## ppm to Hz calculator

Frequency stability is the specification used in many of the RF systems viz. Crystal oscillator, frequency synthesizer and RF transceiver. The frequency output of these RF systems or components vary due to temperature, supply voltage variation, frequency aging and output load variation. There are two types of frequency stability used in RF systems, short term and long term. Both of these stabilities are specified in units of ppm (Parts per million).

A ppm to Hz calculator is a tool used to convert a
frequency expressed in parts per million (PPM) to hertz (Hz).
This calculator employs a mathematical formula to adjust a reference frequency
by the specified PPM value, ensuring precise and accurate frequency settings,
particularly in radio frequency (RF) applications.
It is a valuable tool for engineers and technicians working with RF equipment, telecommunications
and electronics, as it helps maintain frequency stability and reliability in various technological systems.
PPM indicates one part in total 10^{6} parts.

EXAMPLE of 1 ppm to Hz calculator:

INPUTS: Fc = 100 MHz , ppm = 1

OUTPUT: Frequency Variation = 100 Hz, Min. Frequency = 99999.9 KHz,
Max. Frequency = 100000.1 KHz

### PPM Formula for PPM to Hz conversion

ppm basically represents part of the whole number which will have units of the value 1/1000000. The PPM formula for PPM to Hz conversion is mentioned below.

**Conclusion** : By applying the PPM calculation formula, RF engineers can account for deviations from the reference frequency caused by factors
like temperature variations or equipment tolerances, ensuring precise signal transmission and reception in various applications.
This accuracy is crucial in maintaining the reliability and performance of RF systems.
