Spectrum Analyzers Introduction
DSA1000A and DSA1000 series are the compact and lightweight spectrum
analyzer with premium performance for portable applications. Both of them adopt the all digital IF design, the benefits of Rigol's all digital IF design are:
- The ability to measure smaller signals: on the basis of this
technology,the IF filter enables smaller bandwidth settings, which greatly
reduce the displayed average noise level.
- The ability to distinguish between small signals by frequency:
using the IF filter with the smallest bandwidth setting it is possible to
make out signals with a frequency difference of only 10 Hz.
- High precision amplitude readings: this technology almost
eliminates the errors generated by filter switching, reference level
uncertainty, scale distortion, as well as errors produced in the process of
switching between logarithmic and linear display of amplitude when using a traditional analog IF design.
- Higher reliability: compared with traditional analog designs, the
digital IF greatly reduces the complexity of the hardware, the system
instability caused by channel aging, and the temperature sensitivity that can contribute to parts failure.
- High measurement speed: the use of digital IF technology improves
the bandwidth precision and selectivity of the filter, minimizing the
scanning time and improving the speed of the measurement.
