Description

4141 series signal source analyzer adopts dual-channel cross-correlation technology, with excellent phase noise, amplitude noise and baseband noise measurement capabilities, while with transient measurement, spectrum monitoring, frequency power measurement and other measurement functions, with wide frequency coverage, large dynamic range, high sensitivity, high measurement accuracy. A single device can complete the comprehensive performance evaluation of the signal source. It can be widely used in the test of multiple parameters of signal source in electronic equipment, and is an important instrument and equipment in the process of scientific research, production and measurement.

The 4141 series signal source analyzer has rich measuring functions, which can measure the phase noise, amplitude noise, frequency power of the signal, and carry out spectrum monitoring of the signal.
The 4141 series signal source analyzer supports two high-speed dead-free frequency measurement modes to measure signals such as frequency hopping, agile conversion and linear frequency modulation. The wideband mode can measure the change of frequency relative to time. Narrow-band mode can measure the power relative to time, frequency relative to time, phase relative to time.
The 4141 series signal source analyzer uses a high-precision power meter probe to measure the input signal power, and uses a 35dB programmed attenuator to adjust the input signal power, and the power range is up to plus or minus 20dBm; It can meet the test requirements of large dynamic range.
The 4141 series signal source analyzer can output two ultra-low noise DC power supplies, one as a power supply and one as a tuning power supply, which can be used to measure the characteristics of VCO devices. Support voltage scan output, can describe the VCO device output frequency with the tuning voltage change curve; The variation of output signal power with tuning voltage.
With the continuous optimization of the design, the power supply noise has attracted more and more attention, and the power supply noise will be modulated to the output signal, resulting in unnecessary stray and crossmodulation signals. The 4141 series signal source analyzer can calmly characterize the noise situation from 1Hz to 100MHz of each power supply of the instrument, which helps us make correct judgments on circuit optimization.
The 4141 series signal source analyzer provides a variety of external interfaces such as LAN, GPIB, USB, etc., to facilitate users to achieve remote control and expand peripherals.
Widescreen color LCD is standard with 8.4-inch, 170-degree viewing Angle, high brightness and high resolution LCD. Users can also connect to a large display via VGA.
