Limits of acceptable error of the sweep time is ± 30% , the accelerated mode, the sweep time is in the range of 20c to 500c decreases by at least 10 times. Detection rate in accelerated analysis of adjustable three lower divisions of the graticule indicator;
In tracking mode, the spectrum analyzer provides automatic adjustment to the maximum response of the selected spectral component at tuning slope response to the level of 0.1 within the set span and bandwidths from 3 Hz to 300 Hz;
S4-74 provides the mode-related functions;
The device has the ability to display two channels of spectrogram and the possibility of storing a single channel;
When you overload the input S4-74 included overload indication;

In the technical documentation for each device or product, information is provided on the list and amount of precious metals content. The documentation gives the exact weight in grams of precious metals: Au gold, palladium Pd, platinum Pt, silver Ag, tantalum Ta and other platinum group metals (PGM) per unit item. These precious metals are found in nature in very limited quantities and therefore have such a high price.

On our website you can familiarize yourself with the technical characteristics of devices and obtain information on the content of precious metals in devices and radio components manufactured in the USSR. We draw your attention to the fact that often the actual content of precious metals differs by 10-25% from the reference one in a smaller direction! The price of precious metals will depend on their value and mass in grams.

We also have an extensive database of technical and metrological documents: technical specifications (TS), the terms of reference (TOR), GOST (DSTU), the industry standard (OST) test procedure, the method of certification, verification scheme for more than 3,500 types of measuring equipment from the manufacturer this equipment. From the site you can download all the necessary software (the software driver) is required for the product purchased.

Our company carries out repairs and maintenance of measuring equipment in more than 75 different factories of the former Soviet Union and CIS.

We also have a library of legal documents that are related to our field of activity: the law, code, ordinance, decree, temporary position.
