Frequency comparators CHK7-1011 and CHK7-1011/1 can also be used as frequency and time standards with frequency correction based on GLONASS/GPS signals as sources of highly stable signals in various frequency measuring systems. Comparators have a built-in device for processing measurement data based on a microcomputer, which provides statistical processing of the results of frequency and time measurements, and a device for displaying information based on a color TFT display. The built-in diagnostic system allows you to quickly determine the operability and condition of the main comparator devices with information output to the built-in display screen. Comparators are available in three versions and differ in composition and functions performed. Comparators have a basic set of devices (modules), including a frequency comparator, a power supply module and a device for processing and displaying information based on a microcomputer and a color TFT display. The frequency comparator CHK7-1011 has a built-in SRNS receiver and a highly stable rubidium frequency standard Ch1-1014 with the function of correcting the actual frequency value by signals from satellite radio navigation systems GLONASS or GPS. The comparator forms its own time scale with the ability to synchronize on any external time scale received by the SRNS receiver built into the device. The device has two modes for measuring the deviation of the generated time scale: from the time scale of the built-in SRNS receiver and from the external time scale. Information about the current time received from the SRNS receiver is displayed on the comparator display screen, and is also transmitted to the consumer via the RS-485 interface. All the above-mentioned features make the frequency comparator CHK7-1011 a unique measuring device in the field of frequency and time measurements. The frequency comparator CHK7-1011/1 has a highly stable rubidium frequency standard Ch1-1013 and can be used as a frequency and time standard as a source of highly stable signals in various frequency measuring systems. The frequency comparator CHK7-1011/2 does not include any additional devices. To carry out measurements with it, it is necessary to use a highly stable signal of the reference frequency from an external RF or hydrogen frequency standard. For the convenience of users, apart from the keypad, they can also exercise control of the functions of the devices with a mouse-type manipulator included in the delivery package. Comparators provide access to measurement data over an Ethernet network.

The signals of the navigation receiver's second mark and the RF available for the customer`s use are generated simultaneously on two high-frequency outputs of the receiver board. In the presence of stable reception of signals from satellites of the GLONASS and GPS radio navigation systems, the board ensures the operation of the RF in the frequency binding mode according to the signals of the second timestamp (the so-called “disciplined” rubidium frequency standard mode) with a relative error of the actual value of the RF frequency of no more than ± 5.0.10-12.
