Introduction to the Multiport Test Set
Introduction to the Multiport Test Set
•
The 87075C is a 75-ohm multiport test set that is available with 6 or 12 test
ports.
A Complete Multiport Test System
87075C multiport test sets are designed to work with E5061A (1.5 GHz) and
E5062A (3 GHz) RF network analyzers to provide complete measurement systems
for 75 ohm multiport devices. These test systems offer fast measurement speed, high
accuracy, and productivity features that will maximize your production throughput.
They feature:
•
specified performance to 1.3 GHz (87075C)
•
solid-state switches for fast, repeatable, and reliable switching between
measurement paths
Fully Characterize Your Devices with a Single
Connection
A single connection between the multiport test set and each port of the DUT allows
complete testing of all transmission paths and port reflection characteristics. Agilent
multiport test systems eliminate time-consuming reconnections to the DUT, keeping
your production costs down and your volumes up. By reducing the number of RF
connections, you also:
•
lower the risk of misconnections
•
reduce operator fatigue
•
minimize wear on cables, fixtures, connectors, and the DUT

Chapter 1
Introduction and Installation
Introduction to the Multiport Test Set
Improve Your Competitiveness with a Fully Specified
Test System
A multiport test set coupled with an E5061A/E5062A network analyzer offers fully
specified performance at the actual test ports, whether you measure in a fixture or at
the end of test cables. Specified performance means you can:
•
get the same results no matter which test station you use to measure your DUT
•
correlate test data from many DUTs across multiple test systems
•
reduce measurement uncertainty to tighten your product specifications
•
increase customer confidence in your products
Eliminate Redundant Connection of Calibration
Standards with Test Set Cal
Calibrating a multiport test set using two-port error correction and a traditional
network analyzer requires a unique instrument state for each measurement path,
forcing many redundant connections of calibration standards. As the number of
ports increases, so does the number of connections required to calibrate all possible
measurement paths. Full calibration of the multiport test system is quick and simple
when performing a Test Set Cal:
•
connect short, open, and load standards only once to each measurement port
•
minimize the number of through standards required during calibration
Chapter 1

Introduction and Installation
Introduction to the Multiport Test Set
Reduce the Effects of Test-System Drift with SelfCal
SelfCal is an internally automated calibration technique that uses solid-state
switches to measure calibration standards located inside the test set. SelfCal
executes automatically in just a few seconds (at an interval you define), so the
impact to your test process is minimal. Use SelfCal to:
•
re-calibrate your multiport test system, returning it to the same measurement
accuracy achieved immediately after performing a Test Set Cal
•
reduce the effects of test-system drift, improving overall measurement accuracy
between Test Set Cals
Since SelfCal does not correct for drift associated with interconnect elements
between the test set and your DUT, it is essential to use high-quality test cables,
adapters, and fixtures to ensure the best measurement accuracy.
Decrease Calibration Times and Increase Production
Throughput
With SelfCal, a Test Set Cal needs to be performed about once per month, if within
the specified temperature range. This is unlike other test systems that typically
require calibration once or twice a day. Using Test Set Cal and SelfCal, you can:
•
easily reduce your overall calibration times by a factor of twenty or more
•
increase the amount of time a test station can be used for measuring
devices—typically, by three days per month.
Improve Measurement Accuracy with Two-Port
Calibration
When using a multiport test set with an E5061A/E5062A with the option 275
S-parameter test set, Test Set Cal and SelfCal support full two-port calibrations.
Two-port error correction greatly improves the effective load match of the test
system, providing excellent measurement accuracy.

