Performing Tests

Step 7. Scroll to the Use Reference Radio field and press the knob to toggle it to the desired

mode.

If you select YES, the Test Software will lead you through a step-by-step process that

uses one radio in the face to set a

−

39 dBm reference level at the TX SIG MON jack. The

reference level becomes a known good drive level input to the LAC preamplifier. This

allows the LAC preamplifier to be adjusted properly for the desired output level. Once

the LAC preamplifier is adjusted properly, all other radios may be adjusted by simply

setting the potentiometer on each radio front panel.

Also, if you select Yes, the Do you need assistance? field will appear immediately

below. Press the knob to toggle the field to the desired setting. If you understand the

testing process and wish to have the Test Software perform it as automatically as

possible, select No. If you wish to have the Test Software display informational screens at

appropriate points in the testing process to assist you in performing the operations,

select Yes.

If you select NO, the Test Software will assume that the LAC preamplifier is adjusted

properly for the power level for the face and the power output for each radio defined in

the frequency plan, as measured at the Base Station RF Antenna Port, by adjusting the

potentiometer on the radio front panel.

Step 8. Scroll to the Send Commands to MSC field and press the knob to toggle it to the desired

mode.

Select YES for automated testing using a PC for control.

Select NO to control the Base Station using another method.

Step 9. Press the

k1 (Proceed) key. The Test Software will display prompts to guide you through

a step-by-step process for adjusting the power of each radio in the face. If you selected a

reference radio, the Test Software will also guide you through the process of setting the

reference radio. During the process, the Test Software will display prompts directing you

to make connections, make inputs to the Test Software, turn radios on and off, and make

power adjustments.
