Making the Waveform (Time Domain) Measurement

❏Auto - The data packing value most appropriate for current instrument settings is selected automatically.

❏Short (16 bit) - Select this to pack data every 16 bits.

❏Medium (24 bit) - Select this to pack data every 24 bits.

❏Long (32 bit) - Select this to pack data every 32 bits.

—ADC Dither - Allows you to toggle the ADC dither function between On and Off. The default setting is Off. If set to On, the ADC dither refers to the introduction of noise to the digitized steps of the analog-to-digital converter, and results in better amplitude linearity and resolution in low level signals. However, it also results in reduced dynamic range by approximately 3 dB.

—Decimation - Allows you to toggle the decimation function between On and Off, and to set the decimation value. Decimation allows longer acquisition times for a given bandwidth by eliminating data points. Long time captures can be limited by the instrument data acquisition memory. Decimation numbers 1 to 4 describe the factor by which the number of points are reduced. The default setting is 1, which results in no data point reduction.
