MODULATION MODULATION The AFG-3000 Series Arbitrary Function Generators are able to produce AM, FM, FSK and PWM modulated waveforms. Depending on the type of waveform produced, different modulation parameters can be set. Only one modulation mode can be active at any one time. The function generator also will not allow sweep or burst mode to be used with AM/FM. Activating a modulation mode will turn the previous modulation mode off.

MODULATION Amplitude Modulation (AM) An AM waveform is produced from a carrier waveform and a modulating waveform. The amplitude of the modulated carrier waveform depends on the amplitude of the modulating waveform. The AFG-3000 function generator can set the carrier frequency, amplitude and offset as well as internal or external modulation sources.
PAGE 68
AFG-3000 Series User Manual Selecting AM Modulation Panel Operation 1. Press the MOD key. 2. Press F1 (AM). AM Carrier Shape Background Select a Standard Carrier Shape The shape function selects the AM carrier waveform shape. Sine, square, triangle, ramp, pulse or arbitrary waveforms can be used as the carrier shape. The default waveform shape is set to sine. Noise is not available as a carrier shape. Before the carrier shape can be selected, choose AM modulation mode, see page 28 or 70. 1.
PAGE 69
MODULATION Select an Arbitrary Waveform Carrier Shape. Range 3. See the Arbitrary waveform Page 35 quick guide or chapter to Page 137 use an arbitrary waveform. AM Carrier Shape sine, square, triangle, upramp, dnramp, arbitrary waveform Carrier Frequency The maximum carrier frequency depends on the carrier shape selected. The default carrier frequency for all carrier shapes is 1kHz. Panel Operation 1. With a carrier waveform, press the FREQ/Rate key. 2.
PAGE 70
AFG-3000 Series User Manual Modulating Wave Shape The function generator can accept internal as well as external sources.

PAGE 72
AFG-3000 Series User Manual Modulation Depth Modulation depth is the ratio (as a percentage) of the unmodulated carrier amplitude and the minimum amplitude deviation of the modulated waveform. In other words, modulation depth is the maximum amplitude of the modulated waveform compared to the carrier waveform as a percentage. Panel Operation 1. Press the MOD key. 2. Press F1 (AM). 3. Press F2 (Depth). 4. The AM Depth parameter will become highlighted in the waveform display area. 5.

MODULATION 6. Press F1 (%) to choose % units. Range Note Depth 0%~120% Default depth 100% When the modulation depth is greater than 100%, the output cannot exceed ±5VPeak (10kΩ load). If an external modulation source is selected, modulation depth is limited to ± 5V from the MOD INPUT terminal on the rear panel. For example, if modulation depth is set to 100%, then the maximum amplitude is +5V, and the minimum amplitude is -5V.
PAGE 74

MODULATION Frequency Modulation (FM) A FM waveform is produced from a carrier waveform and a modulating waveform. The instantaneous frequency of the carrier waveform varies with the magnitude of the modulating waveform. When using the AFG-3000 function generator, only one type of modulated waveform can be created at any one time.

AFG-3000 Series User Manual Apply Commands The APPLy command has 8 different types of outputs (Sine, Square, Ramp, Pulse, Noise, Triangle, DC, User). The command is the quickest, easiest way to output waveforms remotely. Frequency, amplitude and offset can be specified for each function. As only basic parameters can be set with the Apply command, other parameters use the instrument default values. The Apply command will set the trigger source to immediate and disable burst, modulation and sweep modes.
PAGE 205
REMOTE INTERFACE Output Amplitude When setting the amplitude, MINimum, MAXimum and DEFault can be used. The range depends on the function being used and the output termination (50Ω or high impedance). The default amplitude for all functions is 100 mVpp (50Ω). If the amplitude has been set and the output termination is changed from 50Ω to high impedance, the amplitude will double. Changing the output termination from high impedance to 50Ω will half the amplitude.
PAGE 206
AFG-3000 Series User Manual The offset is also determined by the output termination (50Ω or high impedance). If the offset has been set and the output termination has changed from 50Ω to high impedance, the offset will double. Changing the output termination from high impedance to 50Ω will half the offset. SOURce[1]:APPLy:SINusoid Description Syntax Parameter Example Source Specific Command Outputs a sine wave from the selected channel when the command has executed.

REMOTE INTERFACE -222 Data out of range;frequency; value clipped to ... Example: If the frequency was set to a value out of range, it is automatically set to an upper or lower limit. -222 Data out of range;user frequency; value clipped to upper limit Example: If the frequency is set to a value out of range for an arbitrary waveform using, SOURce[1]: APPL: USER or SOURce[1]: FUNC:USER, it is automatically set to the upper limit.
~~PAGE 284~~
AFG-3000 Series User Manual -222 Data out of range; burst period limited by length of burst; value clipped to upper limit Example: The burst period must be greater than burst count divided by the frequency + 200 ns. The burst period is adjusted to satisfy these conditions. burst period > 200 ns + (burst count/burst frequency).

REMOTE INTERFACE -222 Data out of range;marker confined to sweep span; value clipped to ... Example: The marker frequency is set to a value outside the start or stop frequencies. The marker frequency is automatically adjusted to either the start or stop frequency (whichever is closer to the set value). -222 Data out of range;FM deviation; value clipped to ... Example: The frequency deviation is outside of range. The deviation is automatically adjusted to an upper or lower limit, depending on the frequency.

REMOTE INTERFACE Query Errors -410 Query INTERRUPTED Indicates that a command was received but the data in the output buffer from a previous command was lost. -420 Query UNTERMINATED The function generator is ready to return data, however there was no data in the output buffer. For example: Using the APPLy command. -430 Query DEADLOCKED Indicates that a command generates more data than the output buffer can receive and the input buffer is full.

REMOTE INTERFACE SCPI Status Registers The status registers are used to record and determine the status of the function generator. The function generator has a number of register groups: Questionable Status Registers Standard Event Status Registers Status Byte Register As well as the output and error queues. Each register group is divided into three types of registers: condition registers, event registers and enable registers.

REMOTE INTERFACE The Status Byte Register Description The Status Byte register consolidates the status events of all the status registers. The Status Byte register can be read with the *STB? query or a serial poll and can be cleared with the *CLS command. Clearing the events in any of the status registers will clear the corresponding bit in the Status Byte register. Notes The Status byte enable register is cleared when the *SRE 0 command is used.
~~PAGE 294~~
AFG-3000 Series User Manual Standard Event The Event Status bit is set if an “enabled” event in the Standard Event Status Event Register has occurred. Master Summary/ Service Request bit The Master Summary Status is used with the *STB? query. When the *STB? query is read the MSS bit is not cleared. The Request Service bit is cleared when it is polled during a serial poll. Output Queue Description The Output queue stores output messages in a FIFO buffer until read.
