when the ac–coupled signal to the EXT 1 INPUT is <
0.97 V
This annunciator (Options UNT, UNU, or UNW only or
EXT2 LO/HI
on the E8663D) is displayed as either EXT2 LO or
EXT2 HI. This annunciator appears when the

UNT, UNU, or UNW only or on the E8663D) indicates
whether active modulation formats have been enabled
or disabled. Pressing the Mod On/Off hardkey enables
or disables all active modulation formats (AM, FM, ΦM,
Pulse, or I/Q) that are applied to the output carrier
signal available through the RF OUTPUT connector. The
Mod On/Off hardkey does not set up or activate an AM,
FM, ΦM, Pulse, or I/Q format; each individual
modulation format must still be set up and activated
(for example, AM > AM On) or nothing will be applied to
the output carrier signal when the Mod On/Off hardkey
is enabled.
