FM path 1 and FM path 2 are summed internally for composite modulation.
The FM 2 path is limited to a maximum rate of 1 MHz. The FM 2 path must
be set to a deviation less than FM 1 path.

1. All analog performance above 4 GHz is typical.
2. For non-Option UNJ units, specifications apply in phase noise mode 2 [default].
3. Refer to frequency bands on this page to compute specifications.
4. Parentheses denote typical performance.
5. At the calibrated deviation and carrier frequency, within 5 °C of ambient temperature
at time of calibration.
