WARNING
Do not apply voltages that exceed the rated isolation voltage. Doing so may result in
insulation breakdown and risk of electrical shock. Damage to the instrument may also
result.
■ Oscillator output connector (OSC)
The oscillator output (
OSC
) is electrically isolated from the instrument enclosure. The analyzer inputs
(
CH1
and
CH2
) are also both isolated.
Maximum output voltage : ±10 V (AC + DC)
Maximum output current : ±100 mA
Output impedance: : 50 Ω ±2%
Isolation voltage : 600 V CAT II or 300 V CAT III (BNC ground to enclosure)
Connectors : Front panel, insulated BNC connector

WARNING
Do not connect the instrument to circuits that exceed MEASUREMENT CATEGORY
II/600 V or MEASUREMENT CATEGORY III/300 V. Doing so may result in insulation
breakdown and risk of electrical shock or damage to the equipment.
Using a BNC connector that has exposed metal parts rather than the insulated BNC cable that is provided
with this instrument may expose the user to high voltages and the risk of electrical shock. The coaxial
BNC cable that is provided with this instrument is designed for safety. When dealing with dangerously
high voltages that exceed 30 Vrms or 42Vpk, be certain to use the provided cable.
The AC signal is output from the
OSC
connector on the front panel. The DC bias is output from either
the front panel
OSC
connector or the rear panel
DC BIAS OUTPUT
connector (simultaneous output
from both connectors is not possible). The connector for output of the DC bias can be selected from the
menu.
