|
|
1. |
| To determine appropriate settings for attenuator boards, be- | |||
|
| gin by measuring signal levels at the various ports (use either | |||
|
| Option 1 or 2). |
|
| |
|
| Important |
|
| |
|
| The cables should be removed from all but one port at a time. | |||
|
| This allows the one connected port to come on line and oper- | |||
|
| ate, thus allowing measurement of signal level. | |||
|
|
|
|
|
|
2. |
| Sequentially go through the ports, and measure and record | |||
|
| the signal level of the response | |||
