Frequently Asked Questions
What is the difference between a frequency counter and a frequency analyzer?
A frequency counter measures parameters such as frequency, period, pulse width, rise time, and time interval. A frequency analyzer adds advanced capabilities such as modulation domain analysis, Allan deviation, statistical analysis, and graphical signal evaluation.
When is a multi-channel frequency analyzer required?
A multi-channel analyzer is suited to applications requiring simultaneous and independent measurements across multiple signals or devices. It reduces the need for separate counters and enables direct timing and frequency comparisons.
Can one frequency reference support multiple test instruments?
Yes. Multiple buffered frequency and timing outputs can distribute stable reference signals to several counters, analyzers, testers, or automated test systems without requiring a separate reference for each instrument.
What does Allan deviation measure?
Allan deviation measures frequency stability over different observation periods. It helps identify noise, drift, and oscillator behaviour that may not be visible through a standard frequency measurement.
How does a GNSS-disciplined Rubidium frequency reference work?
It combines the short-term stability of a Rubidium oscillator with the long-term accuracy of GPS or another GNSS time source. This provides stable frequency outputs, accurate UTC alignment, and reliable holdover performance if the GNSS signal is interrupted.
Why is zero dead-time measurement important in frequency analysis?
Zero dead-time measurement captures consecutive signal cycles without gaps. This prevents short-duration events, frequency changes, and instabilities from being missed during continuous monitoring.