Preventive Maintenance
Preventive Maintenance
Preventive maintenance consists of checking the front panel connectors. This should
be done at least every six months — more often if the test set is used daily on a
production line or in a harsh environment.
Visually inspect the front panel connectors. The most important connectors are
those to which the DUT is connected. All connectors should be clean and the center
pins centered. The fingers of female connectors should be unbroken and uniform in
appearance. If you are unsure whether the connectors are good, gauge the
connectors to confirm that their dimensions are correct.
CAUTION
Never connect 50 ohm cables to the front panel 75 ohm connectors of the analyzer
or test set. Otherwise, irreparable connector damage will occur.
Cleaning the Test Set
Use a dry cloth or one slightly dampened with water to clean the external case parts.
Do not attempt to clean internally.
WARNING
To prevent electrical shock, disconnect the test set from power mains before
cleaning.

This chapter presents information on the following topics:
•
Test Set Cal: An Overview
•
Test Set Cal and SelfCal: Theory of Operation
Measurement calibration is a process that improves measurement accuracy by using
error correction arrays to remove systematic measurement errors. By implementing
the Test Set Cal and SelfCal features on your multiport system, you can increase the
accuracy of your measurements and increase the throughput of your multiport
measurements by eliminating frequent and lengthy calibration procedures.

Test Set Cal
A Test Set Cal is a calibration that should be performed when you first set up your
test system and thereafter on a regular, but relatively infrequent basis. The time
interval between Test Set Cals is dependent mainly on temperature. If the operating
temperature of the analyzer and test set is within the specified range, the
recommended time interval is about once a month. A Test Set Cal requires you to
connect calibration standards to all of the ports to be used.
See “Test Set Cal: An Overview” to learn how to perform a Test Set Cal.

Chapter 3
Test Set Cal and SelfCal
Introduction
SelfCal
A SelfCal is an automated internal system calibration that should be performed on a
regular, frequent basis. If the operating temperature of the analyzer and test set is
within the specified range (refer to Chapter 8), the recommended time interval is
about once an hour. A SelfCal does not require removal of the DUT or external
connections of calibration standards. The SelfCal uses the results of the most recent
Test Set Cal along with measurements of internal, electronically switched open,
short, load, and through transfer standards to remove the drift of the network
analyzer and multiport test set due to environmental variations.
See “Test Set Cal and SelfCal: Theory of Operation” for detailed information on
how the Test Set Cal and SelfCal work together.
NOTE
Agilent recommends that you use the Test Set Cal and SelfCal features whenever
you are using your multiport system. If you prefer, you can select from traditional
analyzer calibrations, although in doing so the Test Set Cal and SelfCal features will
not be available. Refer to your analyzer’s User’s Guide for information on these
traditional calibrations.

