PLL, direct digital
The Astronics Test Systems 3100M Waveform Synthesizer Series combines
300 MS/s waveform generation performance, versatility, and compact size into a
single-slot VXIbus format.
The 3100M is a greatly improved version of a field-proven instrument ideal for
VXI test stimulus generation. It replaces one or two of the popular 3152A Precision
PLL Waveform Synthesizers, which are standard on many military and commercial
The 3100M defaults to its highest performance operational mode, but also can be set to operate as though it were a 3151A+ or 3152A for all modes including (and not limited to) PLL, PM, sequenced mode, trigger delay, and multi-module synchronization. The 3100M provides a front panel interface that is different from that of the 3152A. For legacy designs, please refer to literature for the 3151B and 3152B models for more information. Modulation Modes The 3100M allows the modulation of a
carrier waveform ranging up to 100 MHz with ten modulation types including AM, FM, PM, FSK, PSK, ASK, frequency hopping, amplitude hopping, 3D modulation (a combination of AM, FM, and PM), and
Pulse Width Modulation (PWM). Modulation sources are all internal except for PM (external or internal with 3D mode) and include sine, square, triangle, ramp, and arbitrary (in some cases). PWM is
generated using the included waveform creation software and downloaded to the instrument.
