1-3-3. MEASUREMENT CONDITIONS & GENERAL SPECIFICATION
1-3-3-1. MEASUREMENT CONDITIONS
The measurement condition of FM radio part
1) State of control part of receiver (When available)
-LOUD ------------------------ OFF
-LOCAL/DX SWITCH ----- DX
-MUTE SWITCH ------------ OFF
-MONO / STEREO ----------- MONO except stereo mode.
2) Standard measurement input signal
Carrier wave frequency
- Makes 90.1MHz, 98.1MHz, 106.1MHz as a standard and considers the channel space for the digital tuning radio
and selects the nearest frequency from the specified frequency.
- If there is an outside interference, it's possible to move it to the nearest frequency.
- Reference carrier wave strenth : 1mV(60dBuV)
Modulation
- MONO : 1KHz 30% (22.5KHz DEV.)
- STEREO : 1KHz 60% (45KHz DEV.) / L+R=45%, L-R=45%, PILOT =10%
- RDS(OPTION) : MPX=40%(L+R=15%,L-R=15%, PILOT=10%) RDS(57KHz)= 2.66% (
1.2KHz) DK (125Hz) :
30% AM / BK : 60% AM
- Pre-emphasis : Set as 50uS when needed to measure FM audio response.
3) SSG matching pad
4) Receiver tuning : Indicated frequency of receiver and carrier wave frequency should be matched.
Measurement condition of AM radio part
1) Standard measurement input signal
Carrier wave frequency
- Makes 603KHz, 999KHz, 1404KHz as a standard and considers the channel space for the digital tuning radio and
selects the nearest frequency from the specified frequency.
- If there is an outside interference, it's possible to move it to the nearest frequency.
- Standard LW band test frequencies are 160KHz, 220KHz, 280KHz and considers the channel space for the digital
tuning radio and selects the nearest frequency from the specified frequency.
- If there is an outside interference, it's possible to move it to the nearest frequency.
- Reference carrier wave strenth : 5mV(74dBuV)
Modulation : Standard modulation : 400Hz, 30%
2) SSG matching pad
1-4. REFERENCE CONDITION
