30/60 MHz DDS AWGs/signal generators with 14 bit resolution

New Products |
Instrumentation distributor Saelig (Fairport, New York) has introduced the Siglent SDG1000X Series of Function/Arbitrary Waveform Generators which output sine, square, ramp, and pulse waveforms to 60 MHz with a 14-bit sampling rate of 150 Msmaples/sec at up to ±20V.

The SDG1000X generators feature Siglent’s EasyPulse technology for low jitter and very fast rising and falling edges that are frequency-independent even at low duty cycle settings. EasyPulse 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, the company claims, unusual for a generator in this range to be able to produce square waves at frequencies as fast as its sine waves.


The two SDG1000X signal generators – the 30 MHz SDG1032X and the 60 MHz SDG1062X – improve on the specifications of their predecessor SDG1000 series. With 0 dBm output, the total harmonic distortion (THD) is less than 0.075%, with harmonics and spurious less than -40 dBc throughout the entire bandwidth. The rise/fall times can be set independently to the minimum of 16.8 nsec at any frequency and to the maximum of 22.4 sec. The adjustment step is as small as 100 psec. Pulse widths can be fine-tuned to a minimum of 32.6 nsec with adjustment steps as small as 100 psec.


Multiple modulation functions are included: 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 in. TFT-LCD display, and 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 arbitrary waveform editing software EasyWave supplied with the generator; up to 10 user waveforms can be saved in nonvolatile storage. Additionally, 46 built-in kinds of arbitrary waveforms are provided.


In a rugged 11.7 x 10.2 x 4.2 in. case with built-in prop stand, SDG1032X/SDG1062X AWGs are available now at $399/509.
