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.

for indicated deviation
Paths FM1 and FM2 are summed internally for composite

the modulation sources: Ext1, Ext2, internal1, internal2.
The FM2 path must be set to a deviation less than FM1.
1. Above 50 GHz, FM is useable; however performance is not warranted.
2. Through any combination of path1, path2, or path1 + path2.
3. Specifications apply in CW and list/step sweep modes. During ramp sweep operation (Option 007), 3 dB bandwidth is typically 50 kHz to 10 MHz
(FM1 path), and 50 kHz to 1 MHz (FM2 path).
4. At the calibrated deviation and carrier frequency, within 5 °C of ambient temperature at time of user calibration.
5. Above 50 GHz, phase modulation is useable; however performance is not warranted.
6. Through any combination of path1, path2, or path1 + path2.
7. Specifications apply in CW and list/step sweep modes. During ramp sweep operation (Option 007), 3 dB bandwidth is typically 50 kHz to 1 MHz
(high BW mode).
8. Path 1 is useable to 4 MHz for external inputs less than 0.3 V peak.
