In the programming for the U2701A and U2702A Modular Oscilloscopes, you sometimes get a different waveform compared to the one on the Measurement Manager (AMM) software because the Vertical Range and TimePerRecord set in the programming may not be correct.

You are required to fill up the Vertical Range and TimePerRecord value based on the vertical and horizontal settings in the AMM software Front Panel Display.

TimePerRecord is the time in seconds that corresponds to the record length of the single acquisition. It is equivalent to the time/div x 10 div at the scope setting. For example, to capture 2 complete sine waves at 1kHz, set the TimePerRecord to 2ms.

Vertical Range is the absolute value of the input range that the oscilloscope can acquire for the channel. The units are volts. It is equivalent to the volt/div x 8 div at the scope setting. For example, to acquire a sine wave spanning -5.0 to 5.0 volts, set Vertical Range to 16 volts.
