To output an FM waveform
1. Select a waveform and
then push the front-panel
Mod button.
2. Press Mod.
In this example, use
the
sine waveform as an
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
modulation type.
4.
Press Source to select
Internal or External. If the
source is External, use
the Ext Mod In connector

the external signal, the
setting of FM is finished.
If you choose Internal,
continue with the steps
below.
5.
Press Shape to select
among sine, square,
ramp, or arb as the
modulating waveform.
6.
Press FM Freq to set the
FM frequency. The range
is 2 mHz to 20 kHz
(Internal source only).
7.
Press Deviation, use the
general purpose knob to
adjust the deviation or
use the numeric keypad
and then select unit.
NOTE: The sum of deviation
and carrier frequency should
be less than or equal to that
of the upper limit of carrier
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
