2.6 Mod Monitor Setup
To properly interface the DAX transmitter with a modulation monitor across the 5
power levels, each power level must have a corresponding Mod Monitor Level setting.
These settings will need to be adjusted, after the power levels have been set (see
"3.3.3.3 To Set Desired RF Power Output Level" on page 3-5), to correctly drive the
mod monitor input. This is done via the GUI or by using the VT100 serial programming
capability.
NOTE:
Minimum load impedance at the Mod Monitor Out (J4) is 500 Ohms.
