Phase Modulation (PM)
Internal modulation only; Specifications for modulated CW signal
PM Deviation
Range: 0 rad. to 160 rad., or [40 MHz ÷ Modulation Rate] (smaller value)
Resolution: 0.001 rad.
(Output Level: ≤+4 dBm, 100 kHz + 2 × (Modulation Rate + 2 × PM Deviation × Modulation Rate) ≤ f ≤ 2.7 GHz, after CAL)
Deviation Accuracy
<2% of setting + 0.02 rad. (nom.) (Modulation Rate: 1 kHz, ΦM Source = Sine, PM Deviation: ≤20 rad.)
Distortion
<0.2% (nom.) (Modulation Rate: 1 kHz, ΦM Source = Sine, PM Deviation: 20 rad.)
Modulation Frequency Response
Applied only to the internal modulation (Int) when MG3710A-050/080 is not installed.
