1. Introduction
Thank you very much for purchasing the Broadband Direct Current Amplifier T-WBA01Z
made by Turtle Industry Co., Ltd.
This document describes what you will need to know to use the product, including its special
features, how to use it, handling instructions, and other related information.
To ensure correct use of the product you will need to be familiar with electronic circuits
because of its inherent nature. Any wrong usage or mishandling could not only result in
damage to the product but also lead to a serious accident. Please ensure to thoroughly read
and understand this document in thereby enabling correct use of the product.
1.1 Product Outline
The product is a signal amplifier for amplifying broadband signals, including direct current
signals. The product has a 20dB amplification factor at a transmission impedance of 50Ω,
and therefore is suitable as an amplifier in front of an AD convertor. The product runs on a
single power supply of 5 V and thus is easy to handle.
1.2 Product Structure
The product packaging contains:
(1) Main T-WBA01Z body
(2) Dedicated AC/DC adaptor
(3) Four case feet to be attached
* If anything is missing please ensure to contact our Service Support Section. (Refer to
page 9 for contact information.)

3. Description of Each Part
3.1 Input Terminal (INPUT)
The terminal for input of the signals to be amplified.
A BNC connector is used here. An input resistance of between 1M (mega) ohm and 50
ohms can be selected using the input resistance selection switch.
The maximum value for any input voltage is ±5V. Exceeding that voltage could
not only damage the product but also pose the risk of fire or electric shock.
* The DC power supply terminal (DC 5V) and current input terminal (INPUT) are isolated.
(The insulation withstanding voltage is not guaranteed)
* The INPUT shield and OUTPUT shield sides have common potentiality (electrically
connected).
* The INPUT shield and case have common potentiality (electrically connected).
3.2 Output Terminal (OUTPUT)
The terminal will output amplified voltage. Connect it with, for example, an instrument that
measures the voltage input. Both (+) non-inverted and (-) inverted output are supported.
* The OUTPUT shield and INPUT shield have common potentiality (electrically connected).
* The OUTPUT shield and case have common potentiality (electrically connected).
3.3 Zero Adjustment (ZERO)
Used to make any necessary zero adjustments. The adjustable range is ±100mV of the
output (at 50Ω, ±50mV).
(Concerning the driver for use in making adjustments)
W
L
Please use a driver that is (W) 0.3 ~ 0.5 mm thick at the tip which is (L) 1.6 ~ 2.0 mm wide.

3.4 Input Resistance Selection
Used for selecting an input resistance of between 1M (mega) ohm and 50 ohm.
Selecting 50 ohm will result in the head of the switch lighting up green.
* When switching ensure to cut off the power supply first.
3.5 Power Supply Input Terminal (DC 5V)
Connect the accompanying AC/DC adaptor here.
The power supply input terminal is isolated from the ground used for the signal
processing circuit. However, the insulation withstanding voltage is not guaranteed.
