WBK61 and WBK62

Description

The WBK61 and WBK62 are single-channel high-voltage adapters that can be used with WaveBooks, or
with WBK10A expansion modules. In addition, WBK61 and WBK62 can be used with WBK11A,
WBK12A and WBK13A signal conditioning cards.

Voltage Divider 200:1

Maximum Voltage 1000 Vpeak

The channel output connection [for both the WBK61 and WBK62 voltage adapters] is made through a
BNC-to-BNC coupler. Each model has two signal input-connections, one for low-signal input, and the other
for high-signal input. The input channels are resistively isolated from ground, providing for safe connection
of the test device. Series resistors, for both high and low channels, serve as attenuators and provide a
maximum current limit of 100 µA.

WBK61 and WBK62 Schematics

Note 1

: Channel input connections are made from the WBK61/62 BNC to a Channel BNC on the WaveBook data

acquisition system or to the WBK10A analog expansion module. A CN-110 BNC-to-BNC Coupler is used to
make the connection. Refer to the Hardware Setup section of this document module for information regarding
channel and ground connections.

Note 2

: The variable resistors are factory set at 50 KΩ and are not user-adjustable.

Hardware Setup

Refer to the following steps and figures to connect the high voltage adapter. Note that we will use the term
“WBK61/62” to refer to both WBK61 and WBK62 since the installation of these models is identical.

1. Connect WBK61/62 to any input channel(s) of the WaveBook or WBK10A module using the supplied
BNC-to-BNC coupler (CN-110). Refer to the following figures.

2. If connecting only one WBK61/62, connect the green stacking banana plug to analog common (J12)
on the WaveBook or WBK10A module.

WARNING

WARNING

WARNINGWARNING

High voltages can cause death or severe injury. Do not connect or disconnect the
probes from WBK61 or WBK62 when the leads are connected to a voltage source.

WARNING

WARNING

WARNINGWARNING

Failure to properly connect a WBK61 or WBK62 to the acquisition device
(WaveBook or WBK10A) and to ground will result in unsafe operation.

If connecting two or more WBK61/62s, connect the green stacking banana plug of the first WBK61/62 to
analog common (J12) on the WaveBook or WBK10A module. Connect the other WBK61/62 stacking
banana plugs to the adjacent WBK61/62 earth ground connections (see following figure).
