Page 2-12 V10/V7.5/V5/V3.5 Installation and Operation ManualIssue 3.5 Section 2 Preparation for Use and Installation2.2.15.1 RF Monitor SamplesA true sample of the RF output voltage isprovided on the RF power probeassembly’s (A42) RF MONITOR BNCconnector (J3) at the output of thetransmitter. This output should be appliedto a modulation monitor with 50 Ω inputimpedance. It may also be monitored byan oscilloscope during maintenanceprocedures. Nominal levels (for ratedpower) are as follows:Transmitter, Mode, Power RF MonitorV10, FM, 10,000 W 2.5 VV10, FM+HD, 7,300 W 2.2 VV10, HD, 2,800 W 2.2 VV7.5, FM, 7,500 W 2.2 VV7.5, FM+HD, 5,480 W 1.9 VV7.5, HD, 2,100 W 1.9 VV5, FM, 5,000 W 1.7 VV5, FM+HD, 3,650 W 1.6 VV5, HD, 1,400 W 1.6 VV3.5, FM, 3,750 W 1.5 VV3.5, FM+HD, 2,740 W 1.4 VV3.5, HD, 1,050 W 1.4 VTrue samples of the IPA amplifier(s)output voltage are provided on the IPAsplitter’s (A21 and A22, if applicable) IPARF MONITOR BNC connector (J3) at therear of the transmitter. These outputsshould be applied to a modulation monitorwith 50 Ω input impedance.
