pulse_limits
This command sets measured voltage and current thresholds at the DUT and sets the power threshold for each
channel.
Usage
int pulse_limits(int
instr_id
, int
chan
, double
V_Limit
, double
I_Limit
, double
Power_Limit
);
instr_id
The instrument identification code: PMU1, PMU2, and so on
chan
Channel number of the pulse card:
1
or
2
V_Limit
Measured voltage (V) threshold at the DUT
I_Limit
Measured current (A) threshold at the DUT
Power_Limit
Power (W) threshold for the channel (Power = V
meas
x I
meas
)
Pulsers
4225-PMU
Pulse mode
Standard
Details
This feature differs from a SMU compliance setting in that threshold checking is done after each burst
of pulses, using the spot mean values to compare to the specified thresholds. The thresholds are
checked against all enabled measurements for the channel. If a threshold is reached or exceeded,
the present sweep is stopped and testing continues with any subsequent sweeps.
This feature does not prevent the set thresholds from being reached or exceeded. After detecting a
threshold breach, it aborts the sweep.
Maximum power for each PMU source range:
High-speed voltage source (10 V) range: Maximum power = 5 V x 0.1 A = 0.5 W
High-voltage source (40 V) range: Maximum power = 20 V x 0.4 A = 8 W
Example
pulse_limits(PMU1, 1, 42, 1, 10);
This example sets thresholds for channel 1 of the PMU, where:
•
instr_id
= PMU1
•
chan
= Channel 1
•
V_Limit
= 42 V
•
I_Limit
= 1 A
•
Power_Limit
= 10 W
