Generate accurate multitone and noise power ratio (NPR) signals

N7621B Signal Studio for multitone distortion simplifies the creation of multitone and noise power ratio (NPR) signals for testing of components and receivers for communications systems. Generate up to 4096 discrete CW tones with multitone signals over 80 dBc third-order intermodulation distortion (IMD) or NPR test stimulus with over 60 dc notch depth.

Optimized multitone distortion and NPR signals for narrowband components

External frequency translation and gain/loss place the signal at the user's reference plan. Corrected waveforms and application settings are easily saved and reused, reducing complexity and cost of test. Advanced calibration routines provide very precise multitone signals that are accurate in both amplitude and phase. Combining the software with a PSG and a wideband ARB allows for the creation of NPR or multitone signals that are significantly wider than 2 GHz of bandwidth for carrier frequencies up to 44 GHz.

Signal Studio supports multiple platforms

  • The EXG has industry-leading performance in manufacturing or component test applications
  • The MXG vector signal generators provide lower phase noise, excellent level accuracy, and digital I/Q inputs and outputs making it better suited for early receiver test
  • The PSG vector signal generators provide excellent phase noise, digital I/Q inputs for very wideband applications, and high frequency coverage to 44 GHz
  • The Keysight arbitrary waveform generators supply the widest bandwidth with excellent dynamic range

Signal creation

  • Distortion free two-tone and multitone test stimulus generation
  • Configure a noise power ratio (NPR) test stimulus with up to 80 MHz noise bandwidth, >60 dBc notch depth, and +/- .5 db noise flatness
  • Automatically apply pre-distortion using a spectrum analyzer to enhance signal quality and minimize test uncertainty

Hardware platform control and additive impairments

  • Compatible instruments: ESG, PSG and MXG signal generators and M9330A, N603XA, N824XA, and M8190A arbitrary waveform generators
  • Control frequency, amplitude, ALC, markers, triggers, and more
  • Set individual instrument parameters from the software GUI or API

Automation and communication interface

  • Automate test with COM or .NET API
  • API-controlled waveform sequencing for smooth transition between signals
  • LAN and GPIB
