3 Getting Started with Your
High Performance Power Meter
This chapter contains information on how to insert and remove test modules. You will also find how to connect your optical head to your power meter and how to start and exit the application.

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.
CAUTION
To avoid damaging your unit, use it only with modules approved by EXFO.

Inserting and Removing Test Modules
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-1700 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.
CAUTION
High Performance Power Meter 13
Failure to reinstall protective covers over empty slots will result in ventilation problems.

Connecting the Optical Head to the Power Meter

Connecting the Optical Head to the Power Meter
To connect the optical head to the optical head interface, use the provided cable. Ensure that the connector key is aligned with the port’s corresponding notch; once the key and pins are properly aligned, the connection should be made easily.
CAUTION
Do not force the connector into the port if the pins do not seem to be correctly aligned with the corresponding holes. Forcing the connector could permanently damage the pins.
Once you have connected the optical head to the interface and started the application (as explained in Starting the High Performance Power Meter Application on page 15), you should see the channel or channels (on a multiple-channel power meter) in the data display.
If the optical head is not connected to its channel, you will notice that the display is different and you cannot perform measurements on this channel until you have connected the head properly.

Securing the Optical Head onto Your Work Surface

Securing the Optical Head onto Your Work Surface
Your OHS-1700 Optical Head can be used with a tripod. A metric-based screw hole is located on the left side of the head and bears the inscription “M6 X 1” and an imperial-based screw hole is located on the right side and bears the inscription “1/4-20”.
Once you have installed the head onto the tripod, tighten the tripod screw to prevent it from turning; which would compromise your test results.

Starting the High Performance Power Meter Application

Your IQS-1700 High Performance Power Meter module can be configured and controlled from its dedicated IQS Manager application.
Note: For details about IQS Manager, refer to the IQS platform user guide.

Starting the High Performance Power Meter Application
The main window (shown below) contains all the commands required to control the High Performance Power Meter:
Note: When using a multichannel power meter with different optical heads, the
settings (such as the wavelength list) used by the application are those detected on the highest channel number. For example, if you use a Low-PDL head on channel 2 and a high-power head on channel 3, the high-power head settings will take precedence. If you move the head from channel 3 to channel 1, the Low-PDL head will be used for settings instead.
