The amplitude of signal source may not need calibration because you calibrate
the field at the end with calibrated probes.
You should at least check or get the signal generator calibrated if your
verification procedure is not checking (characterizing) the modulation.
EN 61000-4-3 gives some hints about amplitude modulation but the other
modulation types can be difficult to measure (Pulse, burst, phase etc.)

Subject: Re: Calibration supplier for signal generator with pulse modulation
Why would the signal source need calibration? Normally, it is the signal
measurement devices that require calibration. Further, this signal source
likely requires some amplification in order to provide the required signal
for EMI testing, so that it is the amplified output which must be measured,
not the signal generator itself.
