General description of the
used BK PRECISION 4014B
for sale.
The B&K Precision 4014B is a 12 MHz DDS (direct digital synthesis) function generator that generates stable and precise sine, square, and triangle waveforms. It provides variable output voltages from 0 to 10 Vpp into 50 ohms (up to 20 Vpp into open circuit), linear and logarithmic sweep, AM/FM modulation, built-in counter, and a continuously variable DC offset that allows the output to be injected directly into circuits at the correct bias level. Separate output amplitude and DC offset amplifiers let you set a large DC offset (e.g. ± 4.99 V ) with a small amplitude output signal (e.g. 10 mV). Specifications. Frequency Range: 0.01 Hz to 12 MHz (Sine, Square), 0.01 Hz to 1 MHz (Triangle). Resolution: 6 digits(square wave) or 10 mHz. Accuracy: 0.01% ± 0.006 Hz. Amplitude Range: 10 mVpp to 10 Vpp (into 50 ohms), 20 mVpp to 20 Vpp (open circuit). Amplitude Resolution: 3 digits (1,000 counts). Amplitude Accuracy: ± 2% ± 20 mV of programmed output from 1.01 V – 10 V. Flatness: ± 0.5 dB to 1 MHz, ± 1 dB to 12 MHz. Harmonic Distortion (for sine wave at 5 Vp-p into 50 ohms): < -60 dBc (0 – 1 MHz), <-50 dBc (1 MHz – 5 MHz), <-45 dBc (5 MHz – 12 MHz). Square Rise/Fall Time: <= 20 ns (10% to 90% at full amplitude into 50 ohms). Duty Cycle Square: 20% - 80% to 2 MHz. Duty Cycle Triangle: 1% - 99% in 1% steps, up to 200 kHz. Operating Modes: Continuous, Triggered, Gate, Burst, Trigger Source. Amplitude Modulation Internal: 0.1 Hz – 20 kHz sine only. Frequency Modulation Internal: 0.1 Hz – 20 kHz sine only. Counter Range: 50 Hz to 25 MHz. Counter Resolution: Auto ranging, up to 8 digits. Counter Accuracy ± 0.02% ± 2 digits. Memory Storage: 10 instrument settings.
