Operational Description

1 Memorandum Date: 05/01/00 Re: Model 48020 Circuit Description The 900 MHz “Hand-Held Monitor and Television" model 48020 will be referred to as the equipment under test (EUT) in this report. The EUT is a nursery monitoring system designed to be a high quality audio, color video monitor for home use. This monitor will transmit audible sounds and color video to the Parent Unit. The frequency band chosen for this product is the 902-928 MHz band. This product is part of an ongoing family of nursery monitors provided by Safety 1 st . The Child unit operates on one of three RF channels. An external switch controls the channel selection. Device Operation When in transmit mode the microphone picks up the room sounds and amplifies the signal through an audio amplifier the color ccd camera picks up video in color under normal light conditions and in night mode uses infra red to see images. The audio signal is controlled by an automatic gain control (AGC) circuit to limit the FM modulation. The amplified audio signal is coupled directly into the audio input of the Motorola MC44355 chipset. The video signal is picked up by an image sensor. A light sensor and control determines whether there is enough light in the room and activates the LED's for night mode if necessary. The image sensor then couples the information into the Video input of the Motorola MC44355 chipset. The video and audio is then combined in the Motorola MC44355 chipset and transmitted (RF Out) through an impedance matching network, attenuator, and tank circuits to the antenna. An AC/DC wall adapter powers the unit.

TEST PROCEDURES. Radiated test procedure The EUT, associated cables and peripheral devices are placed on the supporting table and any support equipment is placed off the site. The EUT is turned on and any necessary operating or test software installed and allowed to warm up. The frequency band from 30 MHz to 40 GHz is scanned. When an emission is found the emission is maximized by varying the bundle position of the connecting cables, the antenna height, the antenna polarization (vertical and horizontal) and the table orientation (360 degrees). The maximum reading is recorded and the next signal is searched for. Conducted test procedure The power line of the EUT is connected to the LISN (Line Impedance Stabilization Network). A measurement of the emissions are made from the power line for both phase and neutral on the analyzer in the frequency range from 450 kHz to 30 MHz. The maximum readings are recorded for each phase. All measurements are made according to the procedures defined in: "ANSI C63.4-1992 Standard Methods of Measurement of Radio Noise Emissions from Low-Voltage Electrical and Electronics Equipment in the Range of 9 kHz to 40 GHz, American National Standard for (ISBN 1-55937- 215-5).
