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

2. 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).

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

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 1V
