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).

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.
