Standard

Two standard methods for field-strength measurement are described. The standard-antenna method consists of measuring the received power or open-circuit voltage developed in a standard receiving antenna by the field to be measured and computing the field strength from the measured voltage and the dimensions and form of the standard antenna. The standard-field method consists of comparing voltages produced in an antenna by the field to be measured and by a standard field, the magnitude of which is computed from the dimensions of the transmitting antenna, its current distribution, the distance of separation, and effect of the ground. The measurement procedures are outlined, including calibration of commercial field strength and extension of the methods to microwave frequencies. Methods for measuring power radiated from an antenna under several different conditions are briefly presented, and the important considerations for securing useful and accurate measurements are described.<>

RP 291:2009 - Assigned Ancillary Identification Codes
March 18, 2009 - Society of Motion Picture and Television Engineers

SMPTE RP 291-2009 is withdrawn and superseded by SMPTE ST 291:2010. All the information is now a register defined by the standard, so there is no longer a need or use for the RP.

ST 291:2006 - Ancillary Data Packet and Space Formatting
September 20, 2006 - Society of Motion Picture and Television Engineers

This standard specifies the basic formatting structure of the ancillary data space in digital video data streams in the form of 10 bit words. Application of this standard includes 525-line and 625-line standard definition digital television interfaces (component or composite), and high definition di...

291-1969 - IEEE Standards Report on Measuring Field Strength in Radio Wave Propagation
January 1, 1969 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Most measurements with which radio wave propagation is concerned involve the measurement of field strength. Thus, the determination of power radiated from an antenna depends principally upon the measurement of field strength, especially in the low-frequency and medium-frequency bands. Standard metho...
