Caution

Do not exceed the operating input power, voltage, and current

level and signal type appropriate for the instrument being used, refer to your instrument's Function Reference.

Electrostatic discharge(ESD) can damage the highly sensitive

microcircuits in your instrument. ESD damage is most likely to occur as the test fixtures are being connected or disconnected. Protect them from ESD damage by wearing a grounding strap that provides a high resistance path to ground. Alternatively, ground yourself to discharge any static charge built-up by touching the outer shell of any grounded instrument chassis before touching the test port connectors.

Checking the Shipment

After you receive the E4980A, carry out checks during unpacking according to the following procedure.

WARNING If the external face of the LCR meter (such as the cover, front/rear panel, LCD screen,

power switch, and port connectors) appears to have been damaged during transport, do not turn on the power switch. Otherwise, you may get an electrical shock.

Step 1. Check that the packing box or shock-absorbing material used to package the LCR meter

has not been damaged.

NOTE If the packing box or shock-absorbing material has been damaged, leave the packing box

and shock-absorbing material as is until other inspection items are checked as follows:

Step 2. Check the packaged items supplied with the LCR meter for any damage or defects.

1.Unpacking and Preparation

Step 3. Referring to Table 1-1 and Figure 1-1, check that all packaged items supplied with the LCR

meter have been provided as per the specified options.

Step 4. After checking, if one of the following applies, contact your nearest Agilent Technologies

sales and service office.

1. The packing box or shock-absorbing material used to package the LCR meter has been damaged or the shock-absorbing material displays traces of where extreme pressure has been applied.

2. A packaged item supplied with the LCR meter has mechanical damage or defects.

3. A packaged item supplied with the LCR meter is missing.

4. A fault has been detected in the subsequent operation check of the LCR meter.

If an abnormality is detected in Step 1, contact the company that transported the LCR meter as well as your nearest Agilent Technologies sales and service office. For inspection by the transport company, save the packing box, shock-absorbing material, and packaged items as you received them.

This chapter provides the basic procedures for operating the E4980A and describes names and functions of the front panel, rear panel, and screen display.

Overview

Product Introduction

The Agilent E4980A is a general-purpose LCR meter for incoming inspection of components, quality control, and laboratory use. The E4980A is used for evaluating LCR components, materials, and semiconductor devices over a wide range of frequencies (20 Hz to 20 MHz) and test signal levels (0.1 mVrms to 2 Vrms, 50 μA to 20 mArms). With Option 001, the E4980A’s test signal level range spans 0.1 mV to 20 Vrms, and 50 μA to 200 mArms. Also, the E4980A with Option 001 enables up to ±40-Vrms DC bias measurements (without Option 001, up to ± 2 Vrms), DCR measurements, and DC source measurements using the internal voltage source.

The E4980A offers C-D measurement with a basic accuracy of ±0.05% (C), ±0.0005 (D) at all frequencies with seven-digit resolution (the dissipation factor resolution is 1 ppm) in every range.

With its built-in comparator, the E4980A can output comparison/decision results for sorting components into a maximum of ten bins. Furthermore, by using the handler interface and scanner interface options, the E4980A can be easily combined with a component handler, a scanner, and a system controller to fully automate component testing, sorting, and quality-control data processing.

The E4980A’s list sweep function permits entry of up to 201 frequencies, test signal levels, or bias level points to be automatically measured.

The GP-IB/LAN/USB interfaces are standard interfaces on the E4980A and enable automatic testing.

Measurement Function

The E4980A simultaneously measures two components of the complex impedance (parameters) in a measurement cycle.

Regardless of the types of measurement parameters, the test signal voltage (VAC) and the test signal current (IAC) are measured at the same time. When the E4980A is equipped with option 001, the DC bias voltage level (VDC) and the DC bias current level (IDC) are measured simultaneously.

NOTE Regardless of the types of measurement parameters, the measurement result for the R-X

parameter can be obtained using the SCPI command.

When the E4980A is equipped with option 001, DC resistance (Rdc), DC voltage (Vdc), and DC current (Idc) can be measured instead of impedance.

Types of measurement parameters

Types of measurement parameters are shown below.

You do not need to select the impedance range.

No ranging time is required.

The measurement time is longer due to the ranging time.

You need to select a proper range depending on the value of the DUT.