Test Set Cal: An Overview
Test Set Cal: An Overview
To perform a Test Set Cal the following steps are required and are explained in
detail in this section:
1. Set up measurement parameters, such as frequency range, power level, number
of measurements points, etc.
2. Determine the best position for the calibration reference plane.
3. Determine the type of calibration kit you will need to match the connectors at
your calibration reference plane.
4. Determine the number of test set ports to be used.
5. Perform the Test Set Cal.
The following optional steps are also explained in detail in this section:
6. Save the Test Set Cal.
7. Recall the Test Set Cal.
8. Copy the Test Set Cal.
9. Execute the SelfCal.
Setting Up the Measurement Parameters
You will need to determine the measurement parameters for your Test Set Cal by
determining all the measurements you will be making on a particular device and
setting your parameters accordingly. The analyzer will be able to accurately
interpolate between error-correction data points when most parameters are changed.
However, some special considerations are discussed below.
Frequency Range
You should set your frequency range to the narrowest span possible that will cover
all of the measurements you will be making. The analyzer uses a fixed number of
frequency points during a calibration and interpolates as the frequency span is
narrowed. Setting the analyzer to the narrowest span possible for your
measurements will ensure the most accurate calibration. For example, if you will be
measuring a device that requires three different measurements, set your start
frequency to the lowest frequency used among the measurements and your stop
frequency to the highest frequency used among the measurements. See Figure 3-1.
32
Chapter 3
Test Set Cal and SelfCal
Test Set Cal: An Overview
The analyzer will interpolate between calibrated measurement points when the
frequency span is narrowed. However, you should be aware that best measurement
accuracy is compromised with this interpolation.
Figure 3-1
Frequency Range Example
NOTE
It is recommended that you set your stop frequency to 1300 MHz. The performance
of the test set is not specified above 1300 MHz.
Using this method of calibration will yield accurate measurements with optimum
throughput. If your accuracy requirements are more important than your throughput
requirements, you may want to perform a separate Test Set Cal for each
measurement setup, which eliminates the need for the analyzer to use interpolation.
Chapter 3
33
Test Set Cal and SelfCal
Test Set Cal: An Overview
Other Parameters to Consider
The following parameters, if changed after calibrating, will not invalidate the
calibration, but will cause the “C?” notation to appear at the status bar of the
display:
•
Sweep time
•
Number of points
•
Power level
•
IF bandwidth
The “C?” notation indicates that a measurement parameter has changed after a
calibration was performed. For best accuracy, avoid measurements which cause the
“C?” notation to appear.
There is a trade-off between selecting the parameters for best measurement accuracy
and the resulting time required for the SelfCal routine. Generally, as your
parameters are modified for the greatest accuracy, the time required for a SelfCal
increases. For example, selecting a large number of points and a narrow system
bandwidth will improve measurement accuracy but will increase the time needed for
SelfCal. Therefore, when choosing parameters, you will have to weigh the
importance of measurement accuracy versus throughput.
Determining the Best Position for the Calibration
Reference Plane
Most often you will not be connecting your DUT directly to the test set front panel.
More likely, you will be connecting your DUT to a test fixture or test cables that are
connected to the test set. See Figure 3-2 for an example. The calibration reference
plane is where you connect your calibration standards, and the measurement
reference plane is where you connect your DUT. Best measurement results occur
when these reference planes are aligned so that you calibrate out the effects of the
test fixture and its associated cables and hardware. Figure 3-2 illustrates how to
align the reference planes by connecting your calibration standards at the same point
that you connect your DUT.

35
Test Set Cal and SelfCal
Test Set Cal: An Overview
CAUTION
Although the Test Set Cal can calibrate out the effects of your external hardware, the
drift-removing features of the SelfCal cannot remove drift associated with any
external fixtures or cabling. See Figure 3-4.
Be sure that all external fixtures and cables are extremely stable. Agilent
recommends the use of semi-rigid cabling external to your multiport test set. Design
fixturing such that movement of all cables and connectors is minimized.
Determining the Type of Calibration Kit to Use
For the most accurate calibrations and measurements, you should select a calibration
kit to match each connector of your DUT. This will ensure that no adapters are
needed after a calibration has been performed. Procedures to select a calibration kit
is given below. For more information on calibration kits, refer to the
E5061A/E5062A User’s Guide.
Step 1. Press [Channel Next] or [Channel Prev] to select the channel for which you want
to select the calibration kit.
Step 2. Press [Cal].
Step 3. Press Cal Kit.
Step 4. Select the calibration kit you use.
NOTE
Alternatively, you can also use [Cal] - Test Set Cal - Calibration - Cal Kit to select a
mechanical calibration kit. Follow these steps.
Step 1. Press [Channel Next] or [Channel Prev] to select the channel for which you want
to select the calibration kit.
Step 2. Press [Cal].
Step 3. Press Test Set Cal - Calibration - Cal Kit and select a calibration kit you want to use
from the softkey menu.
NOTE
The calibration kit definitions for Port 1 are used for the test set ports with an odd
number, while the definitions for Port 2 are used for the ports with an even number.

