Signal Generator Simple Spectrum Analyzer Network Analyzer radio frequency SWR standing wave tester KC901V 

The KC901V is a versatile RF multimeter whose main function is the single port vector network analyzer (VNA, S11). It supports vector transmission test (S21 scalar and simple vector), simple spectrum analyzer, field strength meter, RF signal source, Audio signal source and other functions. KC901V has a professional practicality, and includes support for 4 hours of continuous work, including the battery, the volume of only 1 cbm, weighs only 1 kg, to bring users a new free experience.


 Main functions

Transmission test (scalar: debug filter, amplifier, check antenna directivity, vector: basic phase change trend)

Reflectance Test (Vector: Debug impedance matching, check the quality of the antenna feed system)

Spectrum display and field strength observation *** (test station radio performance, find the source of interference)

The signal of a certain frequency point is output separately


Recommended Applications

KC901V is mainly used for detecting and debugging RF circuit and antenna feeder system. In most frequency bands, can also be field strength measurement, interference search and so on.

This instrument is lightweight and powerful, able to previously through a large laboratory equipment to complete the measurement work easily transferred to the scene. 901V is an electronic engineer worthy of the test tools, but also as a professional communications engineering, radio and television launch pad technical staff standing equipment.

Note 1: Unless otherwise noted, the specifications are measured at medium speed mode with an analysis bandwidth (RBW) of 10 kHz, an output attenuation of 0, a temperature of 25 ° C and a user calibration. A small number of accidental or permanent abnormal data segments may be outside the scope of the specification.

Note 2: The battery temperature range depends on the battery temperature characteristics. In the range of more than 0 ... 45 ℃, the device should be re-calibrated after the preheat stability. Especially in the -40 ... -20 ℃ range, should be at least 5 minutes of preheating (and the need to keep running). Due to the heat of the device itself, the shell temperature may be higher than the ambient temperature of 20 ℃, more than 45 ℃ in the environment, should avoid burns. When used in an environment close to 65 ° C, the battery must be removed, otherwise the battery temperature may exceed 85 ° C and cause danger.

Note 3: Use only. In the humidity above 80% of the local long-term storage, must be moisture-proof measures.
