RF OUT
The RF out F connector provides the RF output signal from 53 to 857 MHz with a level of 45 to 61 dBmV. The
impedance is 75 ohm.

impedance is 75 ohm.
RF MON
The RF Monitor F connector provides a means of checking the RF output without disconnecting it from service. The
RF Monitor will provide an output 20 dB down from the RF output. The test cable length (and return loss) should be
kept to a minimum to maintain the 20 dB coupling accuracy.

IF IN
The IF Input F connector accepts an input signal at 44 MHz with up to a 6 MHz bandwidth from a 75 ohm source.
The level should be from 25 to 35 dBmV.
