TEST POINTS and ADJUSTMENTS
The OTOT-300C features an RF Drive test point that will yield +10dBmV per
channel when the RF input level is optimum with a standard 5-42MHz CATV return
load. Connect the RF input to the transmitter and adjust the level until +10dBmV
per channel is measured on the test point. Figure 2 shows typical NPR
performance with greater than 18dB of usable dynamic range above 41dB NPR.
The unit also has a 20dB RF gain adjustment, which allows the unit to deal with
non-standard CATV return loads. The unit has a green LED to provide a positive
indication that the unit is powered and a DC test point that indicates the optical
output power (1Volt/mW).
