Agilent Technologies E1441A user service Settings conflict; frequency has been adjusted

-221Settings conflict; duty cycle has been adjusted

The requested duty cycle is not valid. For output frequencies above 5 MHz, the duty cycle is limited to values between 40% and 60% (below 5 MHz, the range is 20% to 80%). The duty cycle is automatically adjusted if you select a frequency that is not valid with the present duty cycle percentage. For example, if you set the duty cycle to 70% and then change the frequency to 8 MHz, the function generator will automatically adjust the duty cycle to 60% (the upper limit for this frequency).

-221Settings conflict; fm deviation has been adjusted

The requested FM peak frequency deviation is not valid. The sum of the carrier frequency and peak frequency deviation must be less than or equal to the maximum frequency for the selected function plus 100 kHz (15.1 MHz for sine and square, 200 kHz for triangle and ramp, and 5.1 MHz for arbitrary waveforms). If you attempt to set the deviation to a value that is not valid, the function generator will automatically adjust the deviation to the maximum value allowed with the present carrier frequency.

-221Settings conflict; frequency has been adjusted

The requested output (or carrier) frequency is not valid. The output frequency is automatically adjusted if you select a function whose maximum frequency is less than that of the currently active function. For example, if you output a 1 MHz sine wave and then change the function to triangle wave, the function generator will adjust the output to 100 kHz (the upper limit for triangle waves).

-221Settings conflict; fsk frequency has been adjusted

The requested FSK “hop” frequency is not valid. The FSK frequency is automatically adjusted if you select a function whose maximum frequency is less than that of the currently active function. For example, if you set the FSK frequency to 1 MHz in the sine function and then change the function to triangle wave, the function generator will adjust the frequency to 100 kHz (the upper limit for triangle waves).

-221Settings conflict; offset has been adjusted

The requested offset voltage is not valid with the present output amplitude. The offset is automatically adjusted to the maximum value allowed with the present output amplitude. The output amplitude (in Vpp) and the dc offset voltage must obey the following restrictions. (Vmax is either 10 volts for a high impedance termination or 5 volts for a 50 ohm termination.)

-221Settings conflict; start frequency has been adjusted

The requested start frequency is not valid. The start frequency is automatically adjusted if you select a function whose maximum frequency is less than that of the currently active function. For example, if you set the start frequency to 200 kHz in the sine wave function and then change the function to triangle wave, the function generator will adjust the output to 100 kHz (the upper limit for triangle waves).
