FEASA LED ANALYSER

FUNCTIONAL VERSION

Sequence Capture Mode

GetFrequency## - Returns the frequency and duty cycle of Led

Transmit Receive

getfrequency## Fff.f Hz xxx.x %

Where:

## represents the Fiber Number and is a value in the range 01 - 20.

fff.f Hz represents the Frequency in Hertz.

Xxx.x % represents the Duty Cycle in Percentage.

Description

This command reports the Frequency in Hertz and the Duty Cycle in % of the Led under test

after the capture is complete.

Example:

The PC transmits getfrequency01 to the LED Analyser to instruct it to report the Frequency

and duty cycle of fiber 1

getfrequency01

123.4Hz 067.8%
