ZA 57630
When using HV DC bias ±40 V
Maximum driving current
: 60 mArms (depends on the measurement range, frequency etc.)
Output impedance : 50 Ω
(When HV DC bias is used, approximately 1 kΩ at approximately
100 Hz or less.)
■ Measurement connectors when power is off
The measurement connectors are connected to the internal circuits even when the power is off.
！
CAUTION
・
Do not apply a large external signal to the measurement connectors. Even when the power is
off, do not apply an external signal. There is a risk of damage to this instrument.
・
Do not connect a charged capacitor. If there is a possibility that the DUT may be charged,
discharge the DUT sufficiently before connecting it. If the DUT is discharged to the
measurement connectors, this instrument may be damaged.
