BK PRECISION 4040B 20 MHz DDS Sweep Function Generators

The B&K Precision 4040B is a 20 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 20 MHz (Sine, Square), 0.01 Hz to 2 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 20 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), <-50 dBc (12 MHz – 20 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, square, or triangle waveform. Frequency Modulation Internal: 0.1 Hz – 20 kHz sine, square, or triangle waveform. Counter Range: 50 Hz to 25 MHz. Counter Resolution: Auto ranging, up to 8 digits. Counter Accuracy ± 0.02% ± 2 digits. Memory Storage: 20 instrument settings.

Clipping is the limiting of a signal so that it never exceeds some threshold.

Line Regulation
Line regulation is the capability to maintain a constant output voltage level on the output channel of a power supply despite changes to the input voltage level.

Peak Envelope Power
Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.

RMS or root mean square is a statistical measure of the magnitude of a varying quantity