Chapter 3
Test Set Cal and SelfCal
Test Set Cal: An Overview
Determine the Test Set Ports to Be Used
To save time, calibrate the lowest number of ports necessary for your test setup. For
example, if your test setup requires the use of only 6 of the available twelve ports,
calibrate for 6 ports; there is no need to spend the time to calibrate all twelve ports.
The selection of the number of ports is necessary, in part, in order to perform the
minimum-through portion of the Test Set Cal. This portion occurs during the
calibration when measuring through standards for a transmission measurement (S21
or S12) or measurements using 2-port calibration. Suppose that you have a 6-port
DUT and that you have selected the ports 1 to 6 to calibrate on your test set. A
traditional network analyzer calibration would require (in addition to connecting
opens, shorts, and loads to all connectors) that you connect a through standard
between every possible pairing of the 6 test set ports in order to measure all possible
transmission paths. This would mean 15 different connections of through standards,
each needing its own separate calibration file. The Test Set Cal simplifies this
process by only requiring a through-standard connection between 3 adjacent port*
pairs of the 6 test set ports:
•
Port 1 to Port 2
•
Port 3 to Port 4
•
Port 5 to Port 6
The analyzer calculates the remainder of the test set port combinations and saves the
data as only one calibration file. The test set calibration can be done in any
combination of the adjacent port pairs, [1, 2] and [5, 6] for example. This results in
significant calibration-time savings, which improves your measurement throughput.
Performing the Test Set Cal with a Mechanical
Calibration Kit
This section describes how to perform the Test Set Cal with a mechanical
calibration kit.
Step 1. Press [Channel Next] or [Channel Prev] to select the channel for which you want

Step 2. Press [Cal].
* Adjacent ports are those which share an internal through calibration standard. Adjacent ports are: [1, 2], [3, 4], [5, 6], [7, 8], [9, 10], [11, 12].

chapter.
Step 5. Press Port x-y (a port pair for which you want to execute calibration).
NOTE
The multi-port test set calibration is performed for each port pair. If you want to use,
for example, ports 1 and 3 for measurement, calibration must be performed for 1-2
and 3-4.
Step 6. Connect the open standard to the Port x side and press Port x Open to measure
calibration data.
Step 7. Connect the short standard to the Port x side and press Port x Short to measure
calibration data.
Step 8. Connect the load standard to the Port x side and press Port x Load to measure
calibration data.
Step 9. Connect the open standard to the Port y side and press Port y Open to measure
calibration data.

Step 11. Connect the load standard to the Port y side and press Port y Load to measure
calibration data.
Step 12. Connect the thru standard between ports x and y side and press Portx- y Thru to
measure calibration data.
Step 13. Press Return to return to the port selection menu.
Step 14. Repeat Step 5 through Step 13 for necessary port pairs.
NOTE
When you calibrate the same port pair in multiple channels, you can reduce the
number of standard connections by measuring a standard while changing
measurement channels. You don’t need to complete the step 5 through 13 before
you perform calibration in other channel, thus you can measure standards for Test
Set Cal in parallel in multiple channels.
Step 15. Press Done to finish the calibration of the multi-port test set. The calibration
coefficients are calculated and saved by this operation.

Test Set Cal: An Overview
Calibrating: Insertable Port Pairs versus Noninsertable Port
Pairs
During the through portion of the calibration, if an adjacent port pair (for example,
1-to-2, 3-to-4, 5-to-6, etc.) can be connected directly without using a cable or an
adapter, the port pair is insertable. If an adjacent port pair can only be connected by
using a through cable or an adapter, the port pair is noninsertable. If the port pair is
noninsertable, the through cable or adapter is not used when the DUT is measured,
so its electrical delay must be subtracted out. This is done by modifying the
definition of the through-standard in the calibration kit for each port.
Most test fixtures have fixed-location connectors, so their port pairs can only be
connected by using a through cable. During the calibration you will be prompted to
connect a through cable between specific port pairs. If you can connect your cables
to the test set so that the cables’ adjacent port pairs are male-to-female, all of your
port pairs will be insertable. Configuring your test setup this way saves calibration
time and improves your measurement throughput.

