Section 1 Introduction

1.1

Product Overview

This system is a network analyzer used to measure transmission and reflection (external reflection bridges are also used)
characteristics of electronic parts and circuits over a wide frequency range of 10 Hz to 300 MHz.
This system has a 6.5-inch flat display (640 × 480 dots). This display is a color LCD based on an active matrix drive
system.
The display shows a soft key menu, various measurement graphs, and measurement parameters to allow you to specify
parameters, make measurements, and output measurement results to the printer and plotter.
This system incorporates measurement ports R, TA, and TB (option), allowing you to measure port-to-port ratios and
absolute levels.
This system has a GPIB interface as standard, so you can configure an automatic measurement system easily by connecting a personal computer and other measuring devices. This system also has a PTA (Personal Test Automation) function
as standard, so you can use this system as a controller to construct an automatic measurement system without using an
external personal computer.
■ Applications
This system can be widely used when developing, adjusting, and inspecting electronic parts and devices in the communications market (for mobile and optical communications, etc.) and the AV market (for high-quality TVs and satellite
broadcasting). Especially, the macro analysis function for filters and piezoelectric resonators facilitates and accelerates
measurements.

Section 2 Preparations before Use

2.4.1

Connecting the Power Cord

Check that the POWER switch on the front panel is turned off (switched to the (O) side).
Insert the power plug into an outlet, and connect the other end to the power inlet on the rear panel. To ensure that the
instrument is grounded, always use the supplied 3-pin power cord, and insert the plug into an outlet with a ground
terminal. (2) Grounding using a conversion adapter

WARNING
If the power cord is connected without the instrument grounded, there is a risk
of receiving a fatal electric shock. In addition, the peripheral devices connected to the instrument may be damaged.
When connecting to the power supply, DO NOT connect to an outlet without a
ground terminal. Also, avoid using electrical equipment such as an extension
cord or a transformer.

CAUTION
If an emergency arises causing the instrument to fail or malfunction, disconnect the instrument from the power supply by either turning off the POWER
switch on the front panel (switch to the (O) side), or by pulling out the power
cord or the power inlet.

Notes on Handling Storage Medium
CAUTION
Do not remove a storage medium, such as a plug-in memory card or floppy
disk, while it is being accessed. While a storage medium is being accessed,
the BUSY lamp is lit. If a storage medium is removed while it is being accessed, the data recorded on it could be destroyed.

This system uses a floppy disk (or an optional plug-in memory card) to store setting data and programs.
Abusing a storage medium could erase the data on it. It is recommended that backup copies of important data be created.
We assume no responsibility for loss of the data stored on storage media.
Notes on handling floppy disks and the plug-in memory card are provided in the following section.

Turning ON the Power

Before turning ON the system, establish a protective ground according to Section 2.2 and then plug the enclosed power
cord into the wall outlet.

WARNING
Turning ON the power without establishing a protective ground could cause
electric shock which might result in severe injury or loss of life. If you do not
have a 3-pole (ground-type, 2-pole) wall outlet, be sure to connect the FG terminal on the rear panel or the ground terminal of the enclosed power cord to
the ground level before turning ON the system.

The Basics of Key Operations

Three types of keys are used to operate the MS4630B Network Analyzer.

3.7.1

Hard keys (master keys)

Pressing hard keys (master keys) on the front panel performs the associated functions and displays a soft key menu.
Pressing marker keys and hard keys in the Measurement section allows you to enter numeric values such as measurement
conditions.

NOTE:
Usually, use numeric keys or the rotary knob to enter numeric values.

3.7.2

Soft keys

A soft key menu appears at the right of the LCD.
Pressing the soft key (F1 to F6) corresponding to a desired menu option performs the associated function.

NOTE:
When there are two or more menu pages, the top label of each menu page indicates a menu page number (e.g., 1/2).
Since the system has a menu learning function, pressing a hard key allows you to access the menu page that you
accessed most recently.

3.7.3

Operation windows

Keys for displaying windows.
Selecting a menu label containing “←” displays an operation window (hereafter simply called a window).
Setting items that are rarely changed and items that require you to select many parameters are displayed in these windows.

under the soft key.

