MODULATION MODES

Continuous

Continuous cycles of the selected waveform are output at the selected frequency.

Gated

Non phase-coherent signal keying - output is On while Gate signal is high and Off while low.

Carrier frequency: From 0.1Hz to 10MHz/20MHz

Carrier waveforms: All

Trigger rep. rate: dc to 100kHz external, dc to 5kHz internal

Gate source: Front panel MAN TRIG key, Internal Gate Generator,

TRIG/GATE input, or Remote Interface

Sweep

Carrier waveforms: All

Sweep Mode: Linear or logarithmic, single or continuous

Sweep Width: 0.2Hz to 10MHz/20MHz in one range. Phase continuous.

Independent setting of the start and stop frequency

Sweep Time: 50ms to 999s (3 digit resolution)

Markers: Available from AUX output. Variable during sweep

Sweep Trigger
