Multitone

The multitone signal is generated based on the settings in the tone table. The tone table contains from 1 to 4097 tones. Each tone in the table has four parameters: frequency, power, phase and state. The tone power and tone phase are relative to the power and phase of all the other tones in the signal. The tone frequency is an offset from the signal generator carrier frequency. The tone state is a quick way to enable or disable a specific tone in the table without deleting it. The multitone application provides several parameters for loading the tone table values. These include Tone Count, Tone Spacing, Phase Distribution, Phase Seed and Phase Value. Changing any of these parameters causes the tone table to be updated based on their settings. The tone table also provides an import and export function to load or save the tone parameters from an ASCII file.

The Multitone parameters are independent of the system configuration. That is to say that the parameters are always available regardless of the system configuration. However, many parameter limits are dependent on the actual system configuration. The ESG/PSG internal Arb can provide multitone signals with modulation bandwidths up to 80 MHz. The MXG internal Arb can provide multitone signals with modulation bandwidths up to 100 MHz.
