Now the curve storage needs to be set up:
NC Clear and reset curve buffer
CBD 19 Stores X channel output, Y channel output and sensitivity
(i.e. bits 0, 1 and 4)
LEN 1000 Number of points = 100 Hz × 10 seconds
STR 10000 Store a point every 10 ms (10,000 µs)
The data is acquired by issuing:
TD Acquires data
As the acquisition is running, the M command reports the status of the curve
acquisition. Once this indicates the acquisition is complete (i.e. parameter 1 = 0,
parameter 2 = 1), the acquired data may be transferred to the computer using:
DC. 0 Transfers X channel output values in floating point mode.
DC. 1 Transfers Y channel output values in floating point mode.
The input routine of the program must be prepared to read and store 1000 responses
to each of these commands.