Copying the Test Set Cal.
The E5061A/62A lets you temporarily save Test Set calibration data only for each
channel and copy it to another channel. When the same calibration data is used in
multiple channels, you can reduce calibration time by using this method instead of
doing the same calibration multiple times. The procedure is as follows:
Step 1. Press [Channel Next] or [Channel Prev] to select the channel for which you want
to save calibration data temporarily.
Step 2. Press [Save/Recall].
Step 3. Press Save Channel.
Step 4. Press one of Cal Only A through Cal Only D.
NOTE
An area with an asterisk (*) to the right of Cal Only x contains saved data already. If
you press the key, the previous calibration data is deleted and new calibration data is
written over it. In this case, the previous calibration data cannot be restored.
Step 5. Press [Channel Next] or [Channel Prev] to select a channel to which you want to
copy calibration data.
Step 6. Press [Save/Recall].
Step 7. Press Recall Channel.
Step 8. Press Cal Only x in which you have saved calibration data to read it out.
NOTE
Only keys for which saved data exists are active.

Test Set Cal and SelfCal
Test Set Cal and SelfCal: Theory of Operation
Test Set Cal and SelfCal: Theory of Operation
Adding a multiport test set to the analyzer degrades raw performance of the test
system as well as introduces drift. Test Set Cal provides the vector error correction
that allows the system to achieve good performance. A Test Set Cal is a calibration
that is performed on a regular, but infrequent basis. The results of the Test Set Cal
are used by the SelfCal feature to remove the drift associated with the hardware of
the test set and analyzer to return the multiport system to an accurately calibrated
state.
There are two steps to the Test Set Cal:
•
The first step requires you to connect calibration standards (from a calibration
kit) and your own through-cables to the calibration reference plane. The
analyzer measures the known reference standards and uses those measurements
to compute error correction coefficients.
•
The second step occurs once you are done measuring the calibration standards
and store the Test Set Cal data. The multiport test set contains electronically
switched open, short, load, and through standards behind each port. (See Figure
3-3. This illustration depicts a two-port test set. The same internal standards are
also included behind every port of your test set.) These standards are very stable,
yet their calibration definitions are not known like the mechanical standards.
During this second step, the analyzer makes a measurement of each internal
standard and then, using the error coefficients that were computed from the
measurements of the external standards, derives a very accurate calibration
definition for each internal standard. Once this has been done, the internal
standards act as “transfer standards” for future automatic calibrations called
SelfCals.

Test Set Cal and SelfCal: Theory of Operation
Figure 3-3
Internal Transfer Standards
A SelfCal is an automatic measurement of the test set internal standards that allows
the system to remove system drift that occurs due to environmental changes such as
temperature. SelfCal allows the multiport system to recalibrate itself without having
to disconnect the DUT or connect any additional external standards or cables to the
system.
A SelfCal can be initiated manually. It is also possible to automatically perform a
SelfCal at regular, frequent time intervals. If the operating temperature of the
analyzer and test set is within the specified range (refer to Chapter 8), the
recommended time interval is about once an hour.
CAUTION
Performing a Test Set Cal will effectively calibrate out the initial effects of any
external cabling and/or test fixtures. However, it must be noted that although the
SelfCal can remove drift internal to the measurement system, it cannot remove any
drift associated with cables, test fixtures and connections beyond the internal
transfer standards.
As shown in Figure 3-4, the Test Set Cal initially removes the effects of drift
associated with hardware in the area designated by arrow “A.” SelfCal can only
remove the effects of drift from the area designated by arrow “B.”
46
Chapter 3
Test Set Cal and SelfCal
Test Set Cal and SelfCal: Theory of Operation
Drift can be minimized by controlling the environmental temperature and humidity,
and by using high quality connectors, semi-rigid cables, and fixturing that reduces
cable movement to a minimum.

