MEASALL Distributor LY.GROUP.CHINA KC901S+ KC-901S+ Handheld Vector Network Analyzer Antenna RF

Spectrum Field Multi-meter SWR Standing Wave Testing 4GHZ VNA

901S+ is an upgraded version of 901S, the frequencies is up to 4GHZ.

KC901S+ is a universal vector antenna analyzer. It supports the analysis of single port vector network analysis and dual port scalar network analysis, meanwhile expanding the spectrum, field strength and signal generator convenient function. KC901S+ has professional practicality, and includes the battery which supports 5 hours large work load, the volume is just 1 dm³, weight is only 1 kg, bring a new experience for the user.

Main Functions

Transmission measurement (Filter adjustments, measuring amplifiers, verifying
directivity of antennas)

Reflection measurement (Impedance matching network adjustment, antenna
feeding system quality evaluation)

RF source plus an extra audio signal source

Spectrum display and field strength observation (potentially used for inspecting
a radio station’s emission performance, or for searching for the interference sources)

Recommended Applications

The KC901S+ is mainly used for adjusting various RF circuits, such as filters, amplifiers, splitters, combiners; testing input/output impedance, evaluating antenna feeding system and detecting equipment’s signal amplitudes at all levels. It can also do field strength measurement, which is useful for checking the correct operation of low powered devices with integrated antennas and when searching for interference sources etc.

◆The difference between 901S+ and 901S

901S+ is the upgraded product of 901S

901S+ adopts all digital intermediate frequency technology

901S+ the trace noise has improved more observably than 901

The electric bridge structure of 901S is improved, its nonlinear effect is smaller than 901S, and the accuracy of impedance test is improved

Based on the improvements of the electric bridge, the 901S+ can support low to 9KHz of S11 measurements, and the directionality is still good at this time

The spectrum function of 901S+ shares a port with the S11 function, and the port usage in the transmission test is the opposite of 901S

The S21 function of 901S+ is also vector, and the introduction of phase can provide more intuitive trend judgment

The frequency range of 901S+ is 9KHz – 4.1GHz.

901S+ analysis bandwidth (RBW) has four choices, respectively are 1KHz, 3KHz, 10KHz, 30KHz, spectrum function is stronger than 901S

◆Technical indicators (for reference only)

Note1:Unless otherwise specified, all indicators are measured in the medium speed mode, 10KHz RBW, 0 output attenuation, temperature 25 ℃, and through the user calibration. A few accidental or abnormal data permanent period may exceed the range of technical parameters table.

Note2:When the battery is powered, the range depends on the temperature characteristics of the battery. It exceeds 0… 45℃ should be re calibrated when the equipment is preheated and stable. Especially within the range of -40~-20℃ , should be preheated for at least 5 minutes (and need to keep running). Due to heating of the equipment itself, the shell temperature may be 20℃ higher than the ambient temperature. In more than 45℃ environment, should avoid scalding. We must remove the battery when the environment temperature is closed to 65℃. Otherwise, the battery temperature may exceed 85 ℃ and cause danger.

Note3: Restricted to usage state only. Moisture storage measures must be adopted for long-term storage at a moisture level greater than 80%
