APEX WAVES VB-8054 VirtualBench 4-Channel 500 MHz Bandwidth Oscilloscope User Guide

This document includes compliance precautions and connection information for the VB-8054.

Note The guidelines in this document are specific to the VB-8054.

Safety Guidelines

The following section contains important safety information that you must follow when installing and using the VB-8054.

Do not operate the hardware in a manner not specified in this document and in the user documentation. Misuse of the hardware can result in a hazard. You can compromise the safety protection if the hardware is damaged in any way. If the hardware is damaged, return it to National Instruments for repair.

Hazardous Voltage This icon denotes a warning advising you to take precautions to avoid electrical shock.

Caution Do not operate the VB-8054 in a manner not specified in this document. Product misuse can result in a hazard. You can compromise the safety protection built into the product if the product is damaged in any way. If the product is damaged, return it to National Instruments for repair.

Clean the hardware with a soft, nonmetallic brush. Make sure that the hardware is completely dry and free from contaminants before returning it to service.

Do not substitute parts or modify the hardware except as described in the NI VirtualBench Help. Use the hardware only with the accessories and cables specified in the NI VirtualBench Help or NI VirtualBench VB-8054 Specifications.

Do not operate the hardware in an explosive atmosphere or where there may be flammable gases or fumes.

You must insulate signal connections for the maximum voltage for which the hardware is rated. Do not exceed the maximum ratings for the hardware. Do not install wiring while the hardware is live with electrical signals. Do not remove or add connector blocks when power is connected to the system. Avoid contact between your body and the connector pins when hot-swapping hardware. Remove power from signal lines before connecting them to or disconnecting them from the hardware.

Operate the device only at or below Pollution Degree 2. Pollution is foreign matter in a solid, liquid, or gaseous state that can reduce dielectric strength or surface resistivity. The following is a description of pollution degrees:

Pollution Degree 1 means no pollution or only dry, nonconductive pollution occurs. The pollution has no influence.
Pollution Degree 2 means that only nonconductive pollution occurs in most cases. Occasionally, however, a temporary conductivity caused by condensation must be expected.
Pollution Degree 3 means that conductive pollution occurs, or dry, nonconductive pollution occurs that becomes conductive due to condensation.

Operate the DMM on the device at or below Measurement Category II1 . Operate the mixed signal oscilloscope, function generator (FGEN), external trigger (TRIG), digital I/O, and DC power supply on the device at or below Measurement Category I. Measurement circuits are subjected to working voltages2 and transient stresses (overvoltage) from the circuit to which they are connected during measurement or test. Measurement categories establish standard impulse withstand voltage levels that commonly occur in electrical distribution systems. The following is a description of measurement categories:

Measurement Categories CAT I and CAT O (Other) are equivalent and are for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS3 voltage. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.
Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to locallevel electrical distribution, such as that provided by a standard wall outlet (for example, 115 V for U.S. or 230 V for Europe). Examples of Measurement Category II are measurements performed on household appliances, portable tools, and similar E Series devices.
Measurement Category III is for measurements performed in the building installation at the distribution level. This category refers to measurements on hardwired equipment such as equipment in fixed installations, distribution boards, and circuit breakers. Other examples are wiring, including cables, bus bars, junction boxes, switches, socket-outlets in the fixed installation, and stationary motors with permanent connections to fixed installations.
Measurement Category IV is for measurements performed at the primary electrical supply installation (<1,000 V). Examples include electricity meters and measurements on primary overcurrent protection devices and on ripple control units.

To obtain the safety certification(s) for this product, visit ni.com/certification, search by model number or product line, and click the appropriate link in the Certification column.

Safety Voltages
Connect only voltages that are within these limits.

Measurement Category is defined in electrical safety standard IEC 61010-1. Measurement Category is also referred to as Installation Category.
Working voltage is the highest rms value of an AC or DC voltage that can occur across any particular insulation.
MAINS is defined as a hazardous live electrical supply system that powers equipment. Suitably rated measuring circuits may be connected to the MAINS for measuring purposes.

DMM Isolation Voltages

Hazardous Voltage This icon denotes a warning advising you to take precautions to avoid electrical shock.

Channel-to-earth ground

Continuous: 300 V, Measurement Category II
Withstand: 3,000 V RMS, verified by a 5 s dielectric withstand tes

Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe.

Caution Do not connect the VirtualBench hardware to signals or use for measurements within Measurement Categories III or IV.

DC Power Supply Isolation Voltages

+25 V and -25 V-to-earth ground, continuous: 60 V DC, Measurement Category I

Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.

Power Requirements

Caution The protection provided by the VirtualBench hardware can be impaired if it is used in a manner not described in the NI VirtualBench VB-8054 Safety, Environmental, and Regulatory Information.

Voltage input range: 100 V AC to 240 V AC, 50/60 Hz
Power consumption: 150 W maximum
Power input connector: IEC C13 power connector
Power disconnect: The AC power cable provides main power disconnect. Do not position the equipment so that it is difficult to disconnect the power cable. Depressing the front panel power button does not inhibit the internal power supply

Preparing the Environment

Ensure that the environment you are using the VB-8054 in meets the following specifications.

Operating temperature 0 °C to 40 °C
Cooling Forced air circulation (negative pressurization) through a fan. Fan speed automatically adjusts according to operating conditions. Intake locations are on the sides of device. Exhaust location is on the rear of device. Ensure that the intake and exhaust locations are not obstructed.
Pollution Degree 2
Maximum altitude 2,000 m

Indoor use only.

Note Refer to the NI VirtualBench VB-8054 Specifications for complete specifications.
