The module uses connectors of the SMA type. At the request of the customer, any combination of output signals is possible. When installing two amplifier modules in the above devices, the total number of output signals increases to twelve.

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 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).

The device is made in a 19-inch rack design with a 4U stand. The rubidium reference generator RRS-002 provides up to 15 independent signal outputs with a frequency of 10 MHz (5 MHz). The device is designed for long-term uninterrupted operation both in round-the-clock continuous and in session mode. The high reliability of the generator is ensured by reserving the main generator blocks and, in case of malfunction of the active signal source, automatically switching to a backup one.

The comparator CHK7-1012 has a communication interface with an external personal computer USB 2.0 and application software for an external PC. At the request of the customer, the comparator can be supplied complete with a laptop or tablet computer with installed software.

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 Ch1-1012 frequency standard is designed for mobile applications with high requirements for dimensions, weight and power consumption as an embedded signal source of high stability in frequency measuring devices and complexes, telecommunication systems, navigation and communication systems. This device can serve as a promising substitute for quartz generators in the development of high-resolution equipment, where the accuracy characteristics of a quartz generator are no longer sufficient.
