90SWG and90SWGD Slot Card Signal Waveform Generator For 90IP Instrumentation Platform
Distortion to – 120 dB Description: For use in the 90IP Instrumentation Platform, each 90SWG (analog output) slot card uses advanced DDS (Direct Digital Synthesis) technology to produce, high precision, ultra low distortion waveforms to –120dB. Available output signals include sine and square waves, dual tone, and white and pink noise. All with adjustable gain in 0.5 mV steps over a 200kHz bandwidth. Front panel mounted BNC’s offer easy access of signal and trigger/sync I/Os. Other features include; Sweep and Burst Mode (Repetitive, Triggered or Gated) operation. The 90SWGD is also available with a doublewide slot card that provides both analog or digital signal output.
Providing Real Time Analog and DSP Solutions for the following industries:
Features: • Selectable external or internal triggers for Burst and sweep modes. • SmartSlot technology for instrument setup and configuration. • Memory storage for up to 9 configurations • Sine wave spectral purity to –120 dB • Output to 10V p-p into 50 Ω. • Analog and optional digital signal output. • Hard front panel controller with remote GPIB and RS232 interfaces provided.
Industries: • Health • Space • Defense • Science and Technology • Engineering • Research and Development • ATE Applications: • Sound Measurement • Noise Testing • Audio test & measurement • Medical Research • Seismic Analysis • Vibration Analysis • Serial Digital Interface Testing • Converter Testing • IMD Testing
