Frequency comparator CHK7-1011
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.

Rubidium frequency and time standards H1-1011/1
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 H1-1011 and H1-1011/2 standards include:
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);