SCPI Command Reference
Syntax
Notational conventions in this command reference
This section describes the rules to read the description of the commands in this
chapter.
Syntax
Part with heading "Syntax" describes the syntax to send a command from the
external controller to the E5061A/E5062A. A syntax consists of a command part
and a parameter part. The separator between the command part and the parameter
part is a space.
If there are several parameters, the separator between adjacent parameters is a
comma (,). 3 points (…) between commas indicate that parameters in that part are
omitted. For example, <value 1>,…,<value 4> indicates that 4 parameters, <value
1>,<value 2>,<value 3>,<value 4>, are required. String-type parameters, <string>,
<string 1>, and so on, must be enclosed in double quotation marks (").
You can omit the lowercase letters in syntax. For example, ":CALibration:CABLe"
can be shortened as ":CAL:CABL.
The definition of symbols used in the syntax is as follows:
<>
Characters enclosed in this pair of symbols are necessary
parameters when sending the command.
[]
Part enclosed in this parenthesis pair can be omitted.
{}
Part enclosed in this parenthesis pair indicates that you must
select one of the items in this part. Individual items are
separated by a vertical bar (|).
For example, ":CALC:CORR:EDEL:TIME 0.1,"
":CALCULATE1:SELECTED:CORR:EDEL:TIME 25E-3," and so on are valid for
the syntax given below.
Syntax
:CALCulate{[1]|2|3|4|5|6}[:SELected]:CORRection:EDELay:TIME <value>
Description
Part with heading "Description" describes how to use the command or the operation
when executed.

Parameters
Part with heading "Parameters" describes necessary parameters when sending the
command. When a parameter is a value type or a string type enclosed with <>, its
description, allowable setup range, preset (factory-set) value, and so on are given;
when a parameter is a selection type enclosed with { }, the description of each
selection item is given.
For a value-type parameter noted with "MAX or MIN is available," you can use
MAX (or MAXIMUM) and MIN (or MINIMUM) as its parameter instead of a
value, which specifies the maximum value and minimum value within the allowable
setup range, respectively.
Query response
Part with heading "Query response" describes the data format read out when query
(reading out data) is available with the command.
Each readout parameter is enclosed with {}. If there are several items within {}
separated by the pipe (|), only one of them is read out.
When several parameters are read out, they are separated with a comma (,). Note
that, 3 points (…) between commas indicate that the data of that part is omitted. For
example, {numeric 1},…,
{numeric 4} indicates that 4 data items, {numeric 1}, {numeric 2}, {numeric 3},
and {numeric 4}, are read out.
<newline><^END> after the parameters is the program message terminator.

SCPI Objects
The SCPI objects are created to realize the SCPI commands of the E5061A/E5062A
with the COM interface. For information on the basic use of the SCPI objects, see
“SCPI Objects” on page 87.
The conversion rules from the SCPI commands when writing SCPI object messages
are as follows:
•
SCPI. must be at the beginning. Notice that the IEEE common commands start
with SCPI.IEEE4882. and "*" is omitted.
•
Replace colons (:) used as the hierarchical separator symbol with dots (.).
•
The number written in the object message is specified with ( ).
•
You cannot omit the command message in the syntax.

Notational Rules of COM Objects
This section describes the rules for the description of the COM objects in this
chapter.
Object Type
Part with heading “Object type” describes the type of the E5061A/E5062A COM
object. The E5061A/E5062A provides properties and methods as the types of COM
objects. In the E5061A/E5062A COM objects, COM objects to set (send)/read
(return) the state of the E5061A/E5062A using variables are defined as property and
ones to prompt some kind of processing as method.
Syntax
Part with heading “Syntax” describes the syntax to send a COM object from the
E5061A/E5062A VBA to the E5061A/E5062A. The syntax consists of the object
part and the set/read part, with an equal “=” inserted between them. Variables are
indicated by italicized letters. Variables with () are indices. For indices with ()
having their preset values, you can omit “(variable),” and, if omitted, the preset
values are automatically set.
There are the following 3 types of syntax for coding using objects.
"Object (property) = variable": to set the stat of the E5061A/E5062A.
variable=object (property): to read the stat of the E5061A/E5062A.
"Object (method)": to make the E5061A/E5062A perform some processing.
Description
Part with heading “Description” describes how to use the COM object or the
operation when executed. COM objects used only to read the state of the
E5061A/E5062A are indicated with “Read only” and ones used only to set the state
of the E5061A/E5062A “No read.”
88

