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 1 MHz (high BW mode).
3. Path 1 is useable to 4 MHz for external inputs less than 0.3 V
peak
.
4. AM specifications are typical. For carrier frequencies below 2 MHz, AM is useable but not specified. Unless otherwise stated,
specifications apply with ALC on and envelope peaks within ALC operating range (–15 dBm to maximum specified power,
excluding step attenuator setting).
5. ALC Off is used for narrow pulse modulation and/or high AM depths, with envelope peaks below ALC operating range.
Carrier power level will be accurate after a Power Search is executed.
6. ALC On with Deep AM provides high AM depths together with closed-loop internal leveling. This mode can be used with a
repetitive AM waveform (frequency > 10 Hz) with peaks > –5 dBm (nominal, excluding step-attenuator setting).

Paths ΦM1 and ΦM2 are summed internally for composite
modulation. Either path may be switched to any one of
the modulation sources: Ext1, Ext2, internal1, internal2.
The ΦM2 path must be set to a deviation less than ΦM1.
