Paths FM1 and FM2 are summed internally for composite

modulation. Either path may be switched to any one of

the modulation sources: Ext1, Ext2, internal1, internal2.

The FM2 path is limited to a maximum rate of 1 MHz.

The FM2 path must be set to a deviation less than FM1.

1. At the calibrated deviation and carrier frequency, within 5 °C of ambient temperature at time of user calibration.

2. For f

< 2 MHz AM is usable but not specified. AM specifications apply with ALC on, and envelope peaks

< maximum specified power.

3. For AM depth settings > 90% or > 20 dB, deep AM mode is recommended.
