Page 262: Apply Commands
REMOTE INTERFACE Apply Commands The APPLy command has 8 different types of outputs (Sine, Square, Ramp, Pulse, Noise, Triangle, Harmonic, 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.
Page 263 AFG-3021/3022/3031/3032 User Manual When setting the amplitude, MINimum, Output MAXimum and DEFault can be used.

For more information regarding the error queue, see page 404. Command Error Codes -101 Invalid character An invalid character was used in the command string.
Page 386 REMOTE INTERFACE -112 Program mnemonic too long A command header contains more than 12 characters: OUTP:SYNCHRONIZATION ON -113 Undefined header An undefined header was encountered. The header is syntactically correct. Example: the header contains a character mistake. SOUR1:AMM:DEPT MIN -123 Exponent too large Numeric exponent exceeds 32,000.

Example: The number of bytes sent with the DATA:DAC command doesn’t correlate to the number of bytes specified in the block header.
Page 388 REMOTE INTERFACE -221 Settings conflict; infinite burst changed trigger source to MANual Example: The trigger source is changed to immediate from manual when infinite burst mode is selected. -221 Settings conflict; burst period increased to fit entire burst Example: The function generator automatically increases the burst period to allow for the burst count or frequency.
Page 389 AFG-3021/3022/3031/3032 User Manual -221 Settings conflict;frequency made compatible with burst mode Example: When the function is changed to burst, the output frequency is automatically adjusted if over range. -221 Settings conflict;not able to modulate this function Example: A modulated waveform cannot be generated with noise or pulse waveforms.
Page 390 REMOTE INTERFACE -221 Settings conflict;amplitude changed due to function Example: The amplitude (VRM / dBm) has been adjusted to suit the selected function. For the AFG- 30XX, a typical square wave has a much higher amplitude (5V Vrms) compared to a sine wave (~3.54) due to crest factor.
Page 391 AFG-3021/3022/3031/3032 User Manual -221 Settings conflict;high level changed due to low level Example: The high level value was set too low. The high level is set 1 mV greater than the low level. -222 Data out of range;value clipped to upper limit Example: The parameter was set out of range.
