Optical Sampling Modules
3.
Using a controller (such as a PC, Macintosh, or workstation) attached to the
main instrument via GPIB, download the waveform.
NOTE.
Alternatively, you can use the Save Waveform, Copy Waveform, or a
network connection to transfer a waveform curve to a spreadsheet, ASCII
fi
le, or
other application.
4.
Using the available controller software, such as LabVIEW, perform a Fourier
Transform on the waveform to transform the time-domain impulse response
to a scalar frequency response.
5.
Normalize the Fourier Transform result such that DC or low frequency is
0 dB
.
6.
Plot the frequency response.
7.
Check that the optical sampling module meets the performance requirements
for the bandwidth setting chosen, as noted in the module test record.
8.
Repeat steps 1 through 7 for the remaining bandwidth settings for the optical
module under test (refer to the module test record).
9.
In the Vert Setup dialog box, select a Filter (see the test record for
fi
lters
available for the optical sampling module under test).
10.
11.
Refer to the module test record and check that the optical sampling module
meets the limits listed for the tested
fi
lter.
12.
Repeat steps 9 through 11 for each of the
fi
lters available for the optical
sampling module that you are testing.
80C10, 80C10B, 80C10C,
and 80C25GBE Test
This procedure checks the minimum optical bandwidths and the reference receiver
frequency responses of the 80C10, 80C10B, 80C10C, and 80C25GBE Optical
Sampling Modules only. To test bandwidths and responses minimum of all
other optical sampling modules, use the
80C01-80C09, 80C11, 80C11B, 80C12,
80C12B, 80C14, and 80C15 Procedure
instead. (See page 224.)
