delcon
This command removes specific matrix connections.
Usage
int delcon(int
exist_connect
, [int
exist_connectn
, [...]] 0);
exist_connect
A pin number or an instrument terminal ID
exist_connectn
A pin number or an instrument terminal ID
Details
All connections to each terminal or pin listed are disconnected. Before disconnecting the pins or
terminals, the
delcon
command clears all active sources by calling the
devclr
command.
If GND is included in the list, all ground connections are removed. Source-measure unit (SMU) lows
are hard-wired to ground.
A programmer can run a series of tests in a single test sequence using the
addcon
and
delcon
commands together without breaking existing connections. Only the required terminal and pin
changes are made before the next sourcing and measuring operations.
Example
double i1, i2;
conpin(3, 4, GND, 0);
conpin(1, SMU1, 0);
conpin(2, SMU2, 0);
forcev(SMU1, 1.0);
forcei(SMU2, 0.001);
measi(SMU1, &i1);
delcon(GND, 4, 0); /* remove SMU2 from the circuit */
forcev(SMU1, 1.0); /* because delcon cleared sources */
measi(SMU1, &i2);
