Accessory for YOKOGAWA DL Series Digital Oscilloscopes
100 MHz band differential probe
NEW
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. 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.
