Arbitrary Waveforms

There are three built-in Arbitrary waveforms offered. The U2761A supports the Arbitrary waveform up to 65536 (64K) data points. You can create an Arbitrary waveform using the soft front panel as described in the following. For further information, please refer to the Agilent Measurement Manager help file.

To Create and Store an Arbitrary Waveform

This section provides you an example on the procedure to create and store an Arbitrary waveform using the soft front panel. To create an Arbitrary waveform remotely, refer to the Agilent U2761A USB Modular Function/Waveform Generator Programmer’s Reference. You will create and store the Ramp waveform shown below as an example.

Amplitude = 2 Vpp, Period = 10 ms
