Novatech Intros Low Cost Synthesizer
Seattle, WA — Novatech Instruments, Inc. is introducing the Model 409B/02, a four-output, two-frequency 171MHz Direct Digital Synthesizer (DDS) Table Top Signal Generator with 0.1Hz frequency resolution and ±1.5ppm accuracy.
The new instrument has two phase-synchronous sine-wave outputs up to 171MHz, with matching LVCMOS outputs, serial control, 500MHz external clock input, and on-board TCXO (temperature compensated crystal oscillator), stable to ±1.5ppm, all in a small table-top shielded instrument case.
Based on the Analog Devices AD9958, the 409B/02 synthesizer has 32-bits of frequency resolution, 10-bits of amplitude resolution, and 14-bits of phase resolution on each of its channels. The small table top case allows the 409B/02 to be integrated into test stations and other applications requiring multiple and frequency-agile outputs. When used with the external clock input, all 409B/02 units can be synchronized to a system-wide frequency standard.
The serial control with simple text commands provides non-volatile storage of all settings. Menu-driven control software (SOF8) is included. The instrument operates from a nominal +5VDC power source using the provided AC adapter, or a user-supplied +5VDC source. Up to four of the units can be mounted in an optional rack-adapter to fit 16 outputs in a single 1U space.
Other models in the 409B family include the 409B-AC, which adds external control of the frequency updates, and the 409B, which has four independent sine wave outputs.