Channels and Traces

This system has two measurement channels: channel 1 (CH1) and channel 2 (CH2).
“Channel” refers to a set of internal hardware resources necessary for performing measurements. For example, settings of
a measurement frequency and an analysis port are included in the settings of a channel. Since there are two channels, two
measurements can be performed using one measuring device. *1
One channel has two traces: trace A (TR_A) and trace B (TR_B).
“Trace” refers to the displayed result of measurement performed in a channel. Two traces appear only when a measurement result is displayed with respect to two parameters such as “magnitude” and “phase,” allowing you to make various
settings for each trace.
For example, a marker setting is included in a trace setting.
As stated above, this system allows you to obtain a maximum of four traces for two channels. *2

NOTE:
*1

3-16 .

When a channel contains only one hardware resource, two measurements cannot be performed at the same
time. They must be performed one at a time (e.g., frequency, then output level).
However, the limit test function may come under certain restrictions (See 6.3.1).

Section 4
Selecting Measurement Items (Channels Group)

List sweep

What is list sweep?
The device stores in itself the measurement conditions corresponding to the measurement points on the frequency axis
(horizontal axis) in the measurement screen, as data tables. In the actual sweep measurement, the device refers to the data
in these tables to set the conditions.
There are the following four types of data tables that store such measurement conditions:
•
•
•
•

Frequency data table
Level data table (used at the time of power sweep)
RBW data table
User wait data table

NOTE:
These data tables exist independently for each measurement channel.
If both measurement channels are to be used in the same measurement conditions, i.e., if the coupled channel
function is turned ON, only the data tables for the active channel are used for the measurement.
If a measurement parameter is changed, a value calculated inside the device according to the value of the said measurement parameter is reflected in these data tables.
If, for example, a frequency parameter such as the center frequency or the frequency span is set, a calculation is carried
out based on these frequency parameters to equalize the frequency intervals between the measurement points in the case
of linear sweep, the result of which is reflected at each point in the frequency data table.
Thus, changing the measurement parameters normally creates these data tables. However, regardless of the values of
these measurement parameters, you can change the measurement condition at any given point in a data table to carry out
the measurement.
List sweep refers to sweeping according to a condition that a user has arbitrarily set for each measurement point by
changing the said condition data in a data table.
The user does not need to set whether list sweep is done or not.
Modifying, changing, and registering data in the data table edit screen (LIST SWEEP EDIT menu) will cause the sweep
to be performed using the new measurement conditions in the next measurement.
These data tables can be saved to or recalled as files from auxiliary storage media such as floppy disks, internal memory,
and memory cards.

5-13

Section 5 Selecting Measurement Parameters (Measurement Group)
The following explains the details of measurement condition data tables.
(1)

Frequency data table
A frequency data table stores the data of measurement frequencies corresponding to each measurement point (Xaxis).
Normally, when a measurement parameter related to frequencies such as the center frequency or the frequency
span is set, the data for all the measurement points at that time is automatically created inside the device.

(2)

Level data table
A level data table stores the data of output power corresponding to each measurement point (Y-axis).
The data in this table is used to carry out power sweep.
Normally, when a measurement parameter related to the power sweep function is set, the data for all the measurement points at that time is automatically created inside the device.

(3)

RBW data table
A RBW data table stores the RBW values corresponding to each measurement point.
Normally, when a measurement parameter such as RBW and the sweep time is set, the data for all the measurement points at that time is automatically created based on the same RBW value.

(4)

User wait table
A user wait table stores the user wait time corresponding to each measurement point.
Normally, when a measurement parameter such as the sweep time and RBW is set, the wait time elapsing between
switching the measurement frequency at each measurement point and starting the measurement is set as the same
value for between all the measurement points.
The user wait function allows you to set any additional wait time for any given point in addition to the preset wait
time.
All the initial values of the user wait time are set to 0 seconds.

NOTE:
Changing a measurement parameter automatically updates the contents of these data tables that generally store the
measurement conditions. Therefore, changing a data table for the purpose of list sweep and then setting a related
measurement parameter again will update the data tables.
To prevent these tables from being updated when a measurement parameter is set, use the F3: LIST SWEEP
GUARD function in the SWEEP (2/2) menu.

