs from 100Hz to 30MHz with 1µHz resolution. The 2910B/RACK provides front panel display and controls for setting the frequency. It also provides an RS232 interface to allow remote programming from a computer. The 2910B/RACK signal generator outputs are lockable to an external frequency standard or system clock.
