Example Language
Small examples are given at various
places in the text. These examples are not
in BASIC or C, nor are they written for
any specific controller. They only contain
the characters you should send to the
counter and the responses that you should
read with the controller.
Example:
SEND→
MEAS:FREQ?
This means that you should program the
controller so that it addresses the counter
and outputs this string on the GPIB.
READ←

This means that you should program the
controller so that it can receive this data
from the GPIB, then address the counter
and read the data.
