General Safety Information

The following safety requirements, as well as local site

requirements and regulations, must be observed by personnel

operating and maintaining the equipment covered by this manual

to ensure awareness of potential hazards.

Notices Notices-iiPTX-PRO User and Technical Manual

WARNING - RF Power Hazard

High levels of RF power are present in the unit. Exposure to RF

or microwave power can cause burns and may be harmful to

health.

Remove power from the unit before disconnecting any RF cables

and before inspecting damaged cables and/or antennas.

Avoid standing in front of high gain antennas (such as a dish

antenna) and never look into the open end of a waveguide or

cable where RF power may be present.

RF Exposure - Safe Working Distances

MRC provides this warning for safety purposes with the intent to

inform the user of the potential hazard of RF exposure. The

following guidelines for safe operation were derived from OET

bulletin 65, August 1997, as recommended by the Federal

Communications Commission (FCC).

The PTX-PRO 13 GHz Transmitter is a mobile transmitter

system designed to provide services to broadcast ENG users

under CFR 74 subpart F and 74.601 TV pickup stations. This

unit, operated without an antenna, will not create RF energy

exceeding 1.0 mW/cm2, the FCC limit for exposure. Once

connected to an antenna, the potential for harmful exposure will

be greatly enhanced.

In this situation, a certain distance from the radiator is to be

maintained. Calculations need to be performed to understand

what that safe margin for exposure is. This is known as the

Maximum Permissible Exposure (MPE) limit.

Note Hazardous RF radiation limits and recommended

distances may vary by country. Ensure that all

applicable state and federal regulations are

observed when using this transmitter.

Calculations provided are for common antennas often utilized in

the ENG environment. The following formula used is that

suggested by OET 65.

Calculating MPE

EIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * P

P = RF power delivered to the antenna in mW

G = Power gain of the antenna in the direction of interest relative

to an isotropic radiator

R = distance to the center of radiation of the antenna in

centimeters

S = MPE in mW/cm² (milliwatts per square centimeters)

Conversions

dBi to numeric gain = Antilog (dBi/10)

Feet to centimeters = Feet * 30.48

Centimeters to Feet = cm * .0328

4 π= 12.57

User Input

RF power delivered to the antenna = Watts

Antenna gain (referenced to isotropic antenna) = dBi

Distance from the center of radiation = Feet

Calculation steps:

Notices Notices-iiiPTX-PRO User and Technical Manual

1. [P] RF power input. Convert watts to milliwatts =

Watts * 1000

2. [G] Antenna gain dBi. Convert to numeric gain =

Antilog (dBi/10)

3. [EIRP] Multiply P * G

4. [R] Convert centimeters to feet = Centimeters * .0328

5. Square R

6. Multiply R² * 4π

7. [S] Divide (R² * 4π) into EIRP

S = Power Density in milliwatts per square centimeters.

Note: At frequencies above 1500 MHz, S must not be

greater than 1

Reference

FCC OET Bulletin 65, August 1997 - Evaluating

Compliance with FCC Guidelines for Human Exposure to

Radio Frequency Electromagnetic Fields

The example shown in Figure 1 is a typical graph for an

MRC PTX-PRO 13 GHz Transmitter and shows the

permissible exposure distance for various antennas.

Graphs and data will vary, based on the actual transmitter,

output power, frequency, and antenna utilized. The plot

provides the permissible output of the transmitter for digital

modulation

MRC, in accordance with the requirements set forth by the

FCC, provides this information as a guide to the user. It is

assumed that the users of this equipment are licensed and

qualified to operate the equipment per the guidelines and

recommendations contained within the product user guides

and in accordance with any FCC rules that may apply.
