Note :
• The AF level shows the value when the following referencesignal is
supplied to the ANTENNA A and B IN connectors from a SSG.
J1101
RF : Level input 60 dBµ
FM : ±5 kHz deviation at 1 kHz modulation
0 dBµ = 1 µV (at no load)
0 dBµ = _133 dBm (0 dBm = 1 mW, 50 Ω load)
0 dBV = 1 Vrms
• For measuring points (A to F), see the schematic diagram.
