-151Invalid string data

-151Invalid string data

An invalid character string was received. Check to see if you have enclosed the character string in single or double quotes and that the string contains valid ASCII characters.

-158String data not allowed

A character string was received but is not allowed for the command. Check the list of parameters to verify that you have used a valid parameter type. Example: BMOD:NCYC 'TEN'

-161Invalid block data

Applies only to the DATA:DAC VOLATILE command. For a definite- length block, the number of bytes of data sent does not match the number of bytes that you specified in the block header. For an indefinite-length block, an EOI (End-or-Identify) was received without an accompanying <new line> character.

-168Block data not allowed

Block data was received but is not allowed for the command. Check to see if you have sent the correct data type with the command.

-170 to -178Expression errors

The function generator does not accept mathematical expressions.

-211Trigger ignored

A Group Execute Trigger (GET) or *TRG was received but the trigger was ignored. Make sure that you have selected the correct trigger source.

-221Settings conflict; amplitude has been adjusted

The requested output amplitude is not valid. The output amplitude is automatically adjusted to be compatible with the present configuration. This error will be generated in the following instances:

The output amplitude is automatically adjusted if you select a function whose maximum amplitude is less than that of the currently active function. This conflict may arise when the output units are Vrms or dBm due to the differences in crest factor.

If the specified amplitude is not valid, the function generator will automatically adjust it to the maximum value allowed with the present offset voltage. 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; cannot adjust phase in present configuration Option 001 Phase-Lock Only. The phase cannot be adjusted real-time if an arbitrary waveform is selected, a modulation mode (other that burst)

is enabled, or if burst is enabled with a burst count other than infinity.