Section 5 Selecting Measurement Parameters (Measurement Group)
Power:
Indicates the output power corresponding to each measurement point.
This item is used if the power sweep function is turned ON. Otherwise, this item indicates ******** and cannot be
changed.
Description of operation
The list screen, when brought up, shows the data entry area, “LIST CURRENT POINT:” (in which a numeric value can
be entered) at the bottom.
This data entry area shows the current point (the measurement point number at which the measurement conditions can be
changed).
The current point also matches the measurement point number enclosed inside a square
in the list screen.
Use the data knob, Up/Down keys, and ten-key pad to change the current point. Then, the indication in the list screen
changes according to this change.
The current point may be set in the range from 0 through 1000.

Section 8 Calibration (Calibration Group)

8.1

Explanation

This system supports the following two methods of correcting errors in the values measured by the measuring system:
Normalization
Vector error calibration
These methods have both advantages and disadvantages, so you must select either method according to your purpose.
Let’s take a look at the differences between these two methods.
Features of normalization
The normalize calibration method finds the difference between the waveform data displayed on the screen and the reference data obtained in advance. This operation is performed on the waveform displayed on the screen after it is processed
to the analysis format (e.g., amplitude and phase), and not on the measured signals (vector with magnitude and phase
angle).
Features of vector error calibration method
A device with known characteristics is measured by a measuring system, the measured value is compared with the logical
value to obtain the error in the value measured by the measuring system, then this error is corrected. This calculation is
performed for the measured signal (vector quantity) which has not been converted to a waveform. This method is further
classified into some methods depending on the type of the error to be corrected.
The greatest difference is that the calculation is performed before or after conversion of measurement data to a display
waveform. The vector error calibration method does not require recalibration if the waveform display mode is changed
(e.g., from MAG to MAG/PHASE). On the other hand, the normalization method requires recalibration. Generally, the
vector error calibration is more complicated and requires more time and effort than the normalization method.

Normalization (X-S)

8.2.1

Fetching reference data

X→S

Normalization (X-S)

Fetch the reference data for normalization.

•

The normalization method displays the difference between the reference data stored in the system and the data obtained by actually carrying out a sweep measurement.

•

The difference is obtained for the scalar data obtained after processing data into the selected analysis format (MAG,
PHASE, DELAY, etc.). The reference data is also stored as scalar data.

NOTE:
•
•
•

8.2.2
X–S

When PHASE is selected as an analysis format (PHASE, θ), the result value is converted to a value which is
between –180˚ and +180˚.
This function can be used for simple calibration of frequency responses.
Pressing this key starts the uptake sweep of reference data and, after the sweep is completed, turns the normalize calibration ON. In the following sweep and thereafter, the calibrated measurement waveform is displayed.

Turning the normalization function ON/OFF
Turn ON/OFF the normalization function.

NOTE:
Turning the normalization function ON, “S” is displayed on the left side of the display as showing this condition.
Turning the normalize function OFF does not delete the reference data taken into the device. Changing the measurement conditions or recalling a file from a floppy disk, internal memory, or PMC turns the normalize function
OFF. The normalize function is performed independently for each measurement channel. Therefore, to use the
normalize function for both of the measurement channels, the reference data must be read for each of the channels.

Interpolating Calibration Data

If the measurement frequency range and measurement point are changed after completion of vector error calibration, it is
common practice to create new calibration data to obtain a correct calibration result. With this system, however, press
from the soft key menu after setting a new frequency and point compares the old one with the new one
CAL ON
to create calibration data for the new frequency and point, allowing you to obtain a calibration result which is close to the
calibration result obtained using new calibration data.

NOTE:
If a new frequency is not included in the old frequency range, the result of calibration for the new frequency may
become incorrect.
Or, “ I ” is indicated on the left side of the display, because the data is not interpolated by the latest calibration.

12.1

Analyzing a Network

The network analyzer analyzes a network by measuring its transfer and reflection characteristics using a sine wave.
Transfer characteristics are represented by Etr/Ein (Etr means a transmission voltage and Ein means an input voltage) and
reflection characteristics are represented by Ere/Ein (Ere means a reflection voltage and Ein mean an input voltage). The
transfer and reflection characteristics of the network can be obtained by measuring the ratio between Etr and Ein magnitudes, ratio between Ere and Ein magnitudes, the difference in phase between Etr and Ein, and the difference in phase
between Ere and Ein.
In addition to the basic items, such as an magnitude and phase, that represent transfer and reflection characteristics of a
network, the items listed below which are obtained from the basic items are used. When combined with a reflection
bridge, this system can measure transfer and reflection characteristic. When not combined with a reflection bridge, this
system can measure only transfer characteristics.

