1.
Select a waveform and
then push the front-panel
Mod
button.
2.
Press

output waveform (carrier
waveform).
NOTE:
You can only choose
sine, square, ramp, or arb as
a carrier waveform.
3.
Press
Type
to display
the modulation selection
menu. Select
FM
as the

general purpose knob to
adjust the deviation or
use the numeric keypad

NOTE:
The sum of deviation
and carrier frequency should
be less than or equal to that

waveform and 1 kHz. For
external source, the deviation
is controlled by the electrical
level of Modulation In
interface. +5 V add the
selected deviation, and -5 V
minus the selected deviation
