Sweep, hop and list modes

Sweep, hop or list parameters

Frequency, level, phase, frequency and level, phase and level

Discrete sweep or list points

2 to 10 001 (or 2 to 1750 points when saving power-up settings to device)

Hop is a special case of sweep

with only two points.

Frequency stepping dwell time

27 µs to 65 500 µs (or 27 µs to 1750 µs when saving power-up settings to device)

Excepting any step exceeding

±2.2 GHz to or from the frequency

band 7.0 GHz to 8.0 GHz,

minimum dwell 100 µs.

Modulation

Frequency range internal sine source

10 Hz to 5 kHz