COM Object Reference
Variable
Variable
Part with heading “Variable” describes necessary variables when using the object. It
gives the description, data type, allowable range, preset value, unit, resolution, and
notes for variable (italic) shown in the syntax.
Variables declared as the string data type (String) are case insensitive. For variables
of the string type that indicate arguments (written as Param in the syntax), you can
omit lower-case letters.
The data types of the E5061A/E5062A COM objects include 5 types as shown in
Table 7-1. Before using variables, declare the data type of each variable. If you do
not declare the data type of a variable, it is automatically dealt as the variant type.

About This Chapter
This chapter describes the performance and features of the 87075C multiport test
sets. The performance of a test set is formally described in this chapter under the
categories Specifications and Supplemental Information. Performance of the test set
to specifications is covered by the Agilent Technologies warranty1. Supplemental
information may be useful in the application of the test set, but this performance is
not covered by the Agilent Technologies warranty. Supplemental information
includes characteristics, typical, and nominal values.
1. During the warranty period, Agilent Technologies repairs or adjusts products, at no cost, that do not meet the specifications. (This statement does not
constitute the actual warranty. See “Warranty”.)

Chapter 8
Specifications
Definitions
All specifications and characteristics apply over a 25 °C ±5 °C range (unless
otherwise stated) and thirty minutes after the instrument has been turned on.
Specification (spec.): Warranted performance. Specifications include guardbands to
account for the expected statistical distribution, measurement uncertainties, and
changes in performance due to environmental conditions.
Characteristic (char.): A performance parameter that the product is expected to
meet before it leaves the factory, but is not verified in the field and is not covered by
the product warranty. A characteristic includes the same guardbands as a
specification.
Typical (typ.): Expected performance of an average unit which does not include
guardbands. It is not covered by the product warranty.
Nominal (nom.): A general descriptive term that does not imply a level of
performance. It is not covered by the product warranty.
Calibration: The process of measuring known standards from a calibration kit to
characterize the systematic (repeatable) errors of a network analyzer.
Corrected (residual) Performance: Indicates performance after error correction
(calibration). It is determined by the quality of calibration standards and how well
“known” they are, plus system repeatability, stability, and noise.
Uncorrected (raw) Performance: Indicates instrument performance without error
correction. The uncorrected performance affects the stability of a calibration.
Test Set Cal: The calibration of a multiport test system requiring the connection of
known calibration standards to all of the test ports that will be used for
measurements.
SelfCal: An automated system calibration that uses calibration standards internal to
the test set and the most recent Test Set Cal data to calibrate the test system.
Environmental Specifications: Environmental specifications bound the external
conditions for which the specifications are valid. The environmental specifications
also bound the external conditions the test set may be subject to, without
permanently affecting performance or causing physical damage.

1. This is the match of the test set port which has been selected as the source port. The test set interconnect reflection port must be terminated with a load standard from either the 85036B/E calibration kit
(for the 87075C).
2. This is the match of any test port that is unselected (not in the measurement path). Only the source
port of the test set is selected when you make a reflection measurement with 1-port calibration. Only
the source and load ports of the test set are selected when you make a transmission or reflection measurement with 2-port calibration.
3. This is the match of the test set port which has been selected as the load port. A transmission or 2-port
measurement is required for a test port to be selected as the load port. The test set interconnect transmission port must be terminated with a load standard from either the 85036B/E calibration kit (for the
87075C).
4. This is the match of the test set interconnect ports (transmission and reflection ports) with the test set
in transmission, or 2-port mode. The selected test set test ports must be terminated with load standards
from either the 85036B/E calibration kit (for the 87075C).
5. This is crosstalk of the test set measured between the test set’s interconnect ports, with shorts on the
selected test ports. Crosstalk is computed by normalizing the result of an isolation measurement to a
through measurement between the two ports such that the path losses are taken into account. Isolation
is defined as the transmission signal measured between any two ports of the test system when these
two ports are terminated with shorts. The specification assumes that the test set crosstalk has not been
calibrated. Adjacent ports are defined as: 1&2, 3&4, 5&6, 7&8, 9&10, and 11&12.

