Modulation Source Selection
This device can select internal modulation source or external modulation source. After enabling AM function, the
default modulation source is internal. If need to change press Parameter→ModulationSource→External in turn.
17
1)
Internal Source
When modulation source is internal, modulation wave can be: sine wave, square wave, rising ramp wave, falling
ramp wave, arbitrary wave and noise. After enabling AM function, the default of modulation wave is sine wave. If
need to change it, press Carrier Wave →Parameter→Type in turn.
Square wave: duty cycle is 50%
Rising Ramp Wave: symmetry degree is 100%
Falling Ramp Wave: symmetry degree is 0%
Arbitrary Wave: when arbitrary wave is modulated waveform, DDS function generator limits arbitrary wave
length as 1kpts in the way of random selection
2)
Noise: White Gauss noise
External Source
When modulation source is external, parameter list will hide the modulation wave option and modulation frequency
option, and carrier waveform will be modulated by an external waveform. AM modulation depth is controlled by ±5V
signal level of external modulation input terminal. For example, if modulation depth value is set to 100%, AM output
amplitude is the maximum when external modulation signal is +5V, AM output amplitude is the minimum when
external modulation signal is -5V.
Modulation Shape Frequency Setting
When modulation source is internal, frequency of modulation shape can be modulated. After enabling AM function,
range of modulation wave frequency is 2mHz~50kHz (default is 100Hz). Press Parameter→Modulation Frequency
to change. When modulation source is external, parameter list will hide the modulation shape option and modulation
frequency option, and carrier waveform will be modulated by an external waveform. The range of modulation signal
input from external is 0Hz~ 20Hz.
18
Modulation Depth Setting
Modulation depth indicates the extent of amplitude variation and is expressed as percentage. Suitable setting range
of AM modulation depth is 0% to 120%, and the default is 100%. When modulation depth is set to 0%, the constant
amplitude (a half of the carrier wave amplitude that has been set) is output. Output amplitude changes as
modulation waveform changes when modulation depth is set to 100%. The instrument output a peak-peak voltage
less than ±5V (is connected with 50Ω terminal) when modulation depth is more than 100%. If need to change, press
Parameter→Modulation Depth in amplitude function interface. When modulation source is external, output
amplitude of the instrument is controlled by ±5V signal level of external modulation input terminal (Input/CNT probe)
in rear panel. For example, if modulation depth value in parameter list has been set to 100%, AM output amplitude is
the maximum when external modulation signal is +5V, AM output amplitude is the minimum when external
modulation signal is -5V.
Comprehensive Example
Firstly, make the instrument work in amplitude modulation (AM) mode, then set a sine wave with 200Hz from the
internal of the instrument as a modulation signal and a square wave with frequency of 10kHz, amplitude of 200mVpp
and duty cycle of 45% as a carrier wave signal. Finally, set modulation depth to 80%. Specific steps are seen as
following:

depth.

keyboard for setting modulation depth.

23
4.1.2 Frequency Modulation (FM)
In frequency modulation, modulated waveform is usually composed of carrier wave and modulation shape. Carrier
wave frequency will change as the amplitude of modulation shape changes.
Press Menu→Modulation→Type→ Frequency Modulation in turn to start the FM function. The device will output
modulated waveform with modulation waveform and carrier wave set currently.

noise (the default is sine wave). After selecting FM modulation, press Carrier Wave Parameter softkey to enter
carrier waveform selection interface.

Modulation Source Selection
This device can select internal modulation source or external modulation source. After enabling FM function, the
default of modulation source is internal. If need to change, press
1)
Internal Source
When modulation source is internal, modulation wave can be: sine wave, square wave, rising ramp wave, falling
ramp wave, arbitrary wave and noise. After enabling FM function, the default of modulation wave is sine wave. If
need to change, press Carrier Wave →Parameter→Type in turn.
25
Square wave: duty cycle is 50%
Lead Ramp Wave: symmetry degree is 100%
Tail Ramp Wave: symmetry degree is 0%
Arbitrary Wave: Arbitrary wave length limit is 1kpts
Noise: White Gauss noise
2)
External Source
When modulation source is external, carrier waveform will be modulated by an external waveform. FM frequency
deviation is controlled by ±5V signal level of external modulation input terminal on front panel. In positive signal level,
FM output frequency is more than carrier wave frequency, while in negative signal level, FM output frequency is less
than carrier wave frequency. Low external signal level has small deviation. For example, if the frequency offset is set
to 1kHz and the external modulation signal is +5V, FM output frequency will be the current carrier frequency plus
1kHz. When the external modulation signal is -5V, FM output frequency will be the current carrier frequency minus
1kHz.
Modulation Shape Frequency Setting
When modulation source is internal, frequency of modulation shape can be modulated. After enabling FM function,
the default of modulation shape frequency is 100Hz. If need to change, press Carrier Wave Parameter→
Modulation Frequency in turn, and the modulation frequency range is 2mHz to 50kHz. When modulation source is
external, parameter list will hide the modulation shape option and modulation frequency option, and carrier
waveform will be modulated by an external waveform. The range of modulation signal input from external is 0Hz to
20Hz.
Frequency Deviation Setting
Frequency deviation represents the difference between frequency of the FM modulated waveform and the carrier
frequency. Settable range of FM frequency deviation is from 1μHz to the maximum of current carrier wave frequency,
and the default value is 1kHz. If need to change, press Parameter→Frequency Deviation in turn.
Frequency deviation is less than carrier wave frequency. If frequency deviation value is set higher than carrier
wave frequency, the device will automatically set the offset value to the carrier frequency’s maximum allowable
frequency.
Sum of frequency deviation and carrier wave frequency is less than the allowed maximal frequency of current
carrier wave. If the frequency deviation value is set to an invalid value, the device will automatically set the
offset value to the carrier frequency’s maximum allowable frequency.
26
Comprehensive Example:
Make the instrument work in frequency modulation (FM) mode, then set a sine wave with 2kHz from the internal of
the instrument as a modulation signal and a square wave with frequency of 10kHz and amplitude of 100mVpp as a

Appendix D Maintenance and Cleaning
Cleaning
•
Clean the meter with a clean, soft cloth.
•
Do not use any chemicals, abrasives or solvents that could damage the meter.
•
Take great care when cleaning the screen to avoid scratches and use only a damp cloth to remove dirt.
Warning: please confirm that the instrument is completely dry before powering on to prevent electrical short circuit
and even personal injury due to moisture.