Effective meausrement range for each impedance range for impedance measurement

Figure 3-3 shows the range that can be displayed and the effective measuring range for each impedance range while in the impedance mode (| Z |, R, X). For example, 50-kΩ DUT impedance can be measured using the ranges of 100 kΩ to 30 kΩ, but the E4980A’s accuracy specification is only met when using the 30-kΩ range. If this DUT is measured with the 100-kΩ range, “OVERLOAD” will be displayed.

Effective measurement range for each impedance range

The following shows the effective measurement range of each impedance range, in which the E4980A’s measurement accuracy meets its specifications.

When the impedance range is set manually, the optimum impedance range should be selected by matching the impedance of the DUT to the effective measurement range shown in

Figure 3-4, Figure 3-5, and Figure 3-6. When the impedance range is set to AUTO, the optimum impedance range is automatically selected according to the impedance of each DUT.

NOTE The impedance range is limited by the test frequency setting when the test signal level is

less than or equal to 2 V. When the impedance range and test frequency are set under the above conditions, the test frequency must be set first, followed by the impedance range. If you set the impedance range first and then frequency, the resulting impedance range may not be the one you wanted to set.

Test Signal Level

The E4980A’s test signal level can be set as the effective value (RMS value) of a sine wave of the test frequency from the unit’s internal oscillator. You can set either the oscillator

voltage level or the oscillator current level. The output impedance is 100 Ω.

NOTE The set value of the oscillator current level is the value set when the measurement contacts

(UNKNOWN terminals) are shorted together.

The set value of the oscillator voltage level is the value set when the measurement contacts (UNKNOWN terminals) are opened.

The E4980A can measure a device using a constant voltage or current level by using the automatic level control function. (The automatic level control function (ALC field) can be set to ON from the MEAS SETUP page.) When a constant voltage or current level measurement is performed, an asterisk mark (*) appears at the end of the LEVEL display. For more information about the automatic level control function, refer to control” on page 96.

DC Bias

The E4980A has an internal DC bias. A DC bias is output when the DC Bias key on the front panel is set to ON.

The DC Bias key is a toggle-type switch used to enable DC bias output. When you press the DC Bias key, bias is ON (orange). When you press the DC Bias key again, status display area and the LED indicator is OFF. If the DC Bias key is set to OFF, the setting value for the DC bias is not output even though the DC bias is set to ON in the BIAS field.

The setting value of the DC bias signal voltage is the value set when the measurement contacts (UNKNOWN terminals) are opened.

The setting value of the DC bias signal current is the value set when the measurement contacts (UNKNOWN terminals) are shorted.

Comparator Function ON/OFF

The E4980A’s built-in comparator can sort devices into a maximum of ten bins (BIN 1 to BIN 9 and the OUT OF BIN) using a maximum of nine pairs of primary parameter limits and one pair of secondary parameter limits. Also, a device whose primary parameter is within limits, but whose secondary parameter measurement result is not, can be sorted into an auxiliary BIN (AUX BIN). To control a component handler using the comparator function, it is necessary to install option 201.

These limits settings for bin sorting are set on the LIMIT TABLE page from the [MEAS SETUP] key (refer to Chapter 4). Therefore, this COMP field allows you to only set the comparator function to ON or OFF.

Procedure for setting the comparator function

Step 1. Press the [Display Format] key.

Step 2. Press the BIN No. softkey.

Trigger mode

Functional Description

The E4980A supports four trigger modes: INT (internal), EXT (external), MAN (manual), and BUS (GPIB bus).

For more on the E4980A’s trigger system, see “Trigger System” on page 247 in Chapter 8, Overview of Remote Control

Trigger mode Description

INT After you bring up the display page using the [Display Format]

key, the instrument continuously repeats the measurement cycle.

MAN After you bring up the display page using the [Display Format]

key, the instrument performs one cycle of measurement each time you press the [Trigger] key.

EXT After you bring up the display page using the [Display Format]

key, the instrument performs one cycle of measurement each time a rising TTL pulse is input to the external trigger input terminal on the rear panel. In the EXT (external trigger) mode, you can also trigger the instrument by short-circuiting the core wire of the external trigger input terminal and the instrument’s ground line (the core wire is connected to a circuit that contains a pull-up resistor).

Figure 4-2 shows the TTL pulse specifications.

Also, you can trigger the instrument from the handler interface or scanner interface.

BUS The E4980A performs one cycle of measurement each time it

receives a trigger command sent via GPIB/USB/LAN.

NOTE E4980A ignores any trigger that is input during a measurement cycle. Be sure to trigger the

instrument when it is not in a measurement cycle.
