Question 3

Under FCC rules, a device is classified as 'portable' and requires SAR evaluation when the transmitting antenna operates within what distance from the human body?

Accepted Answer

20 centimeters

Answer

5 centimeters

Answer

50 centimeters

Answer

Question 4

Why is the temperature of the tissue-simulating liquid critical to monitor during SAR measurements?

Accepted Answer

Temperature changes the liquid's dielectric properties, directly affecting measurement accuracy

Answer

It affects the probe's mechanical movement accuracy

Answer

It determines the maximum scanning speed of the robotic arm

Answer

It calibrates the RF signal generator output level

Question 5

What is the purpose of a system validation dipole (SVD) in a SAR test system?

Accepted Answer

To verify the overall SAR measurement system performance against a known reference standard

Answer

To generate calibration frequencies for the E-field probe

Answer

To measure the return loss of the device under test

Answer

To set and confirm the output power of the signal generator

Question 6

How frequently must a SAR measurement system's E-field probe typically be calibrated to maintain accreditation compliance?

Accepted Answer

Annually

Answer

Every 6 months

Answer

Every 2 years

Answer

Only before major testing campaigns

Question 7

Which phantom configuration is used when evaluating SAR for a device designed to be worn against the body in a body-worn configuration?

Accepted Answer

Flat phantom with the device at the manufacturer-specified separation distance

Answer

Head SAM phantom only at 0 mm separation

Answer

Cylindrical torso phantom with device taped to surface

Answer

SAM phantom tilted 15 degrees from vertical
