Retrieving Results
Retrieving Results
Once the measurements have been performed, it is possible to retrieve IL,
PDL, ORL curves. These curves are returned in separate commands (one
for the IL, one for the PDL, and one for the ORL).
With the provided COM objects, it is also possible to retrieve single-value
results such as:
³
Flatness
³
Bandwidth
³
Central wavelength
³
IL, ORL, PDL
³
Polarization-dependent central wavelength
³
Polarization-dependent central bandwidth
³
Crosstalk
The availability of these single-value results depends on the DUT filter type
(bandpass, notch or undefined).
Note: Single-value results cannot be retrieved using SCPI commands.
Controlling Instruments with GPIB
The GPIB communication protocol was designed to connect computers so
that information could be transmitted between them. The GPIB interface
developed for the IQS-12004B DWDM Passive Component Test System
permits you to remotely control the DWDM Passive Component Test
System modules. To do so, a GPIB controller card must be installed in your
computer.
