Reflection test (vector: impedance matching of antenna system debugging, inspection quality)
Spectrum display and field strength observation * * (test station emission performance, find the source of interference)
Output signal of a single frequency point
The recommended application
KC901S mainly for debugging radio frequency (RF) circuits, such as filters, amplifiers, splitter, synthetic circuit breaker, test input and output impedance, evaluation quality of the antenna feeder system, equipment levels of the signal amplitude detection. In most frequency bands, the field strength measurement and interference search can be carried out.
This instrument can effectively improve the work efficiency, reduce the carrying load, improve the quality of work. 901S is each electronic engineer should have a testing tool, also can be used as communication engineering, radio and TV transmitting station technical personnel standing instrument.What's the difference between KC901S and KC901H
KC901H is a favorite of the scalar network analyzer products, stereotypes in three years ago. Since three years, the majority of users and players have put forward a lot of valuable suggestions.
KC901S inherited the advantages of KC901H, made a great improvement, the vast majority of community recommendations have been actively respond. Their main difference is:
1, the appearance of the obvious difference, KC901S uses a more comfortable keyboard, while the integration of the degree of improvement, the size of the length of the KC901H reduced by nearly 3 cm.
2, the difference between the function, S11 KC901S function fully support vector test, the performance of the measurement of the reflection of a substantial increase, in addition to the low frequency signal source function (frequency as low as 3Hz).
3, the frequency range of the difference, S11 KC901S function can be effectively used to lower than the frequency of KC901H, S11 300KHz function can only work effectively to 1.5MHz.
4, the difference between the data interface, KC901H no data interface, KC901S has a USB interface and microSD memory card, you can easily access the results of the measurement.
5, the difference between the user experience, FPGA uses the KC901S to deal with high-speed data, the operation of fluency has a fundamental improvement; software uses a new generation KC platform, more easy to use.
6, longer life, KC901S in the maximum power consumption mode, the battery can be 4 hours (optional 5.5 hours), while the weight is reduced by about 200 grams.
7, built-in Barometer / altitude meter.
