*acquisition types NORMAL, PEAK, or AVERAGE.

*/

*for an acquisition. The parameter determines the percentage

*of time buckets needed to be "full" before an acquisition is

*considered to be complete.

*/

/* DIGITIZE - Used to acquire the waveform data for transfer over

*the interface. Sending this command causes an acquisition to

*take place with the resulting data being placed in the buffer.

*/

/* NOTE! The use of the DIGITIZE command is highly recommended

*as it will ensure that sufficient data is available for

*measurement. Keep in mind when the oscilloscope is running,
