BK Precision 4040B 20-MHz DDS Function Generator
Harga dapat berubah sewaktu-waktu mengikuti perkembangan kurs rupiah terhadap mata uang asing lainnya sehingga sangat mungkin terjadi adanya perbedaan harga yang berlaku dengan harga yang tertera pada website kami.
The BK Precision 4040B DDS Sweep Function Generator is a Direct Digital Synthesis (DDS) function generator which generates stable and precise sine, square, and triangle waveforms. This unit provides variable output voltages from 0 to 10 peak-to-peak voltage into 50 ohms, 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 allow the user to set a large DC offset with a small amplitude output signal. The BK Precision 4040B DDS Sweep Function Generator is designed with a dual technology architecture, combining traditional DDS technology with a low-jitter square wave generator. The unit generates a 2-point waveform to simulate the amplitude and utilize a high accuracy Phase-Locked Loop (PLL) circuit for timing. This implementation significantly minimizes jitter and improves edge stability of square waves. The improved signal integrity allows this unit to be used for simulating reliable clock signals, generating triggers, validating serial data buses. The BK Precision 4040B DDS Sweep Function Generator is well suited for education and other applications which require digital function generators with sweep and modulation capabilities.
