Testing Fibers in Advanced Mode
66 MAX-700
Enabling the High-Resolution Feature
To use the same pulse and acquisition time for all wavelengths:
1. From the button bar, press OTDR Setup, then go to the Acquisition
tab.
2. Select the Apply settings to all wavelengths box.
The modifications you make to pulse, time, and range settings will now be
applied to all wavelengths.
Enabling the High-Resolution Feature
You can select the high-resolution feature to obtain more data points per
acquisition. This way, the data points will be closer to each other, which
will result in a greater distance resolution for the trace.
Note: When you test with the high-resolution feature, you should use a longer
averaging time to maintain a signal-to-noise ratio (SNR) that will be
equivalent to the one you would have got with the standard resolution.
Note: You can use high resolution with any test mode (except when you monitor
fiber in real time), but you must be in Advanced mode to select it.
IMPORTANT
To test using the high-resolution feature, the acquisition time must
be of at least 15 seconds.
