Examples of Measurement Results
<< Repeated Pulse Measurement Mode >>
Example 1: "Over-Level" message
appears because the input signal
level is too high. Adjust the level
so that the "Over-Level" message
disappears and 4 to 9 LEDs of the
level meter illuminate.
<< Continuous Measurement Mode >>
Example 1: The input signal level
is too high and all of the level meter
LEDs illuminate. Adjust the level so
that 4 to 9 LEDs of the level meter
illuminate.
Example 2: The phase is judged
properly but the input signal
waveform is truncated. To show the
whole waveform, switch the input
level range. Alternatively, decrease
the test signal output level or the
device's output level to lower the
signal level fed to the PHA-1.
Example 2: The input signal level is
too low and the Display shows "Low-
Level." Adjust the level so that the
"Low-Level" message disappears
and 4 to 9 LEDs of the level meter
illuminate.
Example 3: The input signal level is
too low and the Display shows "Low-
Level." Adjust the level so that the
"Low-Level" message disappears and
4 to 9 LEDs of the level meter illuminate.
If no level meter's LED illuminates,
confirm whether the connection is
properly done and the power to the
subject device is turned on.
Example 3: The signal level is
properly adjusted and the incoming
signal's entire waveform is displayed.
In this example, the shape of the
waveform fed into the PHA-1 differs
from that of the test waveform.
Example 4: The signal level is
properly adjusted and the incoming
signal's entire waveform is displayed.
Please note that this is because that
the test waveform has been effect-
processed by the subject device and
is not a malfunction or failure.
