Since it is reliable and easy to operate, the device is widely used in metrological centers, measuring laboratories, at the workplaces of REA developers. The memory of the comparator Ch7-1015 contains information about the main technical characteristics of domestic and foreign rubidium frequency standards presented on the Russian market, which greatly simplifies the process of checking devices in calibration laboratories. The device has a USB 2.0 communication interface with an external personal computer and application software for an external PC. The comparator Ch7-1015 has the ability to remotely control all modes of operation via a TCP protocol streaming socket and can work within an automated system.

The modular construction principle makes it easy to adapt the devices to the specific requirements of the consumer. The standards are available in four versions – H1-1011, H1-1011/1, H1-1011/2 and H1-1011/3, which differ in metrological characteristics and a set of installed devices (modules). The built-in diagnostic system allows you to quickly determine the operability and condition of the main devices of the standards. On the front panel of the devices H1-1011 and H1-1011/2 there is an LCD display and a control panel, with which you can quickly receive information about the current parameters of the devices included in the devices and adjust the frequency of the output signals. The H1-1011 and H1-1011/2 standards can receive chronometric information from GLONASS and GPS satellite radio navigation systems and use it to synchronize the local time scale and automatically adjust the actual frequency value of the built-in highly stable rubidium frequency standard. The composition of the standards H1-1011 and H1-1011/2 includes: rubidium frequency standard H1-1014; MPR-01 satellite radio navigation systems receiver module; amplifier module for highly stable sinusoidal signals (at the customer's choice): MUS-01 (3 independent outputs 10 MHz, connector type SR-50-73FV); MUS-02 (3 independent outputs of 5 MHz, connector type SR-50-73FV); MUS-03 (3 independent outputs of 1, 5 and 10 MHz, connector type SR-50-73FV); MUS-04 (6 independent outputs of 1, 5 and 10 MHz in any combination at the customer's choice, SMA connector type); MS synthesizer module with software (SMA connector type) instead of an amplifier module (at the customer's request). The scope of delivery (at the request of the customer) includes an antenna for the SRNS receiver as part of: antenna unit; mounting device; antenna cable (maximum length 60 m). The H1-1011/1 and H1-1011/3 standards include: the rubidium frequency standard H1-1013; two modules of amplifiers of highly stable sinusoidal signals (at the customer's choice): MUS-01 (3 independent outputs 10 MHz, connector type SR-50-73FV); MUS-02 (3 independent outputs of 5 MHz, connector type SR-50-73FV); MUS-03 (3 independent outputs of 1, 5 and 10 MHz, connector type SR-50-73FV); MUS-04 (6 independent outputs of 1, 5 and 10 MHz in any combination at the customer's choice, SMA connector type); MS synthesizer module with software (SMA connector type) instead of an amplifier module (at the customer's request).

Its small dimensions, weight, power consumption, and operating time allow it to be widely used as an embedded source of high-stability signals in frequency measuring devices and complexes, telecommunications systems, navigation and communication systems.

On the two high-frequency outputs of the receiver board, the signals of the second mark of the navigation receiver and the RF, which are available for the customer`s use, are generated. When receiving 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 an error of the actual value of the RF frequency for no more than ± 5.10-12

The built-in time scale shaper provides a pulse signal of 1 c at the output of the device. Its small dimensions, weight, power consumption, and operating time allow it to be widely used as an embedded source of high-stability signals in frequency measuring devices and complexes, telecommunications systems, navigation and communication systems. It includes a frequency binding module based on a pulse signal of 1 s from an external time scale or from a SRNS GLONASS/GPS receiver and a tunable frequency synthesizer with the ability to adjust the frequency via the RS-232 interface. The built-in binding module allows the device to be used when operating in automatic correction mode as a source of a highly stable signal with a frequency error of ± 5 · 10-12 per day.

Rubidium frequency standards H1-1022 are available both in the standard version and with various options that have differences in functionality and technical characteristics: option 01 is a device with high short–term stability of the output signal frequency; option 02 – a device with a low-level phase noise in the output signal spectrum; option 03 – the device has a binding module in its composition, which allows automatic correction of the frequency of the output signal according to the signal of the external time scale; option 04 – the device has a synthesizer module in its composition, which allows you to receive a sinusoidal signal of a given frequency at the output of the device in the range from 100 Hz to 100 MHz in steps of the order of 4 × 10-6 Hz; option 05 is a device with an extended range of ambient operating temperatures. Through the built-in RS-232 interface, telemetry information is collected from the device nodes, and commands to change the frequency of the output signal are transmitted. The H1-1022 frequency standards have no domestic analogues in terms of their small dimensions, weight, power consumption and operating time, as well as in terms of their numerous functional capabilities.

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.

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.
