Paths FM 1 and FM 2 are summed internally for composite modu-
lation. Either path may be switched to any one of the modulation
sources: Int, Ext 1, Ext 2. 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.
1. Parentheses denote typical performance.
2. Calculated from phase noise performance in CW mode only at +2.0 dBm for standard instruments, +5.0 dBm with Option UNB.
3. For other frequencies, data rates, or bandwidths, please contact your sales representitive.
4. Since the internal modulation source operates over 0.1 Hz to 50 kHz, FM rates above 50 kHz must be supplied externally.
5. Refer to frequency bands on page 4 to compute specifications.
6. At the calibrated deviation and carrier frequency, within 5 °C of ambient temperature at time of calibration.