Section 12 Measurements

12.2

Basics of Measurement

This section explains important basic items that must be set in addition to measurement items.
(1)

Dynamic range
(a) Dynamic range
A dynamic range is defined from the maximum input level to the average noise level. “Maximum input level”
does not mean the absolute maximum rating specified for protecting the system but it means the maximum
input level specified for maintaining the linearity of the receiver circuit (i.e., input range of each reception
port). To make measurements accurately, a sufficient dynamic range must be allocated for the DUT and the
highest possible part of the dynamic range must be used.
(b) Output power and input attenuator
To use the highest possible part of the dynamic range, adjust the output power to the input range when measuring an ordinary passive circuit. When measuring a passive circuit which requires a large insertion loss and
wide dynamic range, increase the output power to the maximum so that overload does not occur. However,
the output level must be lowered to the input range when calibrating the measuring system.
For a DUT which has a gain (e.g., amplifier), the output power must be lowered below the input attenuator
level by the gain. If the input range of the receiver circuit is exceeded, the OVER message lamp lights.
Reduce the test port power or increase the input range.
(c) Resolution bandwidth (RBW)
The average noise level of the receiver circuit is determined by the resolution bandwidth (RBW). The resolution bandwidth must be selected according to the dynamic range.

(2)

Sweep time and number of measurement points
(a) Sweep time
The narrower the resolution bandwidth, the longer the sweep time. Normally, an optimum sweep time is
automatically set according to the resolution bandwidth.
(b) Number of measurement points
Short sweep times are required, for example, when adjusting a DUT. You can select the number of measurement points out of 11, 21, 51, 101, 251, 501, and 1001. To reduce the sweep time, decrease the number of
measurement points.

Measuring Transfer Characteristics

Transfer characteristics are the most basic measurement items used for network analysis. Using a band pass filter with a
center frequency of 90 MHz, carry out the following measurements:
•
•
•

Measurement of logarithmic magnitude: Single trace
Simultaneous measurement of magnitude and phase: Dual trace
Measurement of impedance by transfer method

Measuring Transfer Characteristics

Measuring impedance using a transfer method

This system can measure impedance using two methods: a method by which a reflection characteristic is measured using
a reflection bridge and a method by which a transfer characteristic is measured. This section explains the procedure for
measuring impedance using the latter method (transfer method).
When the transfer method is used, a pi network jig is used normally. Let’s measure the impedance of the 1 µH inductance
using a pi network jig whose measurement terminal impedance is 12.5 Ω and obtain the R-L (or C) series equivalent
constant.

12.4

Measuring Reflection Characteristics

If the input impedance of a test device is different from the impedance of the measuring system when incident energy is
applied to the input terminal on the test device, part of the energy is reflected. The ratio of the reflected energy to the
incident energy is called a reflection coefficient, providing the standard for reflection measurement. For example, calculating the logarithm of the absolute value of the reflection coefficient gives a return loss. If a reflection coefficient is
known, a VSWR can be calculated from (1 + Absolute value of reflection coefficient)/(1 - Absolute value of reflection
coefficient). To calibrate the reflection measurement result, 1PORT OSL calibration can be used in addition to RESPONSE calibration. Let’s carry out the following measurements using a band pass filter with a center frequency of 90
MHz:
•

Measurement of return loss

•

Measurement of reflection coefficient

•

Measurement of impedance

•

Measurement of VSWR

12.4.1

Measurement of return loss

Select a LOGMAG as an analysis format. When this format is selected, the ratio of reflected energy to incident energy is
measured in dB, allowing you to read the return loss directly.
In the measurement procedure described below, RESPONSE calibration is used.

Measuring a reflection coefficient

When measuring a reflection coefficient, select a LIN MAG format and polar coordinate graph. In the LIN MAG mode,
the ratio of reflected energy to incident energy is measured linearly, allowing you to read the absolute value of the
reflection coefficient directly. The polar coordinate graph allows the complex reflection coefficient Γ=ρ∠θ (ρ = absolute
value of reflection coefficient, θ = phase angle) to be measured at the same time. Since the polar coordinate system does
not have a frequency axis, use the marker to read frequencies. In the measurement procedure described below, 1PORT
OSL calibration is used.
