Code examples
Example 1
The following code segment sets CVU1 to perform a system mode sweep of DC voltage from 5 V to
10 V in 1 V steps. After the test completes, the Z, DCV, F, timestamps, and status values are queried.
The operation mode is then changed to perform a list sweep of DC voltage (2 V, 4 V, 3 V, 5 V, 7 V)
and the test is run again with all other test conditions as previous.
// Soft Reset card
send(addr, ":CVU:RESET", &status);
// Set CVU to System Mode
send(addr, ":CVU:MODE 1", &status);
// Set measurement model to Z, theta
send(addr, ":CVU:MODEL 0", &status);
// Set speed to Normal
send(addr, ":CVU:SPEED 1", &status);
// Set AC drive level to 45 mV at 7MHz
send(addr, ":CVU:ACV 0.045", &status);
send(addr, ":CVU:FREQ 7E+6", &status);
// Set DC bias level to 10 V
send(addr, ":CVU:DCV 10", &status);
