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
