Our company DCom, Ltd. s r.o. has acquired Deepace ‘s representation for our market. Deepace was founded in 2014 and develops and manufactures innovative high frequency measuring instruments. The company’s product range includes, for example, accurate, reliable and affordable portable vector network analyzers or spectrum analyzers under the MEASALL brand. These measuring instruments are used in laboratories, development centers, universities, by professionals and amateurs interested in high frequency and microwave technology. Selected products from the company’s product portfolio will soon appear in our offer.
MEASALL KC901x handheld two-port vector network analyzers
The KC901x is a multi-purpose high-frequency measurement instrument based on a network analyzer architecture. The device is available in five variants covering the frequency range from 5 kHz to 22 GHz. The main function of the KC901x is a fully dual-port vector network analyzer (VNA). Other features include simple spectrum display, field strength measurement, RF generator, AF generator.
Five instrument models cover different frequency ranges
| KC901J | KC901K | KC901R | KC901T | KC901B | |
| Frequency range (standard) | 5kHz~2GHz | 5kHz~4GHz | 5kHz~7GHz | 5kHz~10GHz | 1GHz~22GHz |
| Frequency range (enabled settings) | 0kHz~2GHz | 0 kHz ~ 4.1 GHz | 0kHz~7GHz | 0kHz~10GHz | 10MHz~22.5GHz |
| Scope of SPAN | 1kHz~2GHz | 1kHz~4GHz | 1kHz~7GHz | 1kHz~10GHz | 1kHz~22.5GHz |
In addition to the above differences, all KC901x models released have the same basic features.
The KC901x has a frequency resolution of 1 Hz, a level resolution of 0.001 dB and a phase resolution of 0.1°. The receiver is designed without tunable parts and has good linearity over the entire dynamic range.
The instrument is designed to be portable with minimal size and weight. This makes it very suitable for field experiments or measurements at the site of radio communication technology installation. Thanks to the built-in lithium battery and easy operation, it can withstand a full day of intensive measurements. Charging via USB-C interface is also a great advantage.
The free KCSDI software makes it easy to extend the measurement capabilities in the lab and measure remotely via an Ethernet connection.
KC901 Portable Vector Network Analyzer Main Features
S-parameter test
Low frequency and high frequency signal generator
Spectrum and field strength display
Recommended applications
The KC901x is primarily used for tuning various RF circuits such as filters, amplifiers, splitters, combiners, input and output impedance testing, evaluating the quality of antenna systems, and detecting signal amplitude at all levels of equipment. In some frequency bands, field strength measurements, interference searches and other work can also be performed.
The KC901x is a good tool for learning RF techniques and knowledge. In the professional field, it can be used in communication technology, antenna manufacturing, daily maintenance of radio communication equipment and R&D of RF circuits, which can effectively increase the operation efficiency, reduce the transmission load and improve the quality of work.
Technical parameters
The technical specifications of the KC901x are essentially the same, with slightly different power levels for different models. This table is for guidance only when making a selection, referring to the specifications listed in the product data sheet.
