Agilent Technologies L4400 manual Waveform Mode

L4451A 4-Channel Isolated D/A Converter with Waveform Memory 9

Waveform Mode

Example: Downloading a waveform to memory and outputting waveform from DACs The following command segment downloads a 1000- point sine waveform to memory and outputs the waveform from DAC channels 1 and 2. The trace name is TEST_SINE.

TRACe:FUNCtion 1,SINusoid, TEST_SINE, 1000 SOURce:FUNCtion:TRACe TEST_SINE,(@1001,1002) OUTPut:STATe ON,(@1001,1002) SOURe:FUNCtion:ENABle ON,(@1001,1002)

Example: Downloading trace points to memory and outputting waveform from DACs

The following command segment downloads seven trace points to memory and output the waveform from DAC channels 1 and 2. The trace name is "NEG_RAMP".

TRACe:DATA 1,NEG_RAMP, 1, .67, .33, 0, -.33, -.67, -1 SOURce:FUNCtion:TRACe NEG_RAMP,(@1001,1002) OUTPut:STATe ON,(@1001,1002)

SOURe:FUNCtion:ENABle ON,(@1001,1002)

Example: Setting the amplitude of a waveform for offset and gain

The following commands set the offset to 5.25 and the gain to 1.5 on DAC channels 1 and 2.

SOURce:FUNCtion:VOLTage:OFFSet 5.25,(@1001,1002)

SOURce:FUNCtion:VOLTage:GAIN 1.5,(@1001,1002)

Example: Setting cycle count for a waveform The following command segments turn off the trace output mode on DAC channels 1 and 2, set the cycle count to 100, then turn the trace output mode back on.

SOURce:FUNCtion:ENABle OFF,(@1001,1002)

SOURce:FUNCtion:TRACe:NCYCles 100,(@1001,1002) SOURce:FUNCtion:ENABle ON,(@1001,1002)

Example: Deleting a waveform The following command deletes the trace named TEST_WFORM from the instrument.

TRACe:DELete 1,TEST_WFORM
