Functional Specifications
Break down voltage test (BDV) mode
Test overview Tests the impulse while gradually increasing the voltage applied to the workpiece to
examine the discharge judgments.
Waveform surface area judgments, discharge judgments, LC and RC values area
judgments, peak voltage value fluctuations, and vibration frequency fluctuations are
used in discharge judgments.
Applied voltage settings Sets the values of the start voltage, max. voltage, and voltage rise width
Start voltage
Settings range:
ST4030: 100 V to 3300 V (resolution: 10 V)
ST4030A: 100 V to 4200 V (resolution: 10 V)
Max. voltage Settings range:
ST4030: 100 V to 3300 V (resolution: 10 V)
ST4030A: 100 V to 4200 V (resolution: 10 V)
Voltage rise width Settings range:
ST4030: 10 V to 3200 V (resolution: 10 V)
ST4030A: 10 V to 4100 V (resolution: 10 V)
Maximum number of
steps
32 steps
Number of applied pulses Sets the number of
application pulses and
the number of degaussing
pulses.
Degaussing pulse: Applied using the set number of
continuous pulses during BDV test startup
Application pulse: Applied using the set number of
continuous pulses for each step
Number of pulses: 3 to 32
Number of degaussing pulses: 0 to 10
Sets the pulse application
interval
Sets the minimum time of the pulse application interval
when the settings for the number of application pulses
and degaussing pulses is 2 or more.
Setting range: 0.050 s to 1.000 s (resolution: 0.001 s)
Sampling frequency
Sets the voltage sampling frequency
Setting range: 10 MHz, 20 MHz, 50 MHz, 100 MHz, 200 MHz
Number of sampling data Sets the number of sampling data so that the required waveform length is imported.
Settings range: 1001 to 8001 points (1000 points step)
