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.

Maximum deviation N x 80 radians (N x 8 radians in high-bandwidth mode)

Resolution 0.1% of set deviation

Deviation accuracy < ±5% of deviation + 0.01 radians

Phase modulation

17 Calculated from phase noise performance in CW mode only at +0 dBm. For other frequencies, data rate, or

bandwidths, please contact your sales representative.

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