Using Commands That Retrieve Test Results
No commands are available that allow you to directly retrieve the overall test result that
combine the test results for all channels.
Using the Status Register
Each of the condition register and event register under the questionable status event
register provides bit 10, from which you can obtain the overall test result (0:Pass, 1:Fail).
The condition register's bit 10 is set to 0 after the event registers are cleared by *CLS
command on page 196. Upon completion of measurement, this bit is set to 1 if the overall
test result that combines the results for all channels
*1
is “fail”.
If the positive transition filter’s bit 10 sets to 1 (preset value), the event register's bit 10 is
set to 1 when the condition register's bit 10 changes from 0 to 1.
To retrieve the condition register and event register under the questionable status register,
use the following command:

*1.This is when the registers are set as preset values. You can configure the enable regis-
ters and transition filters under the questionable limit status register so that the con-
dition register's bit 10 reflects the result that combines the results for a limited set of
channels, rather than for all the channels.
