TDS200/1000/2000 Series Oscilloscope Programmer Manual
Y specifies a normal waveform where one ASCII or binary data point
is transmitted for each point in the waveform record.
For Y format, the time (absolute coordinate) of a point, relative to the
trigger, can be calculated using the following formula. N ranges from
0 to 2499.
X
n
= XZEro + XINcr (n - PT_OFf)
For Y format, the magnitude (usually voltage, relative to ground)
(absolute coordinate) of a point can be calculated:
Y
n
= YZEro + YMUIty (y
n
- YOFf)
ENV specifies that the oscilloscope transmit the waveform as
minimum and maximum point pairs. Peak detect waveforms use
ENV format. Peak Detect mode specifies a maximum of 1250
(minimum, maximum) pairs, with the time between pairs being
2*XINcr.
The magnitudes and times of ENV format waveform points can be
calculated using the same formulas used for Y format, as long as you
recognize that the points consist of (minimum, maximum) pairs,
where each pair was collected over a time period of 2*XINcr.
Thus, the samples for n=0 (a minimum) and n=1 (a maximum), the
first (minimum, maximum) pair, were collected over a time interval
of width 2*XINcr, that began at the time found by setting n to zero
in the formula. The next pair were collected over the interval that
began at the time found by setting n to 2 in the formula, and so on.
WFMPre:PT_Fmt Y
sets the waveform data point format to Y.
WFMPre:PT_Fmt?
returns either Y or ENV
