Measure", press OK. At the top of the measurement graph,
the O/E Measurement is now indicated.
14 Now disconnect the LCA RF Input from the RF output
connector of the optical test set and terminate the LCA
RF Input. The measurement now corresponds to the dark
level for O/E minimum measurable responsivity. Save a
measurement trace under the name oeDark.
15 If the LCA has another wavelength available, repeat Steps
nd
11- 13 for the 2
files in a separate directory for the 2
16 In the User Interface Display, select the electrical- to-
optical measurement by starting the E/O Measurement
mode. Set the correct wavelength in the next macro setup
window and with the wavelength switch on the optical
test set. If Measure Mode is available, choose Single- End.
When the instrument reports "Ready to Measure", press
OK. At the top of the measurement graph, the E/O
Measurement is now indicated.
17 Reattach the LCA RF Input to the RF output connector of
the optical test set. The traceable calibration of the LCA
receiver has now been loaded and the trace displays the
conversion efficiency of the LCA transmitter. Save a
measurement trace under the name eoLight.
18 Disconnect the fiber patch cord and connector adapter
from the LCA Optical Input so that the Optical Input can
be darkened with a black rubber cap. Disconnect the LCA
RF Output and connect it to the 50 Ohm termination. The
measurement now represents the dark limit for the E/O
minimum measurable responsivity. Save a measurement
trace under the name eoDark.
19 If the LCA has another wavelength available, repeat Steps
nd
15- 17 for the 2
files in a separate directory for the 2
20 If the LCA has Option #302 or #303, then exit the E/O
macro procedure by starting E/E Measurement mode,
which restores standard network analyzer functionality.
Then change the sweep setup by changing parameters
according to the table below, and then repeat the
electrical calibration of the network analyzer for the new
parameters, as in Step 2.
