PicoSource PG900 Pulse Generators Quick Start Guide

1. Introduction

Thank you for purchasing a PicoSource pulse generator.

The fast-transition output from the PicoSource pulse generators can stimulate a

transmission path, device, or network with a broad-spectrum signal in a single

instant. These signals, combined with dierential capability, are invaluable for

making high-speed broadband measurements in many elds such as time domain

reectometry, semiconductor testing, gigabit interconnect and port testing, and radar

systems.

Three dierential output models are available, oering extensive control over pulse

parameters including amplitude, pulse period, pulse width and deskew between

output channels.

• The PicoSource PG911 is a two-channel pulse generator based on Step

Recovery Diode (SRD) technology. It produces two pulses, up to 6 V amplitude

with 60 ps rise time.

• The PicoSource PG912 is a two-channel pulse generator based on Tunnel Diode

(TD) technology. It uses remote tunnel diode pulse heads to produce positive and

negative 200 mV pulses with 40 ps rise time.

• The PicoSource PG914 is a four-channel pulse generator beneting from both

SRD and TD technology.

For further setup information following basic installation, see the User’s Guide by

either clicking the Help menu within the PicoSource PG900 software or opening the

PDF directly from the software disk.

WARNING

To prevent injury or death use the product only as instructed and use only

accessories supplied or recommended. Protection provided by the product

may be impaired if used in a manner not specied by the manufacturer.

2.2 Maximum input and output ranges

Observe all terminal ratings and warnings marked on the product.

The table below indicates the maximum voltage of the outputs and the overvoltage

protection range for the trigger input on each pulse generator. The overvoltage

protection ranges are the maximum voltages that can be applied without damaging

the instrument.

PicoSource PG900 Pulse Generators Quick Start Guide

WARNING

To prevent electric shock or permanent damage to the signal source, do

not connect an input voltage to the integrated pulse outputs or the tunnel

diode pulse heads.

CAUTION

Exceeding the overvoltage protection range on any connector can cause

permanent damage to the instrument and other connected equipment.

2.3 Grounding

WARNING

The instrument’s ground connection through the USB cable is for functional

purposes only. The instrument does not have a protective safety ground.

WARNING

To prevent injury or death, or permanent damage to the instrument, never

connect the ground of an input or output (chassis) to any electrical power

source. To prevent personal injury or death, use a voltmeter to check that

there is no signicant AC or DC voltage between the pulse generator’s

ground and the point to which you intend to connect it.

CAUTION

To prevent signal degradation caused by poor grounding, always use the

high-quality USB cable supplied with the instrument.

2.4 External connections

WARNING

To prevent injury or death, only use the adaptor supplied with the product.

This is approved for the voltage and plug conguration in your country.

To prevent injury or death, do not use the product if it appears to be

damaged in any way, and stop use immediately if you are concerned by

any abnormal behavior.

CAUTION

To prevent damage to the device or connected equipment, do not tamper

with or disassemble the instrument, case parts, connectors, or accessories.

When cleaning the product, use a soft cloth and a solution of mild soap

or detergent in water, and do not allow liquids to enter the instrument’s

casing.

5. Installing the PicoSource pulse generator and software

1. Install the PicoSource PG900 software using the software disk supplied.

Alternatively, you can download the software from picotech.com/downloads.

Follow the on-screen instructions to complete the setup.

Note: Do not connect the pulse generator until the installation is complete.

2. Connect the power cord to the power adaptor, and plug it into a mains (line)

power socket. Then connect the DC power cord to the back of the pulse

generator, and switch on the mains power.

3. Earth (ground) terminal. Some laptop power supplies can produce electrical

noise which may interfere with your measurements. If this occurs, the earth

terminal can be connected to an external ground point (for example, on the

system you are testing) to provide a ground reference for the instrument. This

can help to avoid external noise interfering with your signal. Alternatively, you

can run the laptop using battery power.

4. Connect the pulse generator to the PC using the USB cable supplied. Windows

may automatically display a New Hardware Found notication. Follow any

instructions shown. Note: If Windows asks to connect to Windows Update, select

No.
