Device for measuring attenuation DC1-28

Mathematical processing of the measurement makes it possible to determine and display on the indicator board the relative systematic change in frequency, the average relative value of the frequency difference, the RMS relative frequency deviation, the RMS relative two-sample frequency deviation.

The voltmeter is capable of working both independently and as part of automated measuring systems with interfaces such as USB, RS-232, IEEE-488 (CPC).
