Protek's DDS function generator boasts stability
-- Test & Measurement World, 7/14/2008 9:09:00 AM
Heading Protek's B8000FD series of dual-output DDS function generators is the Model B8040FD, an instrument that operates from 1 µHz to 40 MHz with harmonic distortion of less than –54 dBc for sine waves. It also delivers 40-ppm long-term stability and 1-ppm short-term stability.
In addition to sine waves, the B8040FD generates square, pulse, triangle, ramp, sine (x) x, exponential up, and exponential down waveforms, plus noise. It also provides AM, FM, PM, FSK, ASK, and PSK modulation and bursts of up to 65,535 of all internal waveforms. The frequency range is 1 µHz to 40 MHz for sine waves, up to 5 MHz for square waves, and 1 MHz for all other waveforms. The generator features a built-in 100-MHz frequency counter, RS-232 interface, and keyboard for rapid entry of waveform parameters.
The B8000FD series also offers three lower-frequency models: the B8003FD, with a frequency range of 1 µHz to 3 MHz; the B8010FD, covering 1 µHz to 10 MHz; and the B8020FD, which spans 1 µHz to 20 MHz. All units have the same features and functions as the flagship B8040FD model.
Prices start at $387 for the B8003FD, $484 for the B8010FD, $599 for the B8020FD, and $778 for the B8040FD.Protek, www.protektest.com.
