This product is a Class A (for industrial environment) product. Operation of this product in a
residential area may cause radio interference in which case the user will be required to correct the
interference.
Cable conditions
Probe power cable
Attach a ferrite-core (TDK: ZCAT2035-0930A, YOKOGAWA: A1190MN) to the instrument end
of the cable by passing the cable twice through the core (see the figure below).
Trigger output cable
Attach a ferrite core (TDK: ZCAT2035-0930A, YOKOGAWA: A1190MN) to the instrument end
of a BNC cable. Use cables that are 3 m or less in length.
Video signal output cable
Attach a ferrite core (TDK: ZCAT2035-0930A, YOKOGAWA: A1190MN) to each end of a
D-Sub 15-Pin VGA shielded cable. Use cables that are 3 m or less in length.
GP-IB cable
Use a shielded cable that is 3 m in length or less.
Ethernet cable
Use Ethernet cables that are 30 m or less in length.
USB cable for peripherals
Attach a ferrite-core (TDK: ZCAT2035-0930A, YOKOGAWA: A1190MN) to the instrument end
of a USB cable by passing the cable twice through the core (see the figure below). Use cables
that are 3 m or less in length.
USB cable for PCs
Attach a ferrite-core (TDK: ZCAT2035-0930A, YOKOGAWA: A1190MN) to the instrument end
of a USB cable by passing the cable twice through the core (see the figure below). Use cables
that are 3 m or less in length.
GO/NO-GO output cable
Use the dedicated GO/NO-GO cable (YOKOGAWA: 366973), which is sold separately. Attach
a ferrite-core (TDK: ZCAT2035-0930A, YOKOGAWA: A1190MN) to the instrument end of the
cable by passing the cable twice through the core (see the figure below).
Example of passing the cable through twice
*1 The overvoltage category (installation category) is a value used to define the transient overvoltage condition and includes
the rated impulse withstand voltage. II applies to electrical equipment that is powered through a fixed installation, such as a
switchboard.
2 Pollution Degree applies to the degree of adhesion of a solid, liquid, or gas that deteriorates withstand voltage or surface
resistivity. Pollution degree 2 applies to normal indoor atmospheres (with only non-conductive pollution).
3 The measurement category of this instrument’s signal input terminals is Other (O). Do not use it to measure the main power
supply or for Measurement Categories II, III, and IV.
Measurement category O applies to measurement of circuits that are not directly connected to a main power source. This
category applies to measurement of secondary electric circuits in equipment across a transformer. The estimated transient
overvoltage that may appear at the instrument’s signal input terminals is 1600 V.
Measurement category II applies to measurement of circuits, such as household electric appliances and portable electric tools,
that are connected to low-voltage installations.
Measurement category III applies to measurement of facility circuits, such as distribution boards and circuit breakers.
Measurement category IV applies to measurement of power source circuits, such as entrance cables to buildings and cable
systems, for low-voltage installations.
