N - Number of Cycles
TYPE Port Command
SYNTAX Nval Specifies the number of cycles that will be output when a DAC port is in the
waveform mode, where val is a value between 0 and 65535; val = 0 will
cause the DAC port to output the buffer values continuously.
N? Returns the number of cycles specified for use in the Waveform mode.
DESCRIPTION
The Number of Cycles command specifies how many times the values in a specified buffer will be output. For
example, if it is desired to output a waveform 3 times, the number of cycles would be 3.
Note: The default value for n is 1, or 1 cycle.
EXAMPLE
PRINT#1,"CLEAR09" Line 1: Reset the DAC488.
PRINT#1,"OUTPUT09;C3 P1 F0,2
G1 N30 L0 I2000 X"
Line 2: Select Waveform Control mode, select port 1, define a buffer
with the first location=0 and a size=2, enable port 1 to trigger on
GET, set number of cycles=30, set location pointer to 0 (first
location), set time interval between point to 2 seconds.
PRINT#1,"TRIGGER" Line 3: Trigger the DAC488. The DAC488 will output the waveform
30 times then halt.
