2.10 OVERLOAD AND UNDERRANGE DETECTION
Overload detector
The instrument has the built-in overload detectors. Both A/D converter and input amplifier overload conditions
are detected. The overload in the measurement channel (in its analogue part) and the overload of the
analogue / digital converter are both detected. The “overload” indication appears when the input signal amplitude
is 0.5 dB above the declared “Peak measurement range”. This condition is checked once per second or with the
Logger Step if it is less than 1 second.
An overload is indicating by the flashing icon which is displayed during the period from the overload detection
till the end of the Integration Period. If the overload disappears to the Integration Period end, the overload icon
will not be displayed from the start of the next measurement cycle.
When an overload is detected the special marker will be recorded to the logger file with the data logging step.
The overload time is measured by the OVL result during the Integration Period and is saved in the logger file as
part of Summary Results.
