The CHK7-1011 is intended for relative frequency measurements of high-stable signals by comparison them with a external reference signal or with the signal of internal Rubidium Frequency Standard. All results of measurement and automatically made calculations are presented on the color display of the Instrument .
The CHK7-1011 can test frequency stability frequency offset of Rubidium and Crystal Oscillators with 1; 5; 10; 2.048; 10.24 MHz outputs . The measurement Error is less than 2.10-12 at 1 s and 5.10-14 at 100 s averaging time.
There are internal source of the reference signal in CHK-1011 – Rubidium Frequency Standard that can be synchronized with the 1s signal from the internal GPS/GLONASS Receiver (option)
CHK7-1011 used Ethernet for connection with external PC. The serial RS-485 is available also.
All measurements can be made in mobile conditions as DC Power Supply +(27 ± 3)V can be used.
