Differential Probe Capable of Wide-Band,

High-Voltage Floating Measurements

Allows you to use a single-end input oscilloscope for wide-band differential input measurements

Waveform observed on oscilloscope

Oscilloscope input amplifiers are normally single-ended.
They do not provide accurate measurements when used
in combination with a 10:1 passive probe for measuring
the gate-to-source voltage of a switching power supply,
or potential difference with a common mode voltage in
elements such as Insulated Gate Bipolar Transistors
(IGBTs). Furthermore, there is a risk that current will enter
through the oscilloscope’s ground line and damage the
oscilloscope.

Signals floating from ground

With increases in the speed of measured signals in recent
years, it has become necessary to make floating
measurements over a wide frequency band. The 700924
differential probe lets you make wide-band (100 MHz)
differential input measurements. Just connect the probe
to the input of a single-end input digital oscilloscope.

●

Overrange (outside-range) indicator

This light turns on when the permitted
differential voltage is exceeded. During
DC measurements, it turns on as an
alert at voltages of 350 V and higher
with a 1/100 range setting, and at
voltages of 1400 V and higher with a
1/1000 range setting.

● Power switch

● AC/DC adapter connector

(on side of probe)

This DC adapter powers the probe. The
probe can also be powered by four dry
cells without using an AC/DC adapter.

● 1/100-1/1000 selector switch

This switch is used to select the input
voltage attenuation ratio.
