271 Users Manual Trigger and burst Phase-coherent signal keying: each positive edge of the trigger signal will produce one burst of the carrier, starting and stopping at the phase angle specified by the start/stop phase setting. Carrier frequency: Carrier waveforms: Number of cycles: Trigger repetition rate: Source: 0.1 mHz to >1 MHz All 1 to 1023 (resolution 1 cycle) or 0.5 to 511.5 (resolution 0.5 cycle). dc to 50 kHz internal, dc to 1 MHz external. Manual (front panel key), internal trigger generator, external signal or remote interface. Gated Non-phase coherent signal keying: the output carrier wave is on while the gate signal is high and off while it is low. Carrier frequency: Carrier waveforms: Trigger repetition rate: Gate signal source: From 0.1 mHz to 10 MHz. All dc to 50 kHz internal, dc to 1 MHz external. Manual (front panel key), internal trigger generator, external signal or remote interface. Sweep Carrier waveforms: Sweep modes: Sweep width: Sweep time: Markers: Sweep trigger source: All Linear or logarithmic, single or continuous. From 0.1 mHz to 10 MHz in one range. Phase continuous. Start and stop frequency may be set independently. 10 ms to 999 s with 3 digit resolution. Two, variable during sweep, available at the rear panel socket. The sweep may be free run or triggered manually (front panel key), by an external signal or through a remote interface. Amplitude Modulation Carrier frequency: Carrier waveforms: Depth: Internal source: External: From 0.1 mHz to 10 MHz. All. Variable 0 to 100% typical, resolution 1 %. 1 kHz fixed sine wave or 0.005 Hz to 50 kHz square wave. See VCA In below. Frequency Shift Keying (FSK) Phase coherent switching between two selected frequencies at a rate defined by the switching signal source.
