4.3 Modulation
WF1945B 4-49
 Phase modulation (PM) (
MODE
→
MODU
→ TYPE : PM)
Operation to produce a phase modulated waveform output is described below. The example is a sinewave,
1 kHz, DC offset 0 V, phase and amplitude arbitrary.
Operation:
(1) Set modulation TYPE to phase (PM)
① Press the
MODE
key, then the
MODU
key.
② Use the
and keys to produce the following display (TYPE flashes).
ＦＭ ＡＭ ＯＦＳＭ ＰＭ ＰＷＭ

③ Press the
ENTER
key, then use the and keys to produce the following display (PM
flashes).
ＦＭ ＡＭ ＯＦＳＭ ＰＭ ＰＷＭ
ＰＭ：ＴＹＰＥ ＤＥＶＩＡＴＩＯＮ ＦＲＥＱ ＦＵＮＣＴＩＯＮ
④ This sets the modulation type for phase. Press the
