Rigol DSA1020 is a compact and lightweight portable spectrum analyzer. The use of digital IF technology guarantees reliability and premium performance to meet the most demanding RF applications.

Rigol DSA1020 Spectrum Analyzer Features

  • 8,5 inch widescreen LCD display with 800×480 resolution and fine spectral lines for displaying large data sets
  • Clear, vivid, and easy-to-use graphical interface with various options such as LAN/USB host, USB device, VGA or GPIB
  • Compact and rugged design, which makes the analyzer ideal for many portable and field applications. Spot tests are easier than ever with this small, lightweight analyzer. Despite the small size, the analyzer has a built-in 3 hour lithium battery, easy carry system, extra storage space (non-volatile memory) onboard and the ability to store data directly to a USB flash device
  • Various measurement functions:
    • Time domain power
    • Channel power
    • Adjacent-channel power
    • Occupied bandwidth
    • Carrier to noise ratio
    • Harmonic distortion
    • Intermodulation distortion
    • Frequency count
    • N dB
    • Noise marker and so on.
    Software displays waterfall curves to expand the measurement capabilities to even more applications.

  • Automatic setting and functions. Auto tune, auto range, auto scale, auto couple enable the analyzer to acquire signals and match parameters automatically, instead of the manual process used by a traditional analyzer.
    The user and factory settings under the preset function help you to quickly and easily recall previous measurement settings.
  • Digital IF design. Benefits:
    • Ability to measure smaller signals measurements. IF filter enables smaller bandwidth settings and greatly reduces the displayed average noise level
    • Ability to make out signals with frequency difference of only 10 Hz
    • High precision amplitude readings. This technology almost completely eliminates errors generated by filter switching, reference level uncertainty, and scale distortion, as well as errors produced in the process of switching between logarithmic and linear display of amplitude when using a traditional analog design
    • Higher reliability. IF technology greatly reduces the complexity of the hardware, the system instability caused by channel aging, and the temperature sensitivity, which can contribute to parts failure
    • High measurement speed. Improved bandwidth precision, filter selectivity and minimized scanning time
