With this VI you can set up the clock. All commands for controlling the clock are grouped into this vi to obtain a familiar functionality. The clock is configured using three choices and an optional control for setting the software clock period. The possible clock types are [10 MHz, 1 MHz, software clock, external clock]. Possible modes are [continuous, burst, burst and invert]. Possible triggering sources are [internally, externally]. In addition if the software clock was chosen, also its period will be set, otherwise this control will be ignored. Valid values for the software clock period are [1…35] ms with 1 ms resolution. It also sets the general time out of the VISA session depending on the clock type. For the 10 MHz clock the maximum time that can be generated is about 40261 ms for the 1 MHz clock this is about 402608 ms. For the software clock this ranges from 1 to 35 times 402608129 ms. These values are set as general time out when configuring the clock. For the external clock a value of 402608129 ms is set, corresponding to a 1 kHz or higher clock, if a clock lower than 1 kHz is used you should set the time out manually after calling this VI with an attribute node.
