Country Code to ensure compliance with FCC

regulations.

- Country Select the new country.

- I agree to these terms of use Check this box; you

must agree to the Terms of Use to use the product.

- Accept Saves your change.

Channel Bandwidth Select the appropriate channel size:

10, 20, 30, 40, or 50 MHz.

Master TX Duty Cycle Use this to change the duty cycle

of the RF link (the Master’s TX percentage). Choose one of

the following values: 25%, 33%, 50%, 67%, or 75%.

Output Power (EIRP) Defines the maximum average

transmit output power (in dBm) of the AF-5X. To specify

the output power, use the slider or manually enter the

output power value. The transmit power level maximum is

limited according to country regulations.

Note: The Antenna Gain and Cable Loss should be

configured before the Output Power. This is because

the range of the Output Power field is affected by the

Antenna Gain and Cable Loss values – changing the

antenna gain or cable loss adjusts the maximum and

minimum values you can select using the Output

Power slider. Since the Output Power already includes

the antenna gain and cable loss, it represents EIRP;

therefore, the value of Output Power is actually the

total power the radio is transmitting over the air. The

current transmit power is displayed by the TX Power

EIRP setting on the Main tab.

Note: The AF-5X may limit the output power to a

value less than the value specified by this field, to

comply with regulatory region requirements. For

a list of maximum output power values by country

and region, refer to “Frequency Ranges and Power

Levels per Country/Region” on page 41.

Antenna Gain Enter the gain in dBi of the antenna that is

used in your installation. An improper value could cause

DFS false detections when operating on DFS frequencies.

Cable Loss Enter the cable loss in dB of the cable that is

used in your installation. An improper value could cause

DFS false detections when operating on DFS frequencies.

Maximum Modulation Rate or Modulation Rate Higher

modulations support greater throughput but generally

require stronger RF signals and a higher Signal-to-Noise

Ratio (SNR). By default, Automatic Rate Adaptation is

enabled, and Maximum Modulation Rate is displayed.

This allows the AF-5X to automatically adjust the

modulation rate to changing RF signal conditions. Under

certain conditions, you may prefer to lock the Maximum

Modulation Rate to a lower setting to improve link

performance.

When Automatic Rate Adaptation is disabled, Modulation

Rate is displayed. Lock the Modulation Rate to the setting

of your choice.

Select one of the available modulation rates:

• 8x (256QAM MIMO)

• 6x (64QAM MIMO)

• 4x (16QAM MIMO)

• 2x (QPSK MIMO)

• 1x (½ Rate QPSK xRT)

• ¼x (¼ Rate QPSK xRT)

Frequency Settings

The Valid Frequencies for your Country Code selection are

displayed. Ensure that you use frequencies that comply

with the local country regulations.

Frequency Enter a valid frequency. The current state is

displayed.

Note: The Master and Slave should have the same

Frequency setting.

DFS Frequencies

If you have Dynamic Frequency Selection (DFS)

frequencies, then you have three sets of Frequency

options.

Frequency 1-3 Enter a valid frequency (the same

frequency will be used for both transmit and receive). The

Current State is displayed.
