Control Lines
After a power reset all DUT control lines are initially configured to a logic high state or
connected to Pin 13, refer to
. To reset all control lines to logic
high, without having to reset the power switch on the test set, make the following
PNA entry:
Front panel PNA Interface Control Mode line entry =
112.0 > OK.
Always determine which control lines you want set to a logic zero, the other
remaining lines will automatically be set to a logic high. Note the <data> value of
these lines and calculate the SUM of their <data> values.
Listed are two examples to illustrate this concept. Refer to
shown with all lines = logic high.
To change lines 1 & 8 to equal logic Low, all others logic high.
1. Line 1 (<address> = 112 and <data> = 1)
2. Line 8 (<address> = 112 and <data> = 128)
3. The SUM of the <data> values = 129
4. Front panel PNA Interface Control Mode line entry = 112.129 > OK.
Example 2
From Example 1 to only change Lines 2 & 3 to equal logic low, all others logic high.
1. Line 2 (<address> = 112 and <data> = 2)
2. Line 3 (<address> = 112 and <data> = 4)
3. The SUM of the <data> values = 6
4. Front panel PNA Interface Control Mode line entry = 112.6 > OK.
Since all control lines have the same <address>, only one "<address>.<data>"
command line is needed to control all 8 lines.
