Agilent B1500A/B1505A Programming Guide, Edition 11 4-235
Command Reference
WV
3: Linear sweep (double stair, start to stop to start.)
4: Log sweep (double stair, start to stop to start.)
range : Ranging type for staircase sweep voltage output. Integer expression.
See Table 4-4 on page 4-21.
The B1500 usually uses the minimum range that covers both start and
stop values to force the staircase sweep voltage. However, if you set
Pcomp and if the following formulas are true, the B1500 uses the
minimum range that covers the output value, and changes the output
range dynamically (20 V range or above). Range changing may cause
0 V output in a moment. For the limited auto ranging, the instrument
never uses the range less than the specified range.
Icomp > maximum current for the output range
Pcomp/output voltage > maximum current for the output range
start, stop : Start or stop voltage (in V). Numeric expression. See Table 4-7 on page
4-24, Table 4-9 on page 4-26, Table 4-12 on page 4-27, or Table 4-15
on page 4-28 for each measurement resource type. start and stop must
have the same polarity for log sweep.
step : Number of steps for staircase sweep. Numeric expression. 1 to 10001.
Icomp : Current compliance (in A). Numeric expression. See Table 4-7 on page
4-24, Table 4-9 on page 4-26, Table 4-12 on page 4-27, or Table 4-15
on page 4-28 for each measurement resource type. If you do not set
Icomp, the previous value is used.
Compliance polarity is automatically set to the same polarity as the
output value, regardless of the specified Icomp. If the output value is 0,
the compliance polarity is positive.
If you set Pcomp, the maximum Icomp value for the measurement
resource is allowed, regardless of the output range setting.
Pcomp : Power compliance (in W). Numeric expression. Resolution: 0.001 W. If
the Pcomp value is not entered, the power compliance is not set. This
parameter is not available for HVSMU.
0.001 to 2 for MPSMU/HRSMU, 0.001 to 20 for HPSMU, 0.001 to 40
for HCSMU, 0.001 to 80 for dual HCSMU, 0.001 to 3 for MCSMU,
0.001 to 100 for UHVU
