Certification Information

Certification Information
F.C.C. Information
Electronic test equipment is exempt from Part 15 compliance (FCC) in the United States. However, compliance verification tests are systematically performed on most EXFO equipment.
 Information
Electronic test equipment is subject to the EMC Directive in the European Union. The EN61326 standard prescribes both emission and immunity requirements for laboratory, measurement, and control equipment. This unit has undergone extensive testing according to the European Union Directive and Standards.
Use of shielded remote I/O cables, with properly grounded shields and metal connectors, is recommended in order to reduce radio frequency interference that may emanate from these cables.

Inserting and Removing Test Modules

CAUTION
Never insert or remove a module while the controller unit and its expansion units are turned on. This will result in immediate and irreparable damage to both the module and unit.
To insert a module into the controller or expansion unit:
1. Exit IQS Manager and turn off all your units.
2. Remove the protective cover from the desired unused module slot.
2a. Pull the retaining screw knob firmly towards you and release the
bottom of the cover.
2b. Gently pull the top of the protective cover downwards, to remove
it from the unit grooves.
3. Position the module so that its front panel is facing you and the top and bottom protruding edges are to your right.

4. Insert the protruding edges of the module into the grooves of the unit’s module slot.
5. Push the module all the way to the back of the slot, until the retaining screw makes contact with the unit casing.
6. While applying slight pressure to the module, turn the retaining screw knob (located at the bottom of the panel) clockwise until the knob is horizontal.
This will secure the module into its “seated” position.

Inserting and Removing Test Modules
The module is correctly inserted when its front panel is flush with the front panel of the controller or expansion unit.
When you turn on the controller unit, the startup sequence will automatically detect your module.
Note: You can insert IQ modules into your controller or expansion unit; the
IQS Manager software will recognize them. However, the IQS-1100/IQS-1500 locking mechanism (retaining screw) will not work for IQ modules.
To remove a module from your controller or expansion unit:
1. While pulling gently on the knob, turn it counterclockwise until it stops.
The module will slowly be released from the slot.

2. Place your fingers underneath the module or hold it by the retaining screw knob (NOT by the connector) and pull it out.
CAUTION
Pulling out a module by a connector could seriously damage both the module and connector. Always pull out a module by the retaining screw knob.
3. Cover empty slots with the supplied protective covers.
3a. Slide the top of the protective cover into the upper grooves of the
unit.
3b. Snap the cover into place by pushing the retaining screw knob.
Failure to reinstall protective covers over empty slots will result in ventilation problems.

Starting the Power Meters Application
IQS-1500
When you start the IQS-1500 Calibration Power Meter application, you will notice a thermometer icon under the function tabs. This is the warmup period indicator; it will remain on until the initial warmup time is over (approximately 15 minutes).
If the external temperature fluctuates outside the normal operation temperature, the thermometer icon will reappear until the temperature is back within the required range (23
o
C ± 5 oC).
You can still perform measurements while the icon is present, but EXFO recommends postponing critical measurements until the warmup period is over, as you might not benefit from the maximum stability and precision your power meter can offer.

Naming Channels

Naming Channels
A user-selected name can be given to each power meter channel. The channel name appears in the main window. Naming individual channels is particularly useful when you need to display more than one power channel at the same time, especially in Monitor Window mode with several optical power meters displayed simultaneously. The name should be as self-explanatory as possible (for example, Power-Fiber 3).
To enter a channel name:
1. Click the Settings function tab.
2. Type in a self-explanatory name in the Name box.
3. Click Apply to confirm your new setting.

Wavelength list

Selecting the Wavelength

Selecting the Wavelength
When taking accurate measurements, your power meter must be set to the correct wavelength to compensate for the photodetector responsivity at the incident wavelength. Ideally, the power meter’s wavelength should be set as close as possible to that of the optical source being used.
The wavelength must be selected from the wavelength list. To set the wavelength list, see Managing Wavelength Lists on page 22.
To select the wavelength (either from the Instrument or Settings function tab):
1. Select the wavelength using the arrow buttons next to the λ list.
2. If you are in the Channels tab of the Settings function tab, click Apply
to confirm your new setting.

Managing Wavelength Lists

Managing Wavelength Lists
The wavelengths you want to use with your IQS-1100/IQS-1500 must be entered in the Wavelengt h list. Please refer to the Certificate of Compliance supplied with your power meter for information on the wavelength range.
To add a wavelength to the list:
1. From the Settings function tab, select the Lists tab.
In the New Value list, enter the wavelength value to be added.
2. Click to confirm the new wavelength.
Note: A warning message is displayed if the new wavelength is not within the
power meter’s wavelength range.
To delete a wavelength from the list:
1. From the Settings function tab, click the List tab.
2. From, the Wa v e l e ngth list, select the wavelength to be deleted.
3. Click to confirm the operation.
Note: It is not possible to delete a wavelength that is currently being used.
