FM modulation
RF Explorer Signal Generator RFE6GEN does not directly create FM or AM modulation signals, but can be
easily used to produce low rate modulation including SINAD signals using Frequency Sweep.
For a FM modulation of 1 KHz tone typically used for SINAD, proceed as follows:
 Select the Start Frequency the value you need (e.g. 2.000000GHz)
 Select the Stop Frequency the FM deviation you need. For instance, for a 5KHz deviation, set exactly
5KHz above (e.g. 2.000005Ghz)
 Select the Frequency Step same value as FM deviation (e.g. 5KHz)
 Select the Step Delay. For a 1KHz tone, you need 1ms delay, therefore define Step Delay:00.001
 Select RF power you need and start transmission using Frequency Sweep operational mode.
With this technique the highest rate tone generated is 1 KHz (which correspond to 1ms step delay). With a
2ms step delay, frequency tone is 500Hz, etc.
