niScope Cal Measure RIS Distribution
Calls niScope Read Waveform 2,000 times to take an acquisition from the specified channel and retrieve the initial X value, which includes the time-to-digital conversion. The time-to-digital conversion should be a uniform distribution between two sample points, because triggers should occur randomly. To test this distribution, the distribution of initial X values is created. The percentage of triggers in the smallest bin of this distribution is returned for comparison to a specification to determine if RIS is operating correctly.

instrument handle identifies a particular instrument session. | ||||||
 |
max time (ms) is the maximum time to allow for each acquisition. | ||||||
 |
channel name is the channel to calibrate. For more information, refer to Channel String Syntax. | ||||||
|
distribution size is the number of bins in the initial x distribution. | ||||||
 |
error in describes error conditions that occur before this VI runs. The default input of this cluster is no error. If an error already occurred, this VI returns the value of error in in error out. The VI runs normally only if no incoming error exists. Otherwise, the VI passes the error in value to error out. The error in cluster contains the following parameters:
| ||||||
 |
instrument handle out has the same value as the instrument handle. | ||||||
 |
min bin percent is the percent of triggers in the minimum bin (0–100.0). | ||||||
 |
distribution array (waveform array) is the returned distribution of trigger times. | ||||||
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
