scan.measurecount
Attribute
Set or query the measure count value for scanning.
Usage
To read the count:
count = scan.measurecount
count: Present measure count value being used
To write the count:
scan.measurecount = count
count: Value to set the measure count. Valid range: 1 to 450000.
Remarks
This attribute sets the measure count in the trigger model. During a scan, the Series
3700 will iterate through the sequence event detector and measure action of the
trigger model this many times. After performing this count iterations, the Series 3700
will return to check the scan count.
The reset value for this attribute is 1.
Details
The measure count value:
is the number of measurements to take per scan step
must be set before a scan is started
applies to all scan steps in the list (the ones already existing in the list as well as
the new ones to be added before the scan is started)
Example
To set the measure count to 5:
scan.measurecount = 5
scan.mode
Attribute
Use to set or query the scan mode value.
Usage
To read the scan mode value:
init = scan.mode
init: The present scan mode setting
To write the scan mode value:
scan.mode = init
init: The desired value of set the scan mode setting. Use one of the following:
scan.MODE_OPEN_ALL or 0: indicates if an openall on all slots should be
performed before a scan starts (default setting).
scan.MODE_OPEN_SELECTIVE or 1: indicates that an intelligent open takes
place (see remarks)
scan.MODE_FIXED_ABR or 2: this setting is equivalent to
MODE_OPEN_SELECTIVE plus the following:
-close all required backplane relays before start of scan
-does not open or close these backplane relays during the scan
-does not open these backplane relays at the end of scan
