1. Above 50 GHz, phase modulation is useable; however performance is not warranted.

2. Through any combination of path1, path2, or path1 + path2.

Distortion < 1% (1 kHz rate, deviations < N x 800 kHz)

Sensitivity ±1 V

peak

for indicated deviation

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. To avoid distortion and clipping, signals applied with any

combination of FM1, FM2, or FM1+FM2 should not exceed 1 V