Automated Performance Tests
Automated Performance Tests
The performance verification tests make up the VBA performance test software
program. Your network analyzer is required to execute an VBA program to verify
test set performance.
The performance verification tests are designed to verify specifications for the test
set as listed in Table 8-2.
The performance test software uses traditional analyzer calibrations rather than a
Test Set Cal. This is because the multiport test set is treated as a DUT by the
analyzer.
The program file name is “87075C_PT_with E506162A.vba”. To perform the
performance test for the 87075C, execute the program in accordance with the
following procedure.
Step 1. Connect a mouse and an external keyboard to the E5061A/E5062A’s rear panel
connectors, then turn the E5061A/E5062A on.
Step 2. Insert the program disk.

Troubleshooting
Troubleshooting
Refer to Chapter 1, “Introduction and Installation,” to make sure the test set is
connected properly to the analyzer and that the analyzer has been configured for use
with the multiport test set.
Troubleshooting consists of isolating the cause of any problem to an individual
assembly. The multiport test set has three main assemblies:
WARNING
•
power supply
•
LED display board
•
main switch board assembly
Line voltage may be present on exposed metal heat-sinks and other
components contained on the power supply. Observe all safety precautions.
The Power Supply
WARNING
For continued protection against fire hazard, replace fuse only with same type
and ratings (H 3.15 A, 250 VAC). The use of other fuses or materials is
prohibited.
The line fuse is located on the power supply assembly. See the parts list (later in this
chapter) for the fuse part number. The power supply is autoranging and will accept
from 90 to 254 volts AC. The power supply provides ±15 volts and +5 volts to the
main board assembly via a four wire cable assembly. The pin-out is as follows:

6

DS702
Chapter 9
Service
Troubleshooting
If the power supply voltage is measured while the cable is disconnected from the
main board assembly, the +5 volt supply may not function. It requires a load of at
least 0.5 amps to operate properly. This can be simulated with any 10 ohm, 5 watt
resistor.
The LEDs on the main board assembly indicate that power is being received. The
fan operates from +12 volts and has its own regulator derived from the +15 volt
supply. If the fan does not operate, check the +12 volt supply at test point TP706.
The LED Display Board
If all performance tests pass, but the LED indicators on the front panel do not
operate, then the most likely cause of failure is the LED display board assembly or
its associated ribbon cable.
The Main Switch Board Assembly
If any of the performance tests fail and the cause is not obvious, such as a bad power
supply, damaged or loose connector, etc., then the recommended course of action is
to replace the main board assembly.
IMPORTANT
Do not remove or adjust the shields on the main switch board assembly. The
placement of shields and gaskets on the assembly is critical to the performance of
the test set. Changes should only be made at the factory.
IMPORTANT
If the main board assembly is replaced, it is critical that the socketed ID ROM
(U801) be transferred from the old board assembly to the new one. The replacement
board assembly will not contain an ID ROM when purchased, and will not function
properly without this ROM. In the unlikely case that this ROM should fail, contact
Agilent Technologies. See page 120 for contact information.
Post-Repair Procedure
If the main board assembly or power supply is replaced, a complete performance
test should be performed. A Test Set Cal should be performed also (see “Test Set
Cal: An Overview”) and stored on a disk for access by the end user.
