To output an FM waveform
1. Select a waveform and
then push the front-panel
Mod button.
In this example, use
the
sine waveform as an
output waveform (carrier
waveform).
2. Press Mod.
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 in the rear
panel to input 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 Frequency 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 the
sum of upper limit of carrier
frequency 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
