UNCAL
Auto
When Gate is followed by a dot, the frequency of the input signal is being measured. If the dot is
not displayed, measurement has halted.
This is displayed when the unit's specifications cannot be guaranteed because the input signal
maintaining the level required to get the set resolution is not being supplied continuously.
Displays the unit's level setting and input level.
Overview
The unit displays UNCAL in the following situations, indicating the measurements are not valid.
(1) The input signal is outside of the measurable range.
(2) The measurement resolution cannot be obtained from the measurement result.
(3) You have input a pulse burst signal that could not get measurement resolution that could be set even when aver-
aged during burst carrier frequency measurement.
(4) You selected Input2 as the signal input terminal while the burst measurement mode was set.
Fig. 4-3 describes the level display of the Fig. 4-2 (4) state display in even more detail. The level display consists of an
input display showing how to handle the input signal (1) and a level display showing the power of the input signal (2).
