APPH Phase Noise Analyzer – from 1 MHz to 7 / 26 / 40 GHz
9 kHz to 12, 20 or 26.5 GHz Signal Generators

The APSINXXG is an analog signal generator (analog signal source) series covering RF and microwave frequency ranges from 9 kHz to 12, 20 and 26.5 GHz. A combination of characteristics such as good signal purity, low phase noise and fast switching speed, along with their very compact size, low weight and low power consumption makes the instruments very well usable in labs, production halls and outdoor fields.

The APPH is a fully contained signal source analyzer with models up to 7, 26 and 40 GHz. It offers an indispensable set of measurement functions for evaluating signal sources ranging from VHF to microwave frequencies but also active and passive non self oscillating devices like amplifers, or frequency dividers. A mixed-signal system architecture with an FPGA cross correlation engine enables very fast signal processing and ultra-low phase noise sensitvity.

Measurements can be performed with the provided desktop software or with individual scripts using the remote SCPI interface for automated testing.

Built-in programmable power supplies and low noise tuning voltages make the unit extremely flexible and easy to use.

The full set of measurement capabilities includes:

  • absolute phase noise measurement of continuous wave and pulse modulated signals to characterize oscillators, synthesizers, signal generators and other self oscillating setups
  • residual phase noise measurement of continuous wave and pulse modulated signals, used to characterize amplifiers, up/down converters, mixers, dividers and other non self oscillating components
  • amplitude noise measurement of continuous wave signals
  • time stability measurement to characterize Allan deviation, derived from phase noise or from long term frequency measurements up to several days
  • transient analysis to measure signal transients or modulations with a resolution down to 16ns
  • fully automated oscillator characterization of voltage controlled oscillators (VCO), including the parameters frequency, power, current consumption, pushing and phase noise
  • monitoring spectrum of a single carrier signal
The APPH is suitable for many applications:

  • phase and amplitude noise measurement of signal sources in labs
  • evaluating pulsed signals and amplifier stages
  • automated testing in production lines
  • analyzing frequency and power transients, modulations, and long term behaviour of signals
The APPH is an all in one compact mesaurement system that offers a wide range of capabilities with measurements down to -190 dBc/Hz in an offset range from 0.01 Hz to 100 MHz.
By providing internal and external reference options, the flexibility and dynamic range of the system is increased. Internal references offer a fast measurement setup and quick measurements, while external references can improve the noise floor performance of the system.
Programmable low noise power supplies and a bias tune voltage port can be used to supply the DUT without the use of external power supplies.
The APPH can be controlled with the included desktop application that offers all measurement modes. Alternatively, the measurement instrument can also be controlled via SCPI interface over ethernet, USB or GPIB.
