Obvious advantage of VXI-based modular equipment has promoted its wide
distribution. Today IEM KVARZ manufactures over 70 various-purpose modules and
base units, that enables customers to build
automated measurement systems.
The automated measurement systems ensure the solution of a number of
measurement tasks, e.g., parameter measurement and test of communication
systems, radiolocation systems, navigation systems, measurement data
collection and processing system.   
A unique automated complex of highly offline metrological service ensures
calibration test
of the entire radio and electronic equipment at five automated operating
positions. It has self-calibration test, self-diagnostics, high degree of
self-control. Besides, it has a unique software that enables a customer to
independently develop programs for testing
of operating measurement means.
  
A group time and frequency keeper (GTFK) is a system for forming the
ground reference time scale of satellite radio-navigation systems. It consists
of four CH1-75A Active
Hydrogen Standards, an automated measurement system for the keepers frequency
and phase difference, a system for forming the group frequency and time scale.
The main feature of GTFK is the use of a passive voltage summer jointly with
built-in tunable frequency synthesizers of hydrogen masers, for frequency and
phase correction of the hydrogen standards signals, that enables to maintain
continuous output signal of the reference frequency, even in case of failure
of one unit of the hydrogen standards group.

Automated
radiomeasurement complex with the frequency range up to 39.5 GHz (may be
extended up to 118 GHz) comprises a set of measurement antennas and
receiving-analyzing equipment. Provides control and high precision
measurements of electromagnetic field parameters and various radiosignal
source parameters. The complex may be used to control radiotransmission
parameters for information protection estimate and also to measure
electromagnetic compatibility parameters of a radioelectronic equipment.
