General Information

Operating and Safety Precautions

Operating

You need observe only normal precautions when handling and operating the

16065C. Do not exceed the operating input power, voltage, and current level

and signal type appropriate for the measurement instrument being used, refer

to your instrument's operation manual.

Service

The voltage levels in this adapter do not warrant more than normal caution for

operator safety. Nevertheless, service should be performed only by qualified

personnel.

Electrostatic discharge (esd) can damage the highly sensitive microcircuits

in your instrument. ESD damage is most likely to occur as the 16065C is

being connected or disconnected. Protect the 16065C from ESD damage

by wearing a grounding strap that provides a high resistance path to

ground. Alternatively, ground yourself to discharge any static charge

build-up by touching the outer shell of any grounded instrument chassis

before touching the test port connectors.

Never touch a test port connector's center contacts.

Use a work station equipped with an anti-static work surface.

2 Operating and Safety Precautions

Introduction

This chapter explains how to install the 16065C External Bias Adapter. The

topics covered include initial inspection, ambient environmental

considerations, connecting the adapter for use, and repackaging the adapter.

Initial Inspection

The adapter has been carefully inspected electrically and mechanically before

being shipped from the factory. It should be in perfect physical condition, no

scratches, dents or the like, and it should be in perfect electrical condition.

Verify this by carefully performing an incoming inspection to check the adapter

for signs of physical damage and missing contents. If any discrepancy is found,

notify the carrier and Keysight Technologies. Your Keysight Technologies sales

office will arrange for repair and replacement without waiting for the claim to

be settled.

Step 1. Inspect the shipping container for damage, and keep the shipping materials

until the inspection is completed.

Step 2. Verify that the shipping container contains everything shown in Figure 2-1

and listed in Table 2-1.

Step 3. Inspect the exterior of the 16065C for any signs of damage.

Repackaging the Adapter

If shipping to a Keysight Technologies service center is required, each adapter

should be repackaged using the original factory packaging materials.

Alteratively, comparable packaging materials may be used. Wrap the adapter

in heavy paper and pack in anti-static plastic packing material. Use sucient

shock absorbing material on all sides of the 16065C to provide a thick, firm

cushion and to prevent movement. Seal the shipping container securely and

mark it FRAGILE.

Make sure that the voltage source is turned off before you start making

connections.

Introduction

This chapter describes the features of the 16065C (Figure 3-1), the connection

to an external voltage source and test fixture, and compensation techniques.

Figure 3-1 Adapter Features

1. Four-terminal-pair test leads. These are connected to the UNKNOWN

terminals of an LCR meter or impedance analyzer.

2. Four-terminal-pair BNC terminals. These terminals are connected to a

four-terminal-pair type fixture.

3. DC Bias Input BNC. This terminal is connected to an external voltage

source in order to apply dc bias voltage to the DUT.

14 Keysight 16065C External Bias Adapter

Operation

OPEN/SHORT Correction

The 16065C has inherent stray capacitance, residual inductance, and residual

resistance which, if not properly compensated for before a measurement is

made, will degrade measurement accuracy. To cancel these residuals and thus

minimize measurement error, the measuring instrument's OPEN/SORT

correction capability must be used. The procedure is described in the

instrument's operation manual.

Operation

The step-by-step instructions on how to make a measurement with the

16065C are:

Step 1. Connect the test leads of 16065C to the measuring Instrument's UNKNOWN

terminals.

Step 2. Connect the test fixture directly to the 16065C.

Step 3. Connect the dc voltage source to the 16065C's DC BIAS INPUT BNC.

Step 4. Perform OPEN and SHORT correction as described in the measuring

instrument manual.

Step 5. Insert the component to be tested into the test fixture.

Do NOT turn on the voltage source while correction is in progress.

Do NOT short the high and low terminals when the voltage source is turn

on.

When a positive bias vol tage is used, the positive terminal of an electrolytic

capacitor must be connected to the instruments high terminal. When using

a negative bias voltage, connect an electrolytic capacitor's negative

terminal to the instrument's high terminal.

When measuring high value capacitors, allow suffcient time for the

capacitor to charge to the applied voltage.

Keysight 16065C External Bias Adapter 15

Operation

DC Bias

You Can NOT Use the Internal DC BIAS Source of Your Instrument

The 16065C contains a 100 µF capacitor, series connected between the H

cur

terminal and the component under test. Its function is to block the applied dc

voltage from flowing back into the measuring instrument. Also, because of its

location, this capacitor makes it impossible to bias samples from the

measuring instrument's internal bias source. Thus, the 16065C can not be used

for applications in which the instrument's internal bias source is used.

Requirement for External Voltage Source

The external dc voltage source used for biasing samples connected to the

16065C must be

capable of delivering 20 mA at 40 V.

Current Limiting

The 16065C's DC Bias Input has a 2 kΩ current limiting resistor in series with

the component under test.

Capacitive Component Requires Time to Charge

The 16065C DC BIAS INPUT has a 2 kΩ current limiting resistor in series with

the component under test. The time required for a capacitive component to

charge through this resistance is calculated as:

T(s) = 1.6 + (0.01 × C) [sec]

Where C is the capacitance of the sample, in µF.

16 Keysight 16065C External Bias Adapter

Operation

DC Bias

Additional Error for D Measurement

Because of the series-connected capacitor between the H

pot

terminal and the

component under test, there is a test frequency dependent phase shift

between the H

pot

terminal and the L

cur

terminal. The input impedance of the

instrument causes additional error in some measurement modes. The

additional error for phase measurements (Ep) is derived by the following

equation:

_ 70 / f (%)

(Typical)

where f is measurement frequency and unit is Hz.

The additional error for D measurements (E

) is derived by the following

equation:

_ 0.7 / f

(Typical)

The compensation function of the E4981A and E4980AL can correct the

additional error caused by the 16065C. For more information on

compensation and correction, refer your instrument's manual.
