Chapter 2, Making Measurements

Check Even-Second Clock

Steps

1

You can start with the connections shown in figure 24. You will get prompts from the

 

 

Software to change the Even-Second clock connection when needed.

 

2

In the main menu, scroll to and select Check Even Second Clock.

 

3

You will have to make a change to the connections, as shown on the display. Switch

 

 

the Even-Second clock signal from the EVEN SECOND/SYNC IN port to the

 

 

TRIGGER/QUALIFIER IN port on the Cellular Adapter. Once you have made the

 

 

connection, press the Continue (k2) key.

 

4

The Software will begin checking for a valid clock signal. This will take a few seconds.

 

 

When it has found a valid signal, you will see the message EVEN SECOND CLOCK

 

 

FOUND. If the Software finds no valid clock, you will see the message NO CLOCK

 

 

FOUND. In that case, see the documentation on your base station to verify that you are

 

 

connecting to the correct port and to see if any switches must be set to enable the clock

 

 

signal.

 

5

To go on, press the Continue (k2) key.

 

6

Reconnect the Even-Second clock signal connection to the EVEN SECOND/SYNC port

 

 

on the Cellular Adapter. After you have done this, press the Continue (k2) key to

 

 

return to the main menu.

Notes

See the section on the clock timing signal in "CDMA Measurement not

 

Correlating" in chapter 4, "Troubleshooting, on page 69."
