Economical high-performance 30/60MHz DDS signal generator

Latest from Saelig is the Siglent SDG1000X Series of function / arbitrary waveform generators which output sine, square, ramp, and pulse waveforms to 60MHz with a 14-bit sampling rate of 150MSa/s at up to +/-20V. The SDG1000X generators feature patented EasyPulse technology for low jitter and very fast rising and falling edges that are frequency-independent even at low duty cycle settings. EasyPulse technology results in a much more versatile generator than competitive designs - the specially-designed edge generator is capable of generating square waveforms up to the full 30 or 60 MHz frequency with low jitter. It is extremely unusual for a generator in this range to be able to produce square waves at frequencies as fast as its sine waves. The two new SDG1000X signal generators - the 30MHz SDG1032X and the 60MHz SDG1062X - improve on the specifications of their successful predecessor SDG1000 series. With 0dBm output, the Total Harmonic Distortion (THD) is less than 0.075%, with harmonics and spurious less than -40dBc throughout the entire bandwidth. The rise/fall times can be set independently to the minimum of 16.8 ns at any frequency and to the maximum of 22.4 s. The adjustment step is as small as 100 ps. Pulse widths can be fine-tuned to a minimum of 32.6 ns with adjustment steps as small as 100ps. Multiple modulation functions are included in the SDG1000X series: AM, FM, PM, ASK, FSK, PWM, DSB-AM, linear/logarithmic sweep and burst. These instruments have a clear, straight-forward front-panel with a large 4.3" TFT-LCD display, and the user-friendly layout with its built-in help system simplifies their operation. USB host, USB device, and LAN (VXI-11) interfaces are provided, with GPIB available as a factory-fitted option. The SDG1000X generators can be seamlessly connected to any Siglent oscilloscope for waveform display or reproduction of measured signals. Multiple custom arbitrary waveforms can be created, configurable with the powerful arbitrary waveform editing software EasyWave supplied with the generator; up to 10 user waveforms can be saved in non-volatile storage. Additionally, 46 built-in kinds of arbitrary waveforms are provided. With these advantages, the SDG1000X generators provide users with a variety of high fidelity, low jitter test signals, meeting the ever-growing engineering requirements. Applications include research and education, IC and circuit testing, environmental and medical signal simulation. The rugged instruments measure 11.7 x 10.2 x 4.2 inches.
