3.2.11 Selecting the Analog Output Response Speed
(Analog Waveform Observation)
Set the analog output response speed when measuring a flashing light source using the analog
output connector.
☞
2.2.5 Using the Analog Output Connector
This setting switches the response speed of the photo-receiver circuit.
The response speed is the time required for the analog output of the instrument to reach 90% of
the peak value when measuring an LED driven by a square wave from a function generator.
When the product is shipped, this setting is NORMAL. Perform general measurement with this
setting at NORMAL.
FAST
:
The response speed of the photo-receiver circuit is increased.
Set this to observe the flashing state of a display or an LED light source, for example.
To observe the flashing state of a light source, connect an oscilloscope, for example,
to the analog output connector on the instrument. The response speed differs
depending on the measurement range (approx.5 milliseconds to 0.05 milliseconds).
NORMAL:
The response speed of the photo-receiver circuit is decreased.
Set this to measure luminance chromaticity or continuously measure luminance, for
example, of a fixed light or a flashing light such as a high-frequency flashing light,
fluorescent light, and a CRT.
Also, use this setting when a recorder or other device is connected to the analog
output connector and you are to observe light source fluctuations over a long period
of time.
・
When performing analog observation using the analog output connector, make the
settings at "Setting the Measurement Mode" and "Selecting Filters in the Tristimulus
Value Fixed Mode."
