Keithley S530 User Manual

S530/S540 KTE Linear Parametric Test Library (LPTLib) User's Manual Section 3:
LPTLib command reference
S530-900-01 Rev. E / September 2017 3-25
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);
