Tracer Test
Meas. Time This field is used to set the measurement time for a sweep step.
Meas. Delay Time This field is used to set the measurement delay time (from the beginning of pulse
period to the beginning of measurement) for a pulse step. This entry field appears if
a pulse output channel exists.
2 s to Pulse period - Measurement time - 2 ms, 2 s resolution
Measurement delay time = 0 (AUTO) sets the optimum value automatically so that
the measurement is completed when the transition from peak to base is started by
the pulse output channel which starts the transition at first.
Step Time This field is used to set the output time for a sweep step. 500 s to 5 s, 100 s step.
Pulse Period This field is used to set the pulse period. This entry field appears instead of the Step
Time entry field if a pulse output channel exists.
NOTE About measurement time and measurement error
In the tracer test mode, measurement is always performed by using the following
settings.
• A/D converter: HS ADC (high speed A/D converter)
• Measurement ranging mode: compliance range, fixed
• Effective current measurement range: all for staircase sweep output, 10 nA and
greater for bias output or pulse output
• Measurement time: absolute value entered into the Meas. Time field
You may find difference between the results measured in the tracer test mode and in
the other test mode. This is caused by the differences of setting values for the above
items. The above settings will reduce measurement time and increase measurement
error compared with when using HR ADC (high speed A/D converter) and auto
ranging in the other test mode.
NOTE Drag the region of VAR1, VAR2, and CONST
Mouse drag operation will scroll this region when it cannot display all setup
parameters.
